This is one of those things all kids just really dig.
Have them lay down on a large roll of paper and trace around them...the ensueing tickles and giggles are hilarious for all. It's a great opportunity to talk about our bodies, it's parts and what they are for. Hand the kids some markers, stamps, sticker, glitter or in our case paint and let them go at it. The best part is it's a fairly big canvas to paint, it takes a while and captures their attention longer than the typical 3 minute child attention span...just got to police the inevitable painted toes hands and maybe even bellies. Try it!
