In looking for some fun activities surrounding eating well, I found the USDA website for 'my pyramid', the apparently new way to determine what you need to eat. They have free kits for educators, etc, and I have the link here if you are interested. I signed up for a Level 1 (grades 1 and 2) kit and some poster handouts. There will be 25 posters, which I will be happy to share when they arrive.
