On a recent vacation I had to find some fun for my munchkins for the car ride. So we pulled out some stickers, and I started calling out body parts. Their job was to stick the sticker to the correct body part. My toddler loved practicing and my preschooler loved passing out stickers and peeling them from the sheets. This game lasted a good 30 minutes and they were (delightfully) covered from head to toe...literally. It was also a fun and easy way for me to see which body parts I needed to work on. It also gave us a learning opportunity, like learning clavicle, shins, knuckles, and other parts.
This could also work in a grocery store, waiting for food in a restaurant, a doctor's office, or just about anywhere you need to divert some attention for a little while.
