Title: Not worth it.
Review: The book does use chocolate bars to model the use of arrays for multiplication. However, the concept is clouded by the tangental reference to different artistic styles used to write the numbers. At times I thought I was reading an art book instead of a math book. The additional information detracts rather than enhances the concept of multiplication. There are better texts than this one to help with multiplication.
