Using either number cards or tens frame cards students can play Go Fish or a War type game. Cards can also be used for small group instruction to work on counting on, counting back, etc. Two sets of cards are included. One set (0-20) includes fish images on them to help students describe their card if they do not recognize the number as well as to work on positions (on top of, below, etc.). Another set of cards contains tens frames horizontally to work on counting objects in a set.
