Extending this activity

  • -Once home, record all the possible combinations of rocks inside and outside the circle. To do this, draw circles on paper. Show the first circle with all five rocks in the circle. The next circle, show four rocks in and one rock out. Continue this pattern all the way to zero rocks in the circle and five rocks outside the circle. There should be six different combinations.

    -Read “12 Ways to get to 11” by Eve Merriam and explore all the different combinations of making the number eleven.

Adjust for an older child

For a more challenging game, use ten rocks. Use a number sentence each time to describe how many are 'inside' and 'outside' the circle. For example, “I have seven rocks inside my circle and three rocks outside my circle. Seven plus three is ten.”

Adjust for a younger child

To ensure success of getting some rocks inside the circle, have the child move up closer.
