A modern twist on classic flash cards. In the card set are 36 cards that have polynomial equations and 36 cards have matching polynomial equations that have the GCF factored out in front . How fast can you match the 72 cards.On the back of each the cards is a letter(key), when you are done matching, flip over your pairs to see how many you got correct.In my class we have a time to beat, each incorrect pair adds an amount of penalty to your time.
