eMath September 2017 Newsletter

A new school year has started in the great Northeast. The light is getting dimmer while the trees are getting prettier. We’ve been all sorts of busy this past month at eMathInstruction working on making our site easier to use and coming up with add-ons to the courses. Let’s get right into those.

Let’s begin with the Common Core Algebra I Add-Ons. This month we’ve added two new lessons. One fits into Unit #3 between Lesson 6 and 7 (so I’ve given it Lesson 6.5). The lesson title is Motion and Average Rate of Change. We’ve seen quite a few motion problems on the Common Core Algebra I Regents Exam, so I thought it was time we devoted a lesson just to them. We also added Unit 4 – Lesson 9.5 on Solving Absolute Value Equations. We emphasized simple algebraic equations and more complicated graphical ones. Interestingly enough, there is no mention of solving any absolute value equations algebraically in the Common Core Standards, only graphically. Which is why you’ve only seen them that way on the Regents exams. Here’s a good example from June of 2016.

Moving right along to Common Core Geometry, recall that our add-ons to the Common Core Geometry curriculum this year will be the Unit Reviews and Unit Assessments. This month we’ve added on every student’s favorite, Unit #3 – Triangle Congruence Proof. We’ve given you a long set of additional problems and a nice assessment. We’ve also published the standards alignment documents in our Table of Contents section. If you’ve been itching to do some standards mapping to our Geometry curriculum, check out that link.

For our Common Core Algebra II Add-Ons this month we bring you an additional assessment and lesson. We created a Unit 3 Formative Assessment make up exam. This rounds out the Form B exams for Common Core Algebra II. Now each unit has both an assessment and a mirror make up assessment. We may consider adding additional make up assessments if teachers think it’s a good idea. We also added a lesson to Unit 4. Lesson 7.5 is titled Exponential Modeling Revisited and looks at moving between time units in exponential modeling. For example, if a growth model is given in hours, what would its equivalent look like if modeled in days instead. We’ve seen numerous questions on the New York State CC Alg II Regents exam on these types of questions.

Finally there is the old-faithful Algebra 2 with Trigonometry Add-On for this month. After a great deal of resistance on the part of yours truly, I’ve finally created a lesson on factoring trinomials with a method other than guess and check. I created Unit 3 – Lesson 6.6 – Factoring Trinomials Using the AC Method. Teachers who are familiar with this method of factoring already probably have a sense for how this lesson will work. I still believe guessing and checking is important for students, but this method does work and does produce reliable results, at least it does if a student can find the two integers that satisfy the product and sum conditions.

A final note on add-ons in general. I’ve been struggling with how to arrange them and have decided to keep placing resources into the add-ons so that they are in Unit order. That means add-ons from last year mix with ones from this year. For teachers who want to only see new add-ons, this isn’t the greatest way of organizing them. Still, for the teacher who just wants to see what resources are there for a particular unit, this is a very effective way to  have them arranged. As always, if you have any thoughts either way, feel free to reach out to me.

In other New York Math News, it looks like the Board of Regents finally voted on and adopted the New York State Next Generation Mathematics Learning Standards (or NYSNGMLS). Click on that link to open the full 170 page pdf document on the standards. They were just adopted so there are many news articles on them. Here’s a good one out of Albany itself:

Goodbye Common Core: New York’s New English, Math Standards Are Here – Albany Times Union

One of the most important parts of this piece is the following excerpt:

I’ve been waiting on some official word of the timeline before we started to modify our own text. Looks like I have a few years to make that happen. We may, when the time comes (2020), publish a New York edition to our Common Core texts. I’m hopeful by that time we’ve moved to an electronic only textbook. Thanks to Brian Battistoni, my good friend and colleague from Arlington High School, for the heads-up that the Next Gen standards had been officially adopted.

Well, I think that’s it for now. I’m hopeful that everyone has had a good start to their school year. As always, if you are having any troubles with your subscriptions or any suggestions on the curriculum, don’t hesitate to email me at: I’m busy, but never too busy to help.

eMath May Newsletter

Well, it’s finally mid-May, which means that nice weather has returned to upstate New York. It also means that we are hitting the homestretch of the school year, with some schools finishing up quite soon. New York schools don’t finish until the third or fourth week of June, but final exams (Regents Exams) in math come in mid-June.

