What this lesson shows
Two jars filled with scoops: the one that takes more scoops holds more. A balance tips down on the heavier side, and cubes on the other side show how heavy.
The worked example
The lesson works this one step by step: A tall jar and a wide jar. Then your kid tries one like it on paper.
The steps
- Fill with the same scoop
- More scoops holds more
- The side that goes down is heavier
- More cubes is heavier
Helping at home
Fill two cups or bowls with the same spoon and count the spoonfuls: more spoonfuls holds more. Then hold two things, one in each hand, and check on a balance or a hanger: the side that goes down is heavier.
If your kid gets stuck
More scoops holds more. More cubes is heavier.
