Wilber, Wendell, Willy, Walter, and Woody really know how to put on a show. Five hilarious ducks juggle pies?SPLAT; spin plates?CRASH; and show off their magic box?WOWEE! Their slapstick routine is also a math lesson. They introduce the concepts greater than, less than, and equal to, as well as addition and subtraction. All the while, students will be laughing so much, they won't even realize that they are learning. A page for teachers and parents explains exactly how the book meets the Common Core State Standards (K.CC. 6-7) and (K.OA. 1-5).
