A couple weeks ago we used The Foot Book to learn about antonyms. I got the main idea from Mrs. Carroll and the posters idea from Ms. M. The children traced their own feet, or a partners feet, and wrote/illustrated a pair of antonyms on their feet. It was a lot of fun, and the kids had a great time!
I let them decide where to put their feet, which is why there are two random pairs in the big toe. :)
