This file includes 26 blue playing cards with un-simplified numeric and algebraic expressions and 26 maroon playing cards that include the simplified answers. This can be used as a sort, as a memory game, or as "Go Fish." This task reinforces the properties of exponents. There is a free download that goes along with this purchase called: Exponent Matching Card Box. This would be a great addition to math centers or to keep in the classroom for early finishers.
