This book is packed with great information about graphs! Although the book is written as a story (Gonk and Beezy have a contest to see who can make the best graph) the information is communicated clearly.
Gonk and Beezy each make three different types of graphs. This gives kids a great survey of some of the basic varieties they might encounter in elementary math. The appealing pictures and storyline add interest to the lesson. This book would fit in very neatly with units on graphs up to grade 4 or 5. I have to admit, I learned some things about graphs from the "make your own graphs" section at the back of the book!
Loreen Leedy has authored several other books about math concepts, and they are definitely worth a look.
