eMath March 2020 Newsletter

What a crazy last few weeks it has been. School districts have been closing left and right for weeks or even over a month in order to “flatten the curve” as it is being called. We just posted an article detailing the steps we are taking here at eMathInstruction to help districts as many move to a remote instruction model in the coming days. Part of how we are going to help, though, is by continuing to publish materials in our monthly add-ons and by continuing to record videos for our middle school series of courses. Let’s discuss the add-ons first and then I’ll give you an update on our middle school progress.

In Common Core Algebra I Add-Ons this month we have the Unit 8 (Quadratic Functions and Their Algebra) Form D Assessment. We also bring you the Unit 9 (Roots and Irrational Numbers) and the Unit 10 (Statistics) Exit Tickets. We will put out our last CC Algebra I exit tickets, for Unit 11, in April. I’m hoping that teachers might be able to creatively use the exit tickets in a remote learning situation. Maybe they could be used for informal assessment by the student.

For Common Core Geometry Add-Ons this month we have a few resources for Unit 8 (Right Triangle Trigonometry). First we bring you a practice set of exercises on solving for missing sides and missing angles in right triangles using the trigonometric ratios. This is a straight up fluency worksheet that gives students some nice practice setting up trig ratios and then solving them. We also have the Unit 8 Form C Assessment. Finally, we bring you the Unit 9 (Circle Geometry) Exit Tickets.

This month we are brining you a lot of resources in the Common Core Algebra II Add-Ons. CC Algebra II is a very long course, as anyone who has taught it knows. In order to keep pace with the Form D assessments and exit tickets, we bring you five resources in CC Algebra II this month. We begin with the Unit 8 (Radicals and the Quadratic Formula) Form D Assessment. We then have the Unit 9 (Complex Numbers) Exit Tickets. Of course, that means that we then bring you the Unit 9 Form D Assessment. We then have the Unit 10 (Polynomial and Rational Functions) Exit Tickets and Form D Assessment. We wanted to make sure we got all of these resources to you now, so that if you need them while students are learning from home, then you have them at your disposal.

In Algebra 2 with Trigonometry Add-Ons, we have a similar situation to CC Algebra II. In this case, we bring you four resources, starting with the Unit 8 (Trigonometric Algebra) Form C Assessment. We then have the Unit 9 (Trigonometric Applications) Exit Tickets and Form C Assessment. Finally, we also bring you the Unit 10 (Exponential and Logarithmic Functions) Exit Tickets.

We are coming along on our Next Generation aligned middle school courses. For those of you not in New York State, the Next Generation Math Standards are what New York is renaming the Common Core Standards (with slight modifications). We now have our N-Gen Math 6 and N-Gen Math 7 books done in their first editions, with sample copies available in early May. Our N-Gen Math 8 book is not far behind. We are busy also recording videos for all three courses. It looks like by the end of March we will finish all videos for both Math 6 and Math 7. Math 8 videos will be finished by mid-April. We hope that these videos will help with remote learning this year.

We are starting to receive orders for our middle school products. Although we are happy to get the orders, we won’t be able to process them until late June. Let us know if you have any questions by emailing Orders@emathinstruction.com. We will be posting cleaned up version of all of the middle school files in June as well standards alignment documents this summer.

That’s it for now. I hope that everyone out there, teachers, students, administrators, and parents, all stay healthy and sane during these coming weeks. We can do so much for each other in our communities, large and small, that will help our country as a whole defeat the common threat we now face. Take care and be well.

Remote Learning with eMathInstruction

The past week has been interesting and trying.  Recently, we learned of several states that have closed school.  In states such as New York, many schools are now closing for two weeks to over a month.  Please know that we at eMath consider every teacher out there to be a hero. You are likely being asked to prepare to do the impossible, teach students remotely.  We are here to help and support you in any way we can.  We have been getting many questions about how eMathInstruction materials can be used so wanted to send out answers to a few common questions.

Q: Can files be posted?

A: We have several different types of files and will address each independently.

  • Lessons and homework sets that are already available for free download may be reposted though we greatly prefer that you just post the appropriate link to our website.  This will likely be easier for you in the long run.
  • Unit reviews are only available with the purchase of a membership and may be reposted to closed systems only such as Google Classroom
  • Answer keys and assessments are only available with the purchase of a membership.  These are our most sensitive files.  These may only be posted to closed systems inaccessible to the broader internet (such as Google Classroom).  We ask that these most sensitive files be removed from the closed system after they are needed. 

