This small group activity will help practice the following CCSSM
*2.OA.B.2-Fluently add and subtract within 20 using mental strategies. By the end of Grade 2, know from memory all sums of two one-digit numbers.
*2.NBT.B.5-Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Turn over two marshmallow cards and one mug card to create an equation to solve. If the solution to the problem you created is on the board, cover the solution with your marker. If you can not cover the solution, lose your turn. Your goal is to try to cover all the solution numbers on one mug with your marker color.
This game is designed to be played as a small group activity. Every player should create the equations and solve for solutions to practice adding and subtracting using regrouping methods. You could use different colored (types) of marshmallows to make the activity more fun for the group.
Print one of the boards for the activity. Print 2-3 sets of the number cards and 1 set of the symbol cards.
A B&W copy of the board is included if you would like to have students color their solution choice instead of using markers.
