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,… Read more »

eMath April Newsletter
Posted onSpring 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… Read more »
eMath March Newsletter
Posted onIt’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.… Read more »
eMath February Newsletter
Posted onWe’ve now moved past the mid-winter point (Groundhog’s Day) and are heading towards spring, even though our recent blizzards don’t make it seem that way. We’ve got some add-ons and some news here at eMATHinstruction, so let’s get to it. For this month’s Common Core Algebra I Add-Ons we have three new additions. We start with a worksheet that gives students extra practice simplifying square roots. This is a nice worksheet if you just feel… Read more »
Common Core Geometry Beta Version Finished – by Kirk
Posted onThe first version of Common Core Geometry is now done and completely posted. It consists of 10 total units: The total text is now at 95 lessons with homework sets. I’m always happy if a curriculum is somewhere between 100 and 110 lessons. I’ve found over the span of my career that in a 185 day school year, the 100 lesson count is a good benchmark given all sorts of extra days needed for reinforcement,… Read more »
eMath October Newsletter
Posted onHere in the great Northeast, the leaves have changed and the days are getting colder. Since I last wrote, I’ve been hard at work on Common Core Geometry and the latest round of add-ons. Speaking of which, we just put them up on the site. Remember, links to them are at the bottom of each course page. You can also click on any of the blue links below to be taken directly to the add-on pages.… Read more »
eMath September Newsletter
Posted onAs 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… Read more »
Common Core Geometry – by Kirk
Posted onSo, the summer has been a great mix of working on Add-Ons for the three courses we currently offer and thinking a lot about Common Core Geometry. I’ve now completed the first four units and a rough course outline that’s been indexed to the CCSS Standards for CC Geometry (as defined by PARCC and refined by NYSED). I’ve got all of the lessons for those four units posted at this point under our Courses section:… Read more »
Common Core Geometry – by Kirk
Posted onThe summer has begun and so I have begun my work in earnest on eMATHinstruction’s Common Core Geometry. I have wanted to write a text on Geometry for about as long as I could remember, but things just kept getting in my way (kids, teaching, algebra… you know, life). Geometry is an interesting subject that has been studied for almost 3,000 years. Let that one sink in. Three thousand. Euclid’s Elements is regarded as one… Read more »
Area of a Circle – by Kevin Hoang
Posted onSo, a friend of ours from the great state of California, Kevin Hoang, sent this really neat Geogebra demonstration that a student made. It shows the classic slicing up of a circle into sectors and then rearranging them into a parallelogram like figure. This is an amazing demo if you are exploring informal limit ideas in Common Core Geometry (yes I went there) to derive classic measurement formulas. Thanks Kevin! Area of a Circle in… Read more »