We have lots of exciting news and one last round of add-ons for this school year. First, we’ll start with the news which is mostly about Common Core Geometry. We are now done with the workbook and are printing up a bunch for summer orders. The answer key is being uploaded as I write this newsletter. It will definitely be available by Memorial Day weekend if not by the end of this week. We continue to record the videos and upload them as they are edited. We hope to have all of Unit 2 uploaded this week. That’s the particularly challenging unit on Transformations and Rigid Motions.

Another exciting set of events we have coming up are our Instagram Live Review sessions for the New York State High School Regents Exams. We will hold one review session for each of Common Core Algebra I, Common Core Geometry, and Common Core Algebra II. We are still settling on final times, but right now here is our proposed schedule:

Common Core Algebra I – Sunday, June 11th  from 3 to 5 p.m.

Common Core Algebra II – Wednesday, June 14th from 6 to 8 p.m.

Common Core Geometry – Thursday, June 15th from 6 to 8 p.m.

We will simply be taking questions from students who are watching the Live Session. We will have all of the previous Regents exams open and can work out questions on any of those or anything else the students throw our way. For those of you not familiar with Instagram, students will have to follow me (@kirkweiler). As well, they will only be able to watch via their phones as Instagram is not a computer or tablet based app (how weird is that?). There may be work arounds for this limitation. We went with Instagram instead of Facebook because we found that most teenagers have Instagram accounts, but not Facebook accounts.

Please do let us know if you have thoughts about the timing of the sessions. We tried to pick what we thought made the most sense after speaking with both students and teachers about it.

Our final round of add-ons for this school year are all about review materials. For each course, we added review quizzes for each unit. These are short, “keep them honest” quizzes that hit on major topics of each unit. They are only 10 points each and are designed to help a teacher get some feedback on where students are at on each unit, without taking up too much time for assessment during this last month of intense review. In Common Core Algebra I, we have a packet of quizzes for Units 4 through 10. For Common Core Algebra II we have these quizzes for all 13 units. For Algebra 2 and Trig, we supply the quizzes for Units 7 through 13.

We will keep posting eMath Newsletters in June and July, but won’t be posting additional add-ons during this time. We will begin to add new ones in the August newsletter, starting with our first round ever of Common Core Geometry add-ons. We plan making the Unit Reviews and Assessments the add-ons for Common Core Geometry next year, which is why the price of those subscriptions are slightly less than others. We don’t know yet what the add-ons will be for the other courses, but plan on exploring Performance Tasks for these courses as well as creating some lessons that address the modifications we are seeing in the Common Core curriculum in New York state.

For now, have a great May! Enjoy Memorial Day weekend and the final sprint. I’ll see you back here in mid-June!!!

eMath April Newsletter

Spring has sprung here in upstate New York. We’ve had a beautiful April so far. Many school districts in New York are just coming off of spring break, although lucky ones might still be on it. We waited a bit longer than usual to post our newsletter because of both Passover and Easter, but the add-ons are up on the site for the three courses and we have much news to tell.

I’m going to start with Common Core Geometry. We’ve been busy on all fronts with that course. My producer, Joey Shavelle of JoLo Studios, and I have been working on the videos for the course. We have about 70% of them recorded and about 25% of them edited and posted at this point. We plan on having them all done and linked to on our site by the beginning of August. Most will be up by the end of this school year. We decided to edit and post all of them for our Unit #4 on Constructions because I know how easily students forget these techniques.

Construction Unit

We are also working hard to do final edits on both the workbook (must remove typos!!!) and the answer key. Our plans are to have both workbooks and the answer key subscriptions available by Memorial Day weekend of this May. We have priced the Teacher Plus subscriptions at $125 per subscription, which is less expensive that those for our other courses. We did this because the first version of the answer key will not have Unit Reviews and Assessments. BUT, we will be adding those on as we move through the year next year. We plan to publish the Unit 1 Review and Assessment as our August add-on for the course.

