Xia Xiaowu, a great math teacher from New York City, sent this awesome activity that has kids figure out what the sum and product of a quadratic’s roots are by using the Quadratic Formula. Now, I know that many of you know that sum and product of roots is sort of “on the way out” in terms of content being assessed on both CC Algebra I and Algebra II, but this project is really neat… Read more »

Common Core Algebra I Regents Question Analysis – by the Nottingham Team
Posted onSo, if you’ve been wondering, as I have, how the questions on the New York State Regents break down by standards, this is the Excel sheet for you. This was put together by the awesome team at Nottingham High School, Christopher Desmond, Eric Scriarrino, Nina Gjoncari, and Christine Varley. It is an Excel spreadsheet that lists all of the Common Core Algebra I standards, how many questions of previous Regents exams align to the standard,… Read more »
Linear Versus Exponential – by the Nottingham Team
Posted onSo, the team from Nottingham High School sent me this cool graphic organizer in order to compare and contrast linear and exponential models. This is a huge fluency issue within Common Core Algebra I and this resource really summarizes it nicely. Use it to help kids review at the end of the course! Thanks to Christopher Desmond, Eric Scriarrino, Nina Gjoncari, and Christine Varley for sharing this! Linear vs Exponential
Protected: CC Alg I – Unit 8 – Quadratics Resources and Test – by the Nottingham Team
Posted onNottingham Gold – by Christopher Desmond, Erin Scriarrino, Nina Gjoncari, and Christine Varley
Posted onSo, back in the fall of 1998, I spent 10 awesome weeks teaching at Nottingham High School in the great upstate New York City of Syracuse, probably best known for its college basketball team. But, I tell you, the students and teachers at the Ham provided me with some of the greatest memories of my early days in teaching. Well, recently I’ve had the pleasure of communicating with some of their great teachers again. And,… 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 »
CC Alg I Regents Review #14 by Brett Widman
Posted onSo, one of these days I’m going to put up a post with all of Brett’s Regents Reviews grouped together. This is the second one he’s given all of us in the last week! There are numerous nice problems on this set, including a great system of inequalities word problem. It’s one of my favorites. Consider using this as a nice take home assignment over spring break. Thanks again Brett! Algebra 1 RR#14
CC Algebra I Regents Review #12 – by Brett Widman
Posted onBrett Widman, from West Seneca CS, has given us another great review. You have to check out some of the graphs on this one. Really great work and nice questions. With spring break coming up for many of us (yay!!!) this would be a great take home assignment. Thanks Brett! Algebra 1 RR#12
CC Alg I Version 2.0 Unit 8 Review Mistake – found by Jeremiah Franklin
Posted onHey Everyone, So, I posted a Unit 8 review packet a couple of days ago and my quadratic word problem right at the end lacked a rational solution. My good friend Jeremiah Franklin from Arkport CS caught the mistake. I changed the problem so that now it works out that the width of the path is a rational number (but not an integer). Here’s the update: Unit #8.Quadratic Functions and Their Algebra.Unit Review
