Jump, Kangaroo, Jump! (Fractions): It's Field Day at camp. The 12 campers—a kookaburra, an emu, two platypuses, three koalas, four dingoes and Kangaroo—can't wait for the games to start. The group divides into halves, then thirds and finally fourths to make equal-sized teams (6, 4 and 3 each) for the big competitions. But it's each camper for himself in the long jump, which is Kangaroo's personal favorite. Seeing the relationship between division and fractions is an important step in understanding fractions.
