This book encourages children to master their times tables though understanding rather than memorization. By learning to group numbers in smart ways, kids can learn to multiply numbers of any size quickly and easily in their heads. Traditional multiplication and division algorithms follow naturally from this approach as kids develop the thinking skills they'll need for higher math.

This sequel to The Grapes of Math challenges kids to master important problem-solving strategies. Like sports and music, being good at math requires practice, lots of practice! This book encourages flexible and creative thinking, and continues to develop math intuition and fluency with numbers. Most importantly, it makes math fun and challenging for kids. A favorite of many students and teachers.

Math and art history? Of course! This book introduces an important concept in probability - combinations and permutations - with the goal of teaching children to be more systematic in their approach to problem-solving. Kids will learn to think about numbers in terms of other numbers, and get much needed computational practice making sums up to 10. Math-terpieces offers lessons in art history while introducing famous works of art including paintings by Monet, Cezanne, Picasso, and Pollock.

These whimsical math stories give young learners a head start on the road to higher math. They not only teach children to count, but more importantly, they teach kids to break numbers into smaller pieces - the secret to being good at math.
