This is a set of 72 perfect square trinomial factoring flash cards. These can be assembled the same way my trinomial flash cards can be set up: print on cardstock, laminate, cut, hole punch, and binder ring!
This serves as an amazing set (along with the differences of squares flash cards) in reviewing how to factor. The answer key is directly on the back of each card. Enjoy!
I will very likely add to this bundle. When I update it and add more cards, you will be notified!
