Teach Your Child the Multiplication Tables: Fast, Fun & Easy with Dazzling Patterns, Grids & Tricks!
Teach Your Child the Multiplication Tables is everything I think a  multiplication workbook should be, and my daughter thinks it's lots of fun.  Set around a circus theme, the books is child-friendly with lots of  pictures, large print and plenty of space for writing the answers. The best  part of this book, however, is that rote memorization is not the goal,  rather understanding the inherent patterns is. My daughter works through  this workbook at her own pace, whenever she's in the mood for it, and she's  already had quite a few "ah-ha!" moments as she recognizes and predicts the  various patterns. --California Homeschool News, December 2006
