Comparing decimals made easy: is 0.25 bigger than 0.5? Line up the dots and see why the longer number isn't always bigger. Lots of children think 0.25 is bigger than 0.5, because 25 is bigger than 5. Sam thinks so too, until a balance and some weight blocks show him otherwise. Adding a zero after the dot makes the numbers the same length: 0.50 against 0.25 is 50 against 25. For ages 8–10. In this video: 0:00 Two parcels: which is heavier? 0:44 Weight blocks: tenths and hundredths 1:33 Sam's zeros 1:47 A zero after the dot changes nothing 2:24 Your turn: 0.3 or 0.29? 2:49 A tricky one: 0.7 or 0.698 3:29 The rule: line up the dots 3:42 Sam's swap Watch next: $2.50 or $2.05?
