You'll Need

  • 19 small objects such as raisins, nuts or jellybeans

Explain that you can use subtraction to compare. Divide the 19 small objects into two uneven groups. Have your child compare the groups to find out which group has more. She can then use subtraction to find the exact difference between the two groups.
