Take a large sheet of white butcher’s paper and lay it on a flat surface. We chose to take tables and lay them on the floor because the room was carpeted.
Pair up children so they can draw their partner out onto the paper.
After each child has been drawn out let them take red and blue markers to draw out the circulatory system down each leg, arm and one line going to the brain. Add a heart in the middle and have the lines connect to the heart the way the veins would. The lines should look similar to this:
When they are finished take the red and blue paint and give each child a small amount on a disposable plate. Also give them each a handful of Cheerios. Then let them attach the cheerios to the matching red or blue lines to show how the blood flows from the heart to the different parts of the body.
