Algebra 2 Unit 3 was all about solving quadratic equations. Originally, I had planned to make it about solving quadratics, polynomials, exponentials, and logarithms. But, I found that it was smarter to cover solving logarithmic equations at the same time that I taught logarithms, etc. I really should have broken Algebra 2 up into smaller units this year. So, all we needed to focus on for Unit 3 was Quadratics.

Links to download these notebook pages are at the bottom of the post. Enjoy!

The solving by graphing page and the completing the square foldable at the end are new this year. The other pages have been posted before with slightly less color coding.

I used the same equations from the factoring page so students could (hopefully!) make the connection between finding x-intercepts and finding solutions.

Completing the Square Booklet Foldable:

I gave students four of their own problems to work on the inside of the foldable.

Can you share how you explained the "picture" box in the completing the square notes?