In other exciting, and nerve-racking news, eMathInstruction will do its first live video event this June and hold a review for each of the major New York State Regents high school math exams (i.e. CC Algebra I, CC Geo, and CC Alg II). We considered a number of platforms and talked to the demographic we want to reach (i.e. the students) and decided to try it on Instragram Live. We believe this will allow us to field questions and answer whatever comes in. In order to ask questions and watch students will need to follow me. My Instagram username is @kirkweiler.  I’m planning on holding them on Monday, June 12th (Common Core Algebra I), Wednesday, June 14th (Common Core Algebra II) and Thursday, June 15th (Common Core Geometry).  I’m going to try to make these marathon sessions and probably try to go from 5 to 7 or 5 to 8. Please give me feedback on both dates and times. It’s a bit tricky given that Geo and Alg II are on the same day. We will do a practice run in early June. More details in our May newsletter.

O.k. Let’s discuss the Common Core Algebra I Add-Ons. As always, we want to give teachers tools that can use and modify. So, we rounded out our Form B assessments with a Unit #11 Formative Assessment Form B. This is the final unit in the course and we now have Form B assessments for each unit except Units #1 and #2 (perhaps add-ons for next year?). We also posted short, 10 point, review quizzes for Units #1 through 3 in a bundle (so a single file has them all). These are good quizzes to simply do a quick check of understanding for students. They are certainly not comprehensive assessment of all topics in the units (see Formative assessments for that).

For the Common Core Algebra II add-ons we bring you two resources for Unit #13 on statistics. First, we round out our formative assessments with a Form B assessment for Unit #13. As well, we created a packet with four extended statistical simulation problems similar to the ones that we’ve seen tested so far on standardized tests. We tried to make these problem accessible and hope that they give you some extra problems to help students grapple with this type of thinking. I have to say that I spoke with a relative of mine who is a math professor at Penn State and even he is a bit confused by the statistical simulation questions.

Finally, we have our Algebra 2 with Trigonometry add-ons. For this course we created review quizzes for the first six units that are also just 10 points each. These small quizzes allow a teacher to review a unit and hold students accountable for the material, but not take an entire period for the assessments. Most of them consist of two to three multiple choice questions along with a few free response questions. We actually have 8 quizzes in this packet because we broke up the long units #3 and #6 in half to provide more feedback.

O.k. So, that’s about it. I need to get back to editing Common Core Geometry. I hope that everyone is enjoying the nicer weather and all that comes with it. The school year is now more than three-quarters over and we are just about in the homestretch. See you all in May.

eMath March Newsletter

It’s March 14th. Pi Day!!! Here’s a nice pi-ku for you:


Also, in the greater Northeast, it is Snowpocalypse 2017. So far about 9 inches have fallen with another 15 or so on the way.

We’ve been exceptionally busy lately here at eMathInstruction. I’m going to switch things up a bit in this newsletter and give you the news first and discuss add-ons second.

On the Common Core Geometry front we’ve been moving ahead nicely. We just received the first formal proof for the book.

Geometry Proof

That means once we’ve done one more round of editing it will be ready to go to press. We’ve also finished the rough draft of the answer key and will continue to work on it as well. We hope to have both workbooks and answer key subscriptions available for purchase by Memorial Day weekend. In our store, it appears that both the workbooks and answer keys have been sold out when in fact they aren’t even for sale yet. But, we can create Quotes for the two products if any schools need these for next year’s budgets.

Most of our time and energy now is being devoted to producing the Common Core Geometry videos. We will have full length lesson videos for each of the 95 lessons in the curriculum. We are now using a SMART Board and screen capture technology because of the more tactile approach to Common Core Geometry.

Videos will be posted as they are finished. Our target is to be done with all videos by July 1st. We will certainly have many of them posted before that time, so if students need refreshers on how to do various constructions or other topics, point them to our Common Core Geometry Course, which is now officially on our Home Page:

Home Page with Geometry #2

During the next two months, we will be very busy recording the videos, so it may take more time to get an email response and we will likely be able to take less calls than normal. We do promise to get back to everyone who communicates with us as fast as we can. Just please be patient with us as we head into the final stages of Common Core Geometry.

