DO NOT OPEN THIS MATH BOOK Review

This is a walk through and review of "DO NOT OPEN THIS MATH BOOK" by Danica McKellar. My eight year old wanted to give a review and show other kids this book. He really enjoyed the games and activities and is currently working through McKellar's "The Times Machine" which features multiplication and division. All comments are his own, and please be kind!
