⚖️ Comparing Measurements

What you’ll learn

1. Longer or ShorterCompare and order lengths using longer, shorter, and the bigger number.To compare lengths measured in the same unit, look at the numbers — the bigger number is longer. Three or more lengths can be lined up in order from shortest to longest.
2. Heavier or LighterCompare weights using heavier and lighter, and sort objects by weight.A balance scale drops on the heavier side. Objects can be sorted as heavier or lighter than a chosen thing, like a school bag, to compare their weights.
3. More or LessCompare amounts of liquid using more and less.Amount tells us how much a container holds. A larger container, like a jug, usually holds more than a small one, like a cup.
4. Compare CarefullyUnderstand that fair comparisons need the same unit for both things.The golden rule of comparing is to measure both things in the same unit first. Then the bigger number really is more — whether it is length, weight, or amount.
