Shark Swimathon

(4) K-3 MathStart series. Illustrated by Lynne Cravath. The Ocean City swim team--six sharks clad in brightly colored bathing suits--struggle to complete enough laps to earn money for swim camp. The question, "Why do sharks have trouble swimming?" may cross some readers' minds. However, the math story does neatly weave in real-life applications of tallying totals and subtracting two-digit numbers. Related activities and examples of different subtraction strategies are included.
