We are big fans of Usborne books, so when I saw this one on Amazon for below retail I was thrilled to get it for my little self-described "mathetarians". I have two children ages 5 and 7 who love to practice their times tables and read on a 2nd and 3rd grade level. This book is perfect for them (I would say 2nd-3rd grade reading level and up). The flaps are sturdy and well constructed and add humor and detail to the story. While this book would not be the only method I would use to teach multiplication, it is an excellent additional resource to any home library for families with elementary aged children.
