Doggy Bone Subtraction Match is a game that allows students to practice math facts within 20. This repetitive practice builds fluency. Students match the doggy number card to the correct doggy bone subtraction problem. This game can be made into a file folder game, which allows for arranging the bones in a sequential or random order. The bones can also be left on the sheet as they are and used this way.
This set includes thirteen sheets of doggy bones, subtracting from numbers 8-20. It also includes thirteen sheets of doggy number cards. The numbers on the doggy number cards have been color coded to help students keep sets of cards together, but because of the way the problems were created, all of the sheets have the same numbers on them.