Q: Why can certain documents such as assessments, answer keys only be posted to closed systems?

A: There are several reasons we prohibit the posting of these items to traditional websites and web pages. 

  • The first and most important reason is academic integrity.  Students are quite internet savvy.  Students from outside of your school will find the files you post and use them to cheat.  You would not want your students finding answers on the internet so we ask that you be considerate to teachers and students on the other side of the country.
  • eMath Instruction provides a plethora of files for free.  Unfortunately we cannot provide everything for free or we would not have the funding to continue to provide new resources.  If our paid content is posted to the internet where anyone can find it we lose out on the ability to sell our material and therefore continue to do what we do.

Q: How can videos be easily accessed?  Can they be downloaded?

A: All of our videos are on YouTube.  Videos for Algebra I, Geometry and Algebra II are also on TeacherTube.  Unfortunately the file size of videos is quite large and impractical to provide off of the internet.  We understand that many folks struggle with access to internet due to living in a remote location or due to other family circumstances.  At this point, in order to view videos, access to the internet is needed.  Below are the links to our YouTube and TeacherTube channels.  Videos are also accessible from our website.

Q: Can we still purchase books?  How can we get them to students if our school has already closed?

A: Yes.  We have books available.  We can work with your school to possibly ship books directly to students if needed.  Please contact us directly to discuss.  If your school has not yet closed and you think you may need books, your best bet is to order them as soon as possible. 

If there are any other questions you have or any other way we can support you, please feel free to reach out to us.  You can reach us at orders@emathinstruction.com or info@emathinstruction.com.  We are here for you.  We hope you all stay safe and healthy.

Reordering N-Gen Math™ 8 and Middle School Videos

We’ve been getting great input this year on our new middle school courses that are aligned to the new Next Generation Math Standards (coming next year to New York K-8). I’ve had some great conversations with teachers who are using the courses. One of the things I heard from multiple teachers was that they would like to see algebra moved to the beginning of N-Gen Math™ 8 so that equation solving could be a greater part of the geometry units.

One of the new skills that students learn in 8th grade algebra is how to solve equations with variables on both sides. Since our original ordering had this skill taught in Unit 4, we didn’t incorporate it into our Units 1 through 3 (on geometry). We decided to remedy that and move our algebra unit to Unit 1 and then incorporate those algebraic skills into our geometry units (which became Units 2 through 4). Because of this reordering, we had to remove some problems that had been in the algebra unit, but we were able to beef up the algebra in many of the geometry problems.

We also created some new lessons in geometry based on feedback. We created an additional lesson in the Tools of Geometry on angle terminology associated with parallel lines (alternate interior, exterior, same side, corresponding, etcetera). We added a few lessons in our unit on Transformations. One of these looks at congruent angles formed by parallel lines through the lens of rigid motions. The other lesson comes at the end of the unit and gives students lots of practice using algebra to model geometry problems.

One of the very nice consequences of the reordering is that our unit on similarity now comes immediately before the unit on linear functions and graphs of lines. Given that in 8th grade we justify the slope of a line based on similarity, this flow of topics is much more natural. I think the changes to N-Gen Math™ 8 will make it more complete and will strengthen both the algebra and geometry skills of the students. I’d like to thank Elizabeth Agen of Golding Middle School and Beth Goldberg of Linden Avenue Middle School for the feedback on the order of the topics. I had some very good back and forth discussions with both teachers that really got me to think harder about the best sequence of topics in the course.

We’ve also begun to record and post the videos for the middle school courses. It’s going to take us quite some time to finish them as we can only do so many in a day and there’s other work to be done. My hope is to have them all recorded and posted by next spring. We’ll be recording more videos next week and then will need to take some time off for the fall AMTNYS conference up in Rochester. For now, keep watching as we continue to post the first few units of all three courses.

Regents Live Review 2019

In just two weeks students all around New York State will sit down to take their (Common Core) Algebra I Regents exam. As we’ve done in the past two years, I will be doing a Live Review session for each of the three major high school math Regents exams (Algebra I, Geometry, and Algebra II).

I will be going over questions from past Regents exams. The question packets for each Regents are given below. Fair warning: they are extremely long (around 20 pages each)!!!

Common Core Algebra I Live Review Problems 2019 (pdf)

Common Core Algebra I Live Review Problems 2019 (MS Word)

Common Core Geometry Live Review Problems 2019 (pdf)

Common Core Geometry Live Review Problems 2019 (MS Word)

Common Core Algebra II Live Review Problems 2019 (pdf)

Common Core Algebra II Live Review Problems 2019 (MS Word)

We likely will not make it through the entire packet on any one of the nights. I think it really would take about 5 hours to do a complete review.

