First draw chalk shapes in different colors and have the kids help color them in.
Start calling out directions!
Stand on the heart, jump on the circle, spin on the diamond!!
My almost 4 year old REALLY got into it!
Maybe it was the cape!
Make it easier or harder by changing the directions! For my 2 year old daughter I am just going to see if she can stand on the shape I call out. For my 3 older boys(4,5, and 6) I called the directions out and they had to keep doing it until I told them a new direction. Like keep hopping on the shape till I tell you to run to the heart
