Each strip is a unique puzzle that contains 4 quadratic expressions in both standard form and factored form, including difference of squares and trinomials (a=1 and a>1). I have my students cut the squares out and match the standard form and the factored form of the same quadratic together, and make those sides of the tiles touch. When they have all 4 expressions paired up, they should have a 2X2 square. I have my students glue all 4 tiles in order in the 2X2 grid provided. Students can work on this individually or in pairs to reinforce their factoring knowledge.
