The follow-up to the beloved Grapes of Math and Math Appeal books, Greg Tang has come up with another set of riddles to help kids learn common sense strategies for solving math problems. Math Potatoes emphasizes three strategies: making math sums that are easy to work with (such as 10 and 15), to patterns and symmetry, and to look for groups of equal size to multiply instead of add. Helping kids to think about math creatively--in effective, engaging ways-short, illustrated riddles teach kids strategies rather than simple counting. Hardcover with dust jacket. Grades 1-4. Answer key with reduced riddles and explanations are included.
