Subtraction Smash is a fun, hands on way to practice subtraction. Children can either use these cards with your favorite modeling clay/rainbow dough, or can use the cards provided to “smash.”
To play, children make the rainbow dough into balls and place them on top of the dough balls on the cards. The children then “smash” the rainbow dough to complete the equation. They can then record their thinking on the practice pages. If you do not want to use rainbow dough, you can use the “smash” squares to cover up the balls on the cards.
