The Meaning of the Equals Sign - First Grade Math

My students are learning that the equal sign doesn't always occur at the end of an equation. Once they get that each side of the equal sign must be equal, they are on their way. It might seem like a simple concept, but many have only seen an equation with the equal sign at the end. I am starting out with manipulatives and a balance to demonstrate this concept. I am still in the process of completing the unit.

I'm always looking for a book to connect to my math concepts.  Have you read Equal Shmequal by Virginia Kroll? Do you have any favorite books to use in this unit?
