Happy New Year! We’ve now closed the book (thankfully) on 2021. As 2022 begins, we know the challenges facing teachers, students, and parents are as daunting as they have ever been. As always, we’ve been working hard to create more resources that teachers can use in their classrooms. Before we detail the new resources we’ve added, all of us at eMATHinstruction want to give a huge shout out to all teachers. You are rock stars,… Read more »
I don’t know about anyone else, but it was a long, long day for me. We had 475 students taking the Common Core Algebra II Regents exam for the first time at Arlington High School. The exam started at 8:00 a.m., but I was there at 6:30 along with Dawn Orlik, the head proctor of the exam, to begin setting up for it. All 475 students were in one giant gymnasium for us. The exam… Read more »
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!!!

A few weeks back, I had a post that shared a bunch of great videos that Kris Williamson, from Newfield CSD, that were made based on the CC Alg II Reviews that I posted previously. At the time, Kris had the first five units done, now he has 10 out of 13. I’m posting them here along with the pdf slides that he used to go along with them. Please share these links with your… Read more »
Elaine Perkins of Elmira High School, upstate in the Southern Tier, just sent us an awesome synopsis of the material in Common Core Algebra II. This isn’t a review set of problems, but a comprehensive listing of all of the content with important formulas and other ideas. Elaine was kind enough to supply the document, which must have taken her weeks to create. She gave it to use in MS Word. So, teachers can decide… Read more »
Kris Williamson, from the Newfield Central School District, has given us a great contribution heading into the homestretch in Common Core Algebra II. He essentially took the Unit Reviews that I created, sliced and diced them, and created videos of all the reviews. Kris is relatively new to the video world, but he’s done a really nice job. I’m going to let him explain it to you… “Hello! I am using Kirk’s Algebra 2 Lessons… Read more »
Recently my good friend Joey Shavelle of Jolo Studios put some additional functionality into two of our statistical simulators. For the sample mean simulator he added code that calculates the mean of the means and the standard deviation of the means. Here’s what it looks like when I had a population mean of 127, a standard deviation of 32, and a sample size of 50 with 1000 simulations: (Click on the image to see it… Read more »
A few weeks back, I published three new lessons to go with our final unit in Common Core Algebra II – Statistics. These lessons extended the work that we began in inferential statistics by introducing more formal ways of finding variation within sample statistics, such as sample means and proportions. By continuing to use simulation, we introduce students to the Central Limit Theorem for both sample means and sample proportions and extend this to a… Read more »
As many of you know eMATHinstruction offers online apps for performing the statistical simulations required in Common Core Algebra II. You can find links to those simulators at this post of mine: Statistical Simulations and Inferential Statistics – by Kirk The simulators work like a charm and I explain how to use them as well as how to use our TI based calculator programs in this YouTube video: YouTube – Statistical Simulation Programs from eMATHinstruction… Read more »
