Math riddles invite children to discover patterns and strategies for adding at a glance, instead of having to count objects pictured one by one. This is a younger book than last season's winner, The Grapes of Math. While each riddle is explained with a niffty solution, we hope readers will note that there is more than one way to solve each of the riddles. While the underlying idea here is to promote open-ended thinking, the answers in the back of the book may in fact get in the way of flexible thinking. We suggest looking for another way to get the answers other than the one offered by the author.
