Collect three different sized heart shaped cookies cutters. Take three small paper plates and put different colors of
paint on each plate. Assign a heart to each plate.
Have the children dip the cookie cutter into the paint and stamp hearts.
As they do talk about the different sizes of hearts. Use the terms small, medium, and large. If they don't
discover it themselves, show them that a medium heart can fit into a small and a small can fit into a medium
sized heart.
Extend the activity by counting the number of each size of hearts.
