Lois Ehlert uses nine basic shapes (square, rectangle, triangle, circle, diamond, half circle, oval, heart, and teardrop) to form a book full of animals. Each animal is accompanied by a short rhyme. Some of the rhymes are good, but some are just terrible. (Ugly bugs get no hugs)This is definitely not one of my favorite Ehlert books. It might even be a bit overwhelming for young children. The rhymes are so short that they don't have any time to even think about the different animals. I could see throwing out the nine shapes to the kids and letting them make their own animals and rhymes though. That would be fun. So, maybe I'd share a few of the animals and rhymes from the book instead of all of them before letting the kids loose on the activity.