The reviews will be shown on YouTube Live (Kirk Weiler Channel) and Instagram Live (follow @emathinstruction). The video will be much better on the YouTube Live platform. We mainly will have Instagram Live going for students to comment (whatever it takes to get them to the review ;-).

Can’t wait to “see” you all there.

eMath May 2019 Newsletter

Wow! Is it May already? Right about now teachers in New York are finishing curriculum and heading for the big push to the New York State Regents exams in mid June. We are here to help with more add-ons and Live reviews in June. Before we get to those, let’s discuss the latest and last round of add-ons for this academic year.

In Common Core Algebra I Add-Ons we bring you the Form C Assessment for Unit 10 (Statistics) and Unit 11 (A Final Look at Functions and Modeling). These two assessments mean that we now have three unit tests per unit in Algebra I. We’ll try to add a fourth next year.

For Common Core Geometry Add-Ons we have an introductory lesson for Unit 10 (Measurement and Modeling) along with Unit 10’s Form B Assessment. To begin, we have created a Lesson 0 for the unit on Rates, Densities, and Conversion Factors. We felt that there was quite a bit of work in this unit on applying concepts like density. This lesson reviews these various ideas early in the unit. Use this for kids who struggle with ratio and rate concepts. Our Form B for Unit 10 now means we have two unit tests per unit in Geometry. More to come.

Common Core Algebra II Add-Ons this month also bring two Form C Assessments. We now have a Unit 12 (Probability) and Unit 13 (Statistics) Form C. It’s especially nice to have more statistics questions for this very challenging unit.

Finally our Algebra 2 with Trigonometry Add-Ons also feature two additional assessments, both Form B. First we have the Unit 12 (Statistics) Form B and then we have our Unit 13 (Sequences and Series) Form B.

Lots of assessments this month!

Now for the fun part. We are yet again holding our YouTube Live and Instagram Live Review sessions this year for the New York State Regents Exams. For each exam we will be going over old Regents test questions for 3 hours. Here’s our schedule for this year:

Algebra I (Algebra 1):  Tuesday, June 18, from 6:00 to 9:00 p.m.

Geometry: Wednesday, June 19, from 6:00 to 9:00 p.m.

Algebra II (or Algebra 2): Thursday, June 20, from 6:00 to 9:00 p.m.

We will be broadcasting on our YouTube Channel (click link) and on our eMathInstruction Instagram Live account. YouTube will be much better quality, although commenting will be allowed on Instagram (only go there if you can stand constant comments from teenagers).

We’ll put out more information in the coming two weeks, including the problem sets we will work through at each of the sessions. For now, have a great Memorial Day weekend!

eMath December 2018 Newsletter

Ah, its the last week of classes here in New York before the big break. Kids and teachers here are restive, but happy that one of the longer break is on the horizon. Just last minute tests, office parties, and school concerts to get through. Maybe our hypercube logo in a Santa hat is just what you need:

Or maybe you also just need that vacation. I know I do.

We’ve got the typical add-ons to discuss but first I wanted to update all of you on the latest timeline for New York State switching to the Next Generation Math Standards. If you are not teaching in New York, you may want to skip to the add-ons. However, if you have been confused about when the Next Generation standards are going to be implemented, read on.

As most teachers in New York know, these standards are very close to the Common Core Standards. But, like many states, the political backlash against those standards, earned or not, has made them untenable, at least in name. The timeline for adoption of these standards, of course, is dictated on when they will be assessed. That timeline has been fairly transparent for quite some time at the K-8 level. Here’s the graphic and link from the NYSED.gov website:

http://www.nysed.gov/curriculum-instruction/next-generation-learning-standards-and-assessment-implementation-timeline

The most important part of this graphic is the final piece (with my horrible highlighting):

At eMath we have been working under the assumption that the changes due to the Next Generation Standards in Algebra I, Geometry, and Algebra II would all go into effect in the Fall of 2020 and then assessed for the first time in June 2021. NYSED hasn’t updated that graphic on their website for quite some time (at least 6 months) and to my knowledge has not made any solid decision. But, NYSED is speaking to math teachers, especially in the form of responding to question from the Association of Math Teachers of New York State (AMTNYS). Here is the relevant question (from AMTNYS) and the reply (from NYSED):

I love the fact that “new” is in quotes. Here is the full document:

2018 AMTNYS Math Questions

So, it looks like at the very earliest the changes at the high school level will be assessed in June of 2022 (which seems like a century away to me). And it seems like that will only be for Algebra I. So, those of you holding your breath for 3 by 3 systems to be taken off the New York State Algebra II Regents exam could be waiting until the 2023-2024 school year. Let that sink in for a minute (or more).That’s five years and countless numbers of Regents exams between now and then.