We also have news on the New York City front. With the help of the good, and extremely patient, people in the New York City Division of Contracts and Purchasing (DCP) and Instructional Materials Review Unit (IMRU) we are very close now to having our materials listed on ShopDOE/FAMIS. They are now reviewing our books and we hope they may be listed by the end of March or early April. We are fairly certain that NYSTL approval will come shortly afterwards. But, to be honest, we are still a bit confused about that process (no great surprise).

We’ve got new add-ons this month for our three main courses. For Common Core Algebra I Add-Ons we have two new additions this month. We’ve got a Unit #10 Formative Assessment Form B exam. That’s our unit on Statistics, so this is a nice beefy make-up modeled on the original. On top of that, we also spent a great deal of time this last month uploading all of our videos onto TeacherTube. We’ve heard throughout the years that some schools block YouTube. My district of Arlington never did block YouTube, or if they did they unblocked it many years ago. Anyhow, all of our links on our site will continue to be YouTube links. But for this month I created a TeacherTube Hyperlinked Table of Contents so that teachers and students can easily find the video they want.

For Common Core Algebra II Add-Ons it is a similar story. First up we have the Unit 12 Formative Assessment Form B. This assessment is for our unit in Probability, so we are getting close to the end of the course with this one. Next month, when we hit Statistics, we plan to offer a Form B assessment  as well as a packet of statistical simulation results that you can work with your kids on interpreting. Finally, we also have posted the TeacherTube Hyperlinked Table of Contents for that course as well.

For Algebra 2 and Trigonometry Add-Ons, we continue our trend of adding on Formative Assessment for the course. We never did this when we originally created the course some nine years ago. For this month we’ve added on the Unit 12 Formative Assessment (Statistics) and the Unit 13 Formative Assessment (Sequences and Series). We’ll have to think hard about what to add-on for the April and May rounds. Perhaps reviews quizzes?

Alright. Well, I hear the first round of blowing snow off my driveway coming. Stay safe and warm and have a happy Pi-Day! Lest we end this newsletter on anything but an odd note, here are three pies singing the digits of pi in Finish thanks to Phineas and Ferb:

eMath January Newsletter

It’s January in upstate New York, which means it is really, really cold with no end of winter in site. For our friends in Arizona and other warm climates, now is the time to really enjoy how great it is not to have radical season change. We are quickly heading towards the mid-year point here and we have eMathInstruction news to report and add-ons to add on.

Let’s get to those add-ons. First up are the Common Core Algebra I Add-Ons. We start with monster packet of factoring questions. I’ve always found it useful to have a day where I have kids practice on all of the major types of factoring and that’s exactly what this packet does. It is arrange by difficulty level, although with factoring that can vary. We then move on to Unit #8, on quadratics, with a Trinomial Perfect Square Warm-Up worksheet. We created this warm-up to give students who struggle with factoring a bit of practice with factoring perfect square trinomial before they start the process of completing the square. Finally, we have a Unit #8 Formative Assessment Form B exam. Again, these make-ups have been the most popular add-on so far so we will continue to crank them out for the course.

Moving on to the Common Core Algebra II Add-Ons, we have lots to offer this month. This month the add-ons are all centered on the length Unit #10 – Polynomial and Rational Functions. First up is a mid-unit quiz that assesses knowledge through Lesson #7. Next we have a lesson and homework set on the Sum and Difference of Perfect Cubes. This is likely different from what you might expect. I find memorizing the formulas for these two polynomial identities less than useful, so I emphasize factoring these by first finding a zero, then a factor, and then using Polynomial Long Division to finish the factoring. We of course offer up for this month a Unit #10 Formative Assessment Form B for all of those kids who miss the first one or just if you want to use a different one from the original. Lastly, we have a great graphing activity called the Polynomial Challenge. I put this out last year, but cleaned it up and made it better for this add-on. The activity uses Desmos and has kids find the equations for over 20 polynomial graphs. We did this at Arlington last year and it worked great. It’s hard to imagine any student working through this and then not understanding the connections between the zeroes of a polynomial and its graph.

