Our long time friend Brett Widman from West Seneca sent us a great review packet on polynomial functions and their corresponding graphs. We have all seen in the sample problems the clear emphasis on the connection between the equations of these polynomials and their zeros. Brett’s problem set does a great job reviewing this. Here it is!!! Algebra 2 Writing Polynomial Equations Thanks Brett for this really great contribution.
So, I’ve made quite a few posts lately because we are near the time when teachers will be working through the very confusing topic of inferential statistics in Common Core Algebra II. With so little guidance from NYSED on the matter, we are left to sift through sample problems, standards, and (ugh!) the Modules. Ultimately, inferential statistics is a topic that is much, much too large to simply squish into Algebra II. If anything, the… Read more »
Well, it’s getting to be crunch time in Common Core Algebra II now that April looms before us. As at Arlington, I’m sure that many districts are beginning Probability soon and will then turn to statistics in Common Core Algebra II. I still am a little in the dark about the expectations that the state has in terms of what it wants students to know and be able to do when it comes to inferential… Read more »
We had a nice contribution this past weekend from Sharon Truland of Sag Harbor Schools. Sharon doesn’t follow my progression in Common Core Algebra II, but volunteered a bunch of unit reviews that I think could still be very helpful regardless of order. Here they are: Unit 1 Review (Polynomial Review) Unit 2 Review (Facotring Reviw) Unit 3 Review (rational Numbers) Unit 4 Review Sheet(Imaginary Numbers) Unit 5 Review (Trig Review) Unit 7 Test Review(Logarithms)… Read more »
So, Michael Desharnais and Giselle Ferraro from Port Chester Schools put together a simply amazing graphing calculator resource guide for the Common Core Algebra exams in New York state. Granted, it is mostly geared towards CC Algebra I calculator skills, but I wouldn’t hesitate for a second to give it to my CC Algebra II kids as well. It has everything in terms of button by button directions. Here’s a good example from statistics. Click… Read more »
A few days ago I posted a really neat activity where kids use the online graphing calculator Desmos to fit 20 polynomial curves based on their zeroes and one additional point. I called it the Great Polynomial Challenge. I made these by creating an image in Desmos, saving it as a GIF file, and then importing it back into Desmos. To be honest, it was a bit of a pain and the results were good,… Read more »
Take the polynomial challenge! Try to come up with as many equations as you can for the 20 polynomial graphs given in 40 minutes of time. Here’s the worksheet: Polynomial Challenge And here are the links to the challenges. Each is a Desmos graph that you can experiment with to find the correct equation. Hyperlinks are also included on the worksheet, but you can get to each challenge here. Polynomial Challenge #1 Polynomial Challenge #2… Read more »
So, I recently had the pleasure of speaking at the NCAMS Winter Luncheon about issues with Common Core Algebra II. I shared work that I had been doing and, of course, had the ubiquitous Power Point presentation as well as other resources. I promised the great Long Island teachers who were attending that I’d put up a post with many of the materials that I showed them. So, here it is. I’m going to try… Read more »
