So, the other day I said I was sharing my last set of INB pages from last year. Apparently, I totally forgot about the existence of polynomials and radicals. Oops! So, let's tackle polynomials today.

Polynomials started with a unit divider. The front has a place for students to reflect on the top ten things to remember from that unit.

The back has a list of SBG skills and a place for students to record their scores.

We kicked off polynomials with a Frayer model.

Next, we did some coloring as we practiced applying the definition of a polynomial.

If the expression was a polynomial, students colored it. If it was not a polynomial, they had to explain why.

Up next: naming polynomials!

I like this practice sheet because after I make up the first few polynomials to name, students usually suggest their own polynomials for the rest of the class to name!

I added a new INB page this year to remind students what the requirements are for a polynomial to be in standard form.

Then, we practiced taking polynomial expressions and writing them in standard form.

I was a bit overambitious about how many examples we were going to get through...

Adding and Subtracting Polynomials

Multiplying Polynomials. Guys, I cheated on the "Box Method" this year with the "Grid Method." But, I promise it's the exact same thing. It just seemed to tie better to what we had been doing with multiplying polynomials with algebra tiles.

I also let students choose whether they wanted to use the distributive property or the grid method. In the past, I always forced students to use the box method. But, now I'm starting to think that forcing students to use "my method" isn't really what teaching math should be about. Still, it broke my heart every time I student chose to solely use the distributive property and made lots of mistakes that would have been prevented by using the other method :( How do you find a balance between giving students autonomy and setting students up for success with a tried and true method...

Factoring out the GCF of a Polynomial

Factoring Quadratics. I had to make a lot of compromises with this topic that made me sad. But, I just didn't have the time I usually have for this topic. Oklahoma standards only require Algebra 1 students to factor quadratics with a leading coefficient of 1. Usually, I go above and beyond the standards and have students factor quadratics with other leading coefficients. This means that students really need to use the box method. This year, I only did what the standards required due to time constraints. This meant that students didn't really see the benefit of using the box/grid method to factor quadratics. I personally think it's a mistake to set up the standards this way, but I'm not the one in charge.

Files for these notebook pages are uploaded here.

Can you post a link to the unit divider? I really like the top ten list!

ReplyDeleteWould you consider posting INB pages for all units? Your pages are awesome and l love how your notebook is set up but I wish I could see more of how it's organized and the pages for other units. Your stuff is amazing!

ReplyDeleteThese are great. I've used your "naming" pages for a few years and my students have loved them. I too would love copies of these. Have you checked out the Polynomial Puzzlers on NCTM Illuminations? Good activity for this unit.
