内容简介
Gr. 2-4. Like other books in the MathStart series, this presents a mathematical concept in the framework of a story. Here, a shark swim team practices subtraction of two-digit numbers as it tries to reach a goal of 75 laps. The focus is on the subtraction, which gets progressively more difficult as the predictable story goes on. Swordfish Coach Blue explains the process in each example. Perceptive children will note that the swimmers' performance improves with practice and that one shark uses division to determine the number of laps each teammate must still swim. Lynne Cravath's illustrations, in swimming-pool hues, feature amusing details and an interesting assortment of sharks, from twin hammerheads to Tiny, the hair-bowed whale shark. An appendix suggests activities to extend the lesson and includes a list of other books with a subtraction theme. Sharks, sports, and subtraction--a winning combination. Catherine Andronik
