Puzzle: Factoring Trinomials

Factoring Puzzle

My high school class ended the year with a review of multiplying and factoring simple polynomials. We played this matching game, and then I gave them a puzzle worksheet. I liked this idea, but I didn’t like the decoded answer. In my opinion, puzzles should give the student a “reward” for solving them — maybe a joke or riddle or something — but that answer seemed almost like nagging.

So I changed things around to make my own version:

April Math Calendar

My homeschool co-op classes had a lot of fun creating this April calendar to hand out at our end-of-semester party on Friday.
