Bring the fun of the classic card games "Go Fish" and "Old Maid" into your Mathematics classroom. This set of cards has linear, radical, and rational functions. Students are to practice finding the inverse of the functions to match the function and its inverse. The rules for both games are included. Both games can be played with the same set of cards. The cards are typed with the function at both the top and the bottom of the cards so students seated across from each other can easily read the cards. This game can increase student engagement, collaboration, and enthusiasm.
