Magic square, 9 square puzzle, square puzzle, cut up whatever you call it these are a lot of fun for students. They solve each problem and match them to their corresponding answer to put the cut up square back together.
In this matching square puzzle, students will be practicing factoring trinomials with a>1. However it could also be used to practice multiplying binomials depending on which way you want to approach the problems. I suggest having the students show work on a piece of paper to make sure they are factoring or multiplying (whichever you choose) and not the other way around.
Before class these squares each need cut out.
If you want a puzzle that is factoring trinomials with a=1 see below.
