You will need:

  • paper

  • pencils or markers.

Instructions

  • Write the numbers 1-10 (or 1-20) along the top of your paper.

  • Record your starting number (we used 100 but you can change the starting number to any number you like).

  • Player 1 chooses a divisor that will result in leftovers (remainders).

    • Player 1 works out the solution to their problem (in this case, Barbara worked out 100/7).

    • Player 1 collects the leftovers (remainders) as points.

    • The chosen number (in this case, 7) is crossed off the list of options.

    • A new starting number is determined by subtracting the leftovers from the previous starting number (e.g. 100 - 2 = 98).

  • Play continues until there are no more moves that can be made.

  • The winner is the person with the most leftovers.