Lastly we bring you the Algebra 2 with Trigonometry Add-Ons. As we promised at the beginning of the year, our emphasis for this year on Algebra 2 with Trigonometry was to  create and publish formative assessments for the course. For this month we are adding a Unit #8 Formative Assessment (Trigonometric Equations and Identities) and a Unit #9 Formative Assessment (Trigonometric Applications). These are challenging tests and will truly assess how well students have mastered the trigonometry in this course.

We continue to move along on many other fronts at eMath. We are on the verge of being listed on the New York City ShopDOE/FAMIS system. This should help all of the great schools in New York City to more easily order our products. We are also moving ahead on the Common Core Geometry Answer Key with approximately 70% of it completed in its first form. It should be ready for quoting purposes in February and ordering by Memorial Day weekend for next year. It will likely be a less costly subscription that our others because we plan on adding the unit reviews and assessments next year as add-ons. We will start the Geometry videos in mid-February and will likely be putting them up on YouTube as soon as we get each of them done and edited. We have some surprises coming with these videos, so watch for them.

That’s it for now. Enjoy the rest of your January and early February. Good luck to all the schools that will be administering January Regents exams here in New York. May your students think clearly (and get good night’s sleep the nigh before). As always, if you have any questions, please send them my way at:

eMath November Newsletter

Now that we’ve made it past Halloween and the election, it’s time for Thanksgiving and the winter holidays. As always, we’ve been busy here at eMathInstruction with Common Core Geometry, Course Add-Ons, and Conferences left and right. I’ll discuss each in turn, but let’s get right to the add-ons.

This month in our Common Core Algebra I Add-Ons we have our latest installment of Form B exams. We now have one posted for Unit #4 (Linear Functions) and Unit #5 (Linear Systems). We’ve gotten a lot of feedback from teachers about how much they enjoy having additional exams that mirror the originals. Perhaps in 2017-2018 we will start with the Form C exams. Who knows? As well as these resources, we also have an additional problem set on real world applications of Linear Systems. You can never have too many Linear Systems Word problems to choose from, so it’s great to have an additional set for those students who are struggling or just extra practice for all of your students.

We continue to follow the assessment theme in our Common Core Algebra II Add-Ons this month by publishing a Form B exam for both Unit #6 (Quadratic Functions) and Unit #7 (Transformations). Both exams mirror the original by assessing the same standards in a given problem while modifying it enough to be able to be used as a makeup exam or even a redo. As well as these assessments, we have also created another Desmos graphing activity. This activity on Transforming Functions should be done at the end of Unit #7 and will solidify student understanding of how modifying a function’s equation can change its graph. This would be a great activity to do on the day before a long break (hint, hint).

Finally, for Algebra 2 and Trigonometry Add-Ons, we supplied two additional assessments. As we’ve noted in previous newsletters, one of the big gaps in our Algebra 2 with Trigonometry curriculum is a lack of Unit assessments. This month we add a full unit quiz for Unit #5 (Complex Numbers) and a Formative Assessment for Unit #6 (Polynomial and Rational Functions). That second assessment is a beast. We highly recommend taking a look at it and thinking about the amount of time it will take your students to complete.

In other exciting news, we are coming closer and closer to be finished with Common Core Geometry, at least in its Beta Version. We now have 9 out of 10 units posted, with our latest unit, Circle Geometry, posted just this morning along with the add-ons. Check out all of the units by going over to our Courses page:


As always, we love when teachers test our courses in these rough versions and let us know about issues, both large and small, that they see. There truly is nothing like having lots of eyes on a curriculum to help remove the bugs. We plan on finishing the Beta version by Winter break and then begin on the answer key and videos. We hope to be able to sell books and answer key subscriptions in late March of 2017.

Finally, we are now in the middle of conference season. I’ve presented now up in Albany, down in Rye Brook, and soon in New York City. This week alone I will be flying out to Phoenix, Arizona, then back on a red-eye in order to present down in Hunter College to AMTNYC. By the time Thanksgiving arrives, I’ll just about be ready to sleep for a week. I’m sure many of my teacher friends will be ready as well.

