The car drives away and suddenly it’s just Hector the cat and three clever hamsters: Pipsqueak, Chuckles and Moe. The hamster champs offer to show Hector their new stunt, which requires they leave the safety of their cage, but only if Hector promises not to chase them. “All right,” he says, “But if I get bored…watch out!” Using a protractor to measure a 30-degree angle, the hamsters set up a ramp made out of a board supported by blocks. Then they get in a toy car, parked on the couch, and race down another ramp—this one made of pillows—which gives them enough speed to climb up the board and briefly fly in the air. Wheee! Hector’s not impressed. So they try again with a 45-degree angle. Then a 60-degree angle, but it's too steep. Hector’s getting bored! He wants a larger angle. Guess what happens when the champs try a 180-degree angle?

Learning about angles helps children identify and describe different geometric shapes.
