This is a standards based card game for students learning/reviewing the standard NBT.2.8 - Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
Cut and laminate each game card. Students will have the cards upside down in a pile. You can sort them by add/subtract, 10’s and 100, or any way you choose. Students will draw a card from the number pile. Then, they will draw a card from the operation pile (+/-). Last, have students grab a card from the 10 or 100’s pile. They will have to solve the problem on a white board or paper! Great for review!