Have a safe and happy Thanksgiving break everyone. Five days off will feel great. May your stomachs be full and your naps long as the days grow short again. Remember, you can always contact me with questions and suggestions at:

eMath September Newsletter

As Labor Day Weekend starts to fade in our rear view mirror and mid-September approaches, it’s time for the monthly eMath Newsletter. I’ve been really busy since mid-August, mostly filling orders, answering lots of questions, and helping folks troubleshoot our new online Answer Key Subscription Service. My apologies for those who had trouble setting up their accounts. As always, email me if you have any issues.

I’ve also been working hard in the last few weeks on the latest round of add-ons that come with our Teacher Plus Subscriptions. I just posted them on the site, so those that have that access (and those that don’t) should go over and check them out. As usual, I wanted to tell you a little about them in the newsletter.

For Common Core Algebra I (our most popular course), we have three/four new selections. We came out with a mid-unit progress quiz for Unit #2. We put up a Form A and Form B for your convenience. We created a worksheet that gives students more practice with linear word problems. This one should definitely be done after you have done Lesson #7 in Unit #2. It’s a really good sheet that can be used as extra credit or just more practice for struggling learners. Finally, we created a small worksheet to prepare kids for inequality work later in Unit #2. This sheet is great for a two year CC Algebra I course where kids have a really hard time comparing two numbers using the greater than and less than operators.

For Common Core Algebra II, I started off with one of my favorites, a Desmos Classroom Activity on Forms of a Line. Students are supposed to come out of Common Core Geometry with some exposure to both the slope-intercept and point-slope form of a line. This Desmos Activity allows students to practice in an interactive way with equations of lines in both forms. It could be used as extra credit, extra practice, or even to replace Unit #3.Lesson #3. Don’t worry if you’ve never done a Classroom Activity on Desmos. I’ve also created a detailed Teacher Direction sheet. Email me if you still have questions.

I’ve also created a mid-unit quiz for Unit #4 of Common Core Algebra II. This is a mammoth unit, so I thought having a quiz that covered the topics from the first seven lessons would be helpful. It’s not a long quiz, but it assesses all of the fundamentals of exponential functions. Finally, I added a brand new lesson to Common Core Algebra II on the asymptotes of exponential and logarithmic functions. The term asymptote does not arise in the Common Core Algebra II PARCC standards, but New York State put it on their June Regents examination in CC Alg II, so I thought it might make sense to have a lesson on these important graphical features. No video, yet!

Finally, Algebra 2 with Trigonometry. I feel like this is sometimes the forgotten child of the three courses. It has been all but phased out in New York State, and, yet, plenty of schools still use our text. We love the course and recognize the important differences and similarities between it and Common Core Algebra II. For this month, I’ve added three new resources for the course. First, I have a full (but somewhat short) Unit #2 Quiz (on linear functions). I also included a Unit #3 Mid-Unit progress quiz. Unit #3 is a long unit on quadratic functions and their algebra, so I thought it appropriate to see what kids know after the first eight lessons. Finally, I included a brand-new lesson in Algebra 2 with Trig on Factoring by Grouping. This lesson was long overdue.

Now that I’ve gotten the add-ons out of the way, let’s talk about Common Core Geometry. I’ve really taken a pause on that since late August. I’ve simply been too busy with running the business and writing the add-ons, but now I should be able to get back to writing it. I’m in the middle of Unit 5 right now (the first four units have been posted) and hope to have it finished by the end of next week. I’ll post all of the first draft pdf files at that point. I’m going to continue to write units and maybe record some videos (just to try out some new tech that I have). My goal is to be done with all lessons and homework sets in first draft form by December winter break. The answer key and videos will take some time as well, but, with some hard work, I will hopefully be done with it all by late winter/early spring. Only then will we have Common Core Geometry subscriptions and workbooks to sell at eMathInstruction.

