This was very short and simple, illustrating basic whole number mathematics. It's probably most appropriate for elementary students, although I will be keeping it in my classroom for those middle schoolers who still struggle with adding and subtracting whole numbers. For those who simply need a more entertaining text to capture their math interest, I will be checking out the rest of this series.

I chose this book for my Picture Books as Sequential Art class because as I was reading a post from the Good Comics for Kids blog (ALA: A random walk through the exhibit floor) I was putting different books on hold at the library to take a look at and I skipped over the mention of this series, quickly dismissing it.

I read this book because in class we had to read a graphic novel. At first I thought I would hate graphic novels because they are a book genre.

I suggest this book to all ages because it is a very easy read.

I teach reading and math and so I loved being able to do some reading in my math classes and was further encouraged that (being a graphic novel) the kids were just as enthusiastic about it - most of them at least.

Another graphic novel about bullies. The graphics are good and the story follows along well. Interwoven are math concepts of whole numbers. This book would be suitable for elementary students.
