To play the game students need number cards 2-10. Students pick a card out of the pile and put it in the whole box. Students then take out 2 from the number and need to find the missing part. Afterwards they need to come up with 2 addition sentences and 2 subtraction sentences to match the number bond. The game can be more challenging by having students take out other numbers as a part or using higher number cards. Place the worksheet in a clear plastic sheet protector and have students play with dry erase markers.