The upshot of all of this for users of eMathInstruction courses is that we will not introduce these changes to our texts until at least the Fall of 2021. This, of course, is subject to change should NYSED decide to implement changes to the assessments earlier, but that would be disastrous for them.

O.k. Onto the add-ons for the month.

In Common Core Algebra I Add-Ons, we bring you two Form C assessments, one for Unit 5 (Systems of Linear Equations and Inequalities) and one for Unit 6 (Exponents, Exponents, Exponents). We will continue to put our these additional assessments year in and year out since we get a lot of positive feedback on them. Of course, it never hurts to have makeups and alternate exams.

In Common Core Geometry Add-Ons this month we have two sets of practice problems. First, we have a Unit 5 Coordinate Geometry Formula practice sheet. This is a short set of problems that give students a chance to practice what they’ve learned about the three fundamental coordinate geometry formulas (slope, midpoint, and distance). This is a good extra assignment for the average student. For Unit 6 we bring you a nice set of quadrilateral practice problems. These aren’t proofs, just algebraic and numerical problems that ask kids to use facts about the various quadrilaterals they’ve been studying.

For Common Core Algebra II Add-Ons we again bring you two Form C Assessments. We bring you the third version of the Unit Assessment for Unit 5 (Sequences and Series) and the third for Unit 6 (Quadratic Functions and Their Algebra).

Finally, for Algebra 2 with Trigonometry Add-Ons we have an assessment and a practice set of problems. We bring you the Form B Assessment for Unit 6 (Polynomials and Rational Functions). We also have another resource for Unit 7 (The Circular Functions). We created a set of fairly basic trigonometric graphs (no horizontal shifts) and ask the students to create their equations based on either the sine or cosine functions. This is a nice sheet to give kids to practice immediately after they have learned all of the basic sinusoidal graph parameters.

So, in other eMathInstruction news, we will be paying a visit to Edward R. Murrow high school in Brooklyn, New York this spring for our annual school visit. I’m excited to meet the students and teachers at Edward R. Murrow and amaze and awe them with some math that’s more fun than serious. Next month we will have some exciting news regarding new courses coming to eMath just in time for those Next Gen Standards I was talking about before. So, I’ll leave you with this teaser of an image:

Have a great holiday season! Enjoy the break, the rest, your family, and your friends. 2019 here we come!

eMath August 2018 Newsletter

Wow! Is it already August 15th? For those of us living in New York, that generally means we have just over two weeks of summer break left before school begins. How time flies.

Speaking of the waning summer, if your school is still looking to purchase workbooks for this coming school year, make sure to do so as soon as possible. We’ve still got quite a bit of them in stock now, but by next week, the delivery times will start to push past Labor Day weekend. For New York City teachers, we now have all of our workbooks, including Common Core Algebra I in Spanish, on ShopDOE and the FAMIS ordering systems. Find all of the important information using the document below:

eMath Instruction ShopDOE and FAMIS List 2018

Now that the school year is almost upon us, we have new additions to each course. As always, please feel free to send us suggestions about what you would like to see as monthly add-ons to various courses. Always best to catch us with your suggestions at least a month ahead of time. Assessments are always in demand and we have a bunch for you this month.

In our Common Core Algebra I Add-Ons, we bring you a Unit 3 (Functions) Quiz. This quiz goes through Lesson 3 of the unit and we provide you with both a Form A and a Form B version of the quiz. This is the first year of our Common Core Geometry Add-Ons. For the Geometry Add-Ons this year we want to make sure you all have a Form B test for each unit. So, for this month we give you a Unit 1 and Unit 2 Form B assessment. These mirror assessments can be used as makeup for the typical exams or just as replacements.

For our Common Core Algebra II Add-Ons, this month we bring you a Unit 2 Quiz (Also Functions). This quiz should be given after Lesson 3. We provide both a Form A and Form B version of this quiz. In Algebra 2 and Trigonometry Add-Ons, we provide a Unit 1 and Unit 2 Form B quiz. In Alg2/Trig, the first two units are very short, so we did not write full unit assessments for them. Here we provide a Form B for the “quizzes” for each of these units.

