A funny, smart and delightfully original way to teach kids about units of measurement. When Supersaurus claims to be the longest animal, Blue Whale begs to differ. Luckily, Inchworm (who happens to be exactly one inch long) offers to measure them both, and they agree the loser will treat the winner to lunch. But after measuring all 1300 inches of Blue Whale, Inchworm doesn’t have time to measure Supersaurus. Centipede (who happens to be exactly one centimeter long) enters the scene and measures Supersaurus at 3302 centimeters. Great! Except centimeters are different units of measurement from inches. Will they ever figure out who won? At the end of this ever-so-long contest of length, kids will love how the winner is revealed!
