This game is an unknown addends game (2+3=1+?) that I use in my first grade classroom. It is absolutely great as a review game or as a math tub. I put the board in a sheet protector and laminate the cards. Students pull a card from a paper bag and solve the problem as a table or individually. Students write the answer on the board and try to fill up as many squares as possible. I also included some cards that say "bang" in case you want to plan bang style where students loose a turn if they pull that card.
This game comes with 26 different unknown addends problems that will keep your students busy!