This year we are going to have our eye on the changes coming due to the Next Generation Standards in New York State. For those outside of the state (or those out of the loop), New York decided, like many states, to massage the Common Core Standards and given them a less politically charged name (they’ve even taken it off of the NY standardized tests). These standards do not go into effect at the K-8 level until the 2020-2021 school year. They will first be tested at the 3-8 levels in the spring of 2021. Here is a graphic of the timeline:

Here’s a link to that page:

Next Generation Math Standards Implementation Timeline

Now, I get a lot of questions about when we will be incorporating the Next Gen changes into our Alg I/Geo/Alg II series of curricula/books. Well, New York State has been vague, at best, about when the changes will be implemented at the high school level. BUT, if you look at the fine print of the Timeline graphic above, you see:

Two things to note here: (1) NYSED has not yet decided on when these standards will be implemented, so we must assume the status quo in terms of the assessment content and (2) the implementation of the Next Gen standards on tests will not happen before June of 2021.

We plan to really start modifying our high school texts later this academic year and will continue to create lessons that fit these standards as add-ons. We do not plan on actually changing the workbooks until the 2020-2021 academic year. We also hope to release something for kids younger than 9th graders for the Next Gen standards as well. More on that later this year.

That’s it for now. Continue to enjoy the rest of summer. Get out to your local fairs, waterparks, and festivals. As for me, I’m looking forward to taking a long weekend to camp with the kids.

eMath May 2018 Newsletter

Well, Spring has definitely sprung here in the great Northeast. As I sit here massive thundershowers are hitting us. We even have a tornado warning! I grew up in Illinois, where the flat terrain essentially guaranteed that tornadoes were commonplace. But, surrounded by mountains (or large hills as some would insist) here in Red Hook, we don’t tend to see twisters here.

But, enough about the weather (actually I’m going to come back to it eventually). We are heading into the homestretch of the school year. With roughly a month to go before standardized testing sets in, teachers should be heading into full on review mode. To that end, let’s discuss the add-ons for Common Core Algebra I, Common Core Algebra II, and Algebra 2 with Trigonometry. Last year for each of these courses we put out short (10 points each) Unit Review quizzes for each unit. For both CC Algebra II and Alg 2 with Trig we put multiple quizzes out for the longer units as well. We released these quizzes between the April and May add-on rounds from last year.

This year we are releasing the Form B (or makeup) quizzes for all three courses. We organized the quizzes from last year and rereleased them as Form A. We then also released Form B as new content. For each course, both documents, Form A and Form B, contain quizzes for all units. These quizzes will help spot check the students as you conduct unit review. Since Teachers have access to the Word document as well, you have the flexibility to combine quizzes as you like and need to.

We will start up with more add-ons in August! Including add-ons for Geometry.

In other exciting news, eMathInstruction will host Live reviews for the New York State High School Regents exams!!!

Last year we live streamed reviews for CC Algebra I, CC Algebra II, and CC Geometry (in that order). We did this using only Instagram Live, since that was where we thought we could reach the most students. By the time we did our last review, CC Geo, we had over 20k viewers. Granted, some of them probably weren’t students at all and left as soon as they realized it was a big, old geek (me) talking about math, but still! Over 20 thousand unique viewers. Even if 5,000 were students, that would be great.

This year we hope to live stream it on Instagram Live, Facebook Live, and YouTube Live. We still have to work out the details on that. But, the dates and times have been set:

Algebra I Review: Monday, June 11th, 6 until 9 p.m.

Algebra II Review: Wednesday, June 13th, 6 until 9 p.m.

Geometry Review: Monday, June 18th, 6 until 9 p.m.

Kids will be able to tune in via Instagram Live (at least) and have a chance to comment (briefly) at certain times during the video. They will need to follow:

@emathinstruction

 

Last year we streamed to my own personal account (@kirkweiler if you want to see me post pictures of my garden), but this year we are only Instagram Live Feeding to @emathinstruction. Have your students follow that to watch. Once we know how to watch on YouTube Live and Facebook Live we will let people know via Facebook.

Finally, back to the weather! In my experience, many math teachers are weather junkies. We like both the predictable, science side of it as well as its probabilistic nature. A neat website to help you visualize the weather patterns, especially air velocity, is a site called Ventusky.com.

