Have you re-checked your polynomials word splash recently to write down what you know about new vocabulary?

I would rotate it if I could :-).

We brainstormed as a class and wrote down our ideas about WHAT LIKE TERMS ARE....do you have your notes?
If you want to practice combining like terms (adding) try using the garden perimeter sheets again (print off the last 2 pages only).

We used algebra manipulatives to add and subract polynomials on the first try, here is the activity we did to start adding and subtracting.


We had a mastery assessment on January 17th, in which students practiced collecting like terms, adding and subtracting.  They kept working on it until they got 100%!  Here is a copy of it if you need to try it again (thanks Mr. Bannatyne!).


Quiz #2 on adding, subtracting and substitution/evaluation is on Tuesday, January 25.

Multiplying and Dividing assignments were posted in class.
