Learning about Fractions from Klondike and Snow

When a polar bear gives birth to two tiny cubs at the Denver Zoo and then abandons them, the zoo staff must raise the cubs. Young readers follow Klondike and Snow as they grow from fragile newborns to large, lively bears, learning about fractions along the way.

5.NF.A.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
