A fun, hands-on board game to play in groups when learning to solve subtraction equations that require regrouping.

Students take turns rolling the die and moving around the game board. The number they land on is the minuend of a subtraction equation. They then spin the tens spinner and the ones spinner to form a number. This is the subtrahend of the equation. Base 10 blocks are placed on the Trading Mat, and the student moves the blocks around, making sure they trade tens for ones as required.

The first person to land on the ‘You Win’ square is the winner.
