I found the book perfect square by Michael Hall, while I was shopping at Cover to Cover recently. The cover popped and I couldn't wait to see what was inside. This is the story of a square that is "perfectly happy". Each day the square is altered in some way but instead of being sad about the changes the square decided to make the most of the situation. The text is simple yet powerful; the illustrations are beautiful. I can see using this story when the kids are learning about shapes, as a mentor for writing and also in an imagination center.