It’s a super cool site where those little streaks you see in the image actually move on the screen relative to the velocity of the wind currents. It is especially impressive when you are looking at a hurricane. Here’s a hurricane like pattern off the coast of Japan (thankfully not an actual hurricane/typhoon).

So, check it out if you have the time. It is a CPU drain, so just keep that in mind and close whatever browser window you use to look at it, either on your computer or phone, once you’re done.

That’s it for me for now. We’ll get back to you all with way more news about the Live events as we get closer. Make sure to announce them to your students so they can have a night before (literally) review. You never know who it might push past the passing line.

eMath April 2018 Newsletter

Well, it’s April 16th, so the weather in New York is now turning sunny and spring is in full tilt with the flowers blooming, the birds singing and …

Actually, I’m just kidding. I woke up to snow this morning. Still, not all is dreary. We are quickly approaching the final stretch of the academic year (you are likely just starting the fourth quarter). We have been busy at eMathInstruction working on a variety of different resources, updating our website, and creating add-ons for the courses. Let’s get right into those.

For Common Core Algebra I Add-Ons this month we have added a quiz and a new lesson. For Unit 10 (Statistics) we have added a Form B mid-unit quiz. Last year we added the original quiz and this year we have a makeup or Form B of the quiz. These are always handy when it comes to students who are absent or even if you want to give Period 1 the Form A and Period 2 the Form B. We always try to make them as similar as possible, while still making the questions unique. For Unit 11 (the final unit) we added Lesson 6.5 on Additional Piecewise Functions work. In this lesson we have piecewise functions that include linear, quadratic, and root functions. I still believe that the idea of piecewise functions is challenging enough so that it should be as basic as possible, i.e. just piecewise linear, but clearly the makers of standardized tests disagree with me as they often will include pieces that are non-linear.

For Common Core Algebra II Add-Ons we bring you two activities centered on the probability and statistics units (Units 12 and 13). For Unit 12 (Probability) we have created a Die Rolling Probability activity. We have the students use the random number simulator on the calculators to simulate rolling two die and summing their rolls. We then have them investigate the empirical versus theoretical probabilities associated with this experiment as well as answer a variety of conditional probability questions. There is no associated homework with this activity. In Unit 13 (Statistics) we created Lesson 4.5 on Sampling a Population. We created a data set of 200 values that students then randomly sample from. Students calculate sample means and standard deviations from their samples and then compare these to the population statistics. Like the Die Rolling Activity, this lesson has no homework associated with it.

In our Algebra 2 with Trigonometry Add-Ons this month we have a quiz and another lesson. For Unit 10 (Exponential and Logarithmic Functions) we offer up a mid-unit quiz that covers all of the content through Lesson #6 (Graphing Basic Logarithms). In Unit 11 (Probability) we created Lesson 7.5 on More Binomial Probability Practice. In this lesson we use the calculator to find binomial probabilities and cumulative binomial probabilities for a variety of applied problems.

In other exciting news, eMathInstruction will be at the national NCTM conference next week!!!

We will have a booth set up where you can come and chat and we will also be presenting on Friday afternoon. Drop by and say hi if you are at the conference.

In Geometry news, Version 2.0 of our workbook is now for sale. This new book has the Unit Reviews now included at the end of each unit, so its quite a bit longer than the original book. We’ll begin to add-on to this course starting in August. As always, if you have suggestions in terms of what you’d like us to add, please reach out (make up tests, mid-unit quizzes, extra problem sets, extra lessons).

We’ve been doing some major behind the scenes work on our website recently. We added a second server which does two things for us. First, if the primary server were ever to “crash” then the second server would keep the site up and running. But, even better, the second server allows us to “load balance” the traffic to the site. Hopefully this means shorter page and download times. Now, with all major website work, there are always hiccups in the system. Most of you probably have not had any trouble, but some of you, when trying to go to our main site, have experienced errors such as a “failure to redirect” or “emathinstruction.com” sent an invalid response or even scary messages like “corrupted content error.” I’ll be honest, I don’t really understand what’s happening. But, apparently a one-time fix of clearing the computer’s cache gets the job done. How to clear cache is very browser dependent (Chrome, Firefox, Edge, Internet Explorer, Safari …). The University of Wisconsin (go Badgers) has an awesome site with links to every major browser and operating system:

How to Clear Web Browser Cache (University of Wisconsin)

You know cache is the issue if you can get to our site through one browser but not through another one.

Have a great rest of your April. I hope that spring has arrive for you soon, if it hasn’t already shown up (no sign yet here).
