Players each take two counters/ dried peas. Take it in turns to throw your counters onto the mat.
Add the two numbers together. Take this total away from the total, and write down your new score. Then the next player has their turn. The winner is the first person who reaches 0. If your counter rolls off the board, you score 0.
For example: your teacher may set your total at 30, or 100, or may change the board to make it harder!