For those of you already working with the curriculum, I image some will be almost done with Unit #1 soon. Unit #2 in CC Geo is on transformations and many of the lessons involve the use of tracing paper. We create our own because we couldn’t find anything on the market we liked. I’m hoping that by Monday of next week (9/19/16) we will have it on our site for sale. It will come in 50 sheet spiral packs that students can rip sheets from (for $5 each) or in stacks of 500 (for $20 each). Here are a few pictures of the tracing paper:



Finally, a note on  our new software products from Efofex. There’s been a lot of interest in the programs given their ease of use. I was talking to a teacher on the phone about Geometry just a couple of days ago and he was bemoaning how difficult making diagrams for geo can be. Efofex MathPack, one of the packages we sell, makes creating these things so easy that I’m chomping at the bit to get back to writing it all. I just wish the software would have been around back in 2005 when I first started work with the Arlington Algebra Project. Imagine how long this would take using the standards graphics on MS Word?

Right Triangle

And my own least favorite graphs to draw, exponentials:

Shifted Exponential

If you are interested in seeing what the Efofex software can do, try downloading a free 30 day trial of it. No muss, no fuss, and no spam if you decide you don’t like it. It just stops working. If you have any questions about it, don’t hesitate to contact me.

O.k. So, that’s about it for September. I hope that everyone’s school year is starting off well and the temperatures are cooling everywhere (I’m sure Phoenix is still quite hot my Arizona friends). I’ll be working hard on Common Core Geometry and more add-ons in the next month. Tune in for all the updates in the October newsletter. As always, contact me via email if you have questions or suggestions:

Common Core Algebra I – Regression and Residuals Reviews – by Brett Widman

Brett Widman, who contributes a lot of material here on the Forum, has given us another great resource. He created a Common Core Algebra I Review on Regression and Residuals. We don’t have much time left with the kids, but if they are confused about this fairly complex topic (especially for Algebra I students), check out Brett’s review.

As always, thanks Brett!

eMath Website Relaunch

We are really excited at eMathInstruction because we are relaunching our website and, to a certain extent, our business model. I explained lots of it in a previous post:

New Structure – New Products

I thought I’d give a little tour around the site now that it is operational. First, let’s start with what everyone likes, the free stuff. You can now access all of our courses (coming soon Common Core Geometry) from an easy Course link on our main page:

Main Page

If you click on any of the free courses or on the Courses header in the main banner it will take you to our convenient list of contents for each course. Here’s Common Core Algebra II:

CC Alg II Page

That doesn’t look too different from before, although you may notice a lot more content towards the bottom of this list. More on that later. For now, let’s take a look at one of the units. If I click on Unit 12 (Probability) we see:

CC Alg II Prob

All of our content is now here. The lesson, the video, the answer key, the Word files. It’s all sitting here accessible at any time from an Internet connected computer. Super easy.

Now, as always, the PDF lesson and the answer key are still available for free by clicking on either one of them. In fact, if you click on the video, it now simply opens it up in our site as opposed to taking you directly to YouTube. But, look what happens if you lick on anything below the video link:

Sorry Notice

So, we now have yearly subscriptions that allow you access to all of the files at all times. You can find out all sorts of details about the plans, their pricing, and what they include by clicking on our new pricing structure:

eMath Instruction Products and Pricing 2016-2017

By making all of the contents available online, we will be able to give timely updates to answer keys, assessments, reviews, and other materials. One of the many things we are excited about for next year is a feature we call the Add-On. Each month of the academic year for each of the courses, I’ll be releasing some extra resource. One month it could be an assessments. Another month it could be a Project Based Learning Activity. I’m very excited about these because it will allow me to continue to think about Algebra I and Algebra II while I’m busy at work with Geometry.

So, come by the new site, take a look and let us know what you think. Send us questions that you might have regarding the subscriptions or any of our products:

Common Core Algebra II Review Videos – by Kris Williamson

Kris Williamson, from Newfield, has been supplying us with Common Core Algebra II Review videos based off of the unit reviews that I posted to the site a few months ago. We’ve been linking to them as he has supplied them, but now we have the links to all the videos in one post. Just in time for the June 1st exam.

Thanks Kris!!!
