In this game there are cards with gold coins and an addition or subtraction problem. There are other cards with a rainbow and pot of gold with answers. There are multiple answers that are the same, so this wouldn't work well as a memory match game. I have gold coins I have purchased for cheap from a party store that my students use as manipulatives to solve the problems with, and then search for a matching answer card. They love it!
