Skill: Compare capacities
Explanation and Free Practice Resources
Capacity is the amount a container can hold, and it is compared using the same quantity of liquid or equal-sized informal units rather than the container’s height, width, or shape alone. A learner can determine and describe which of two or more containers holds more, less, or about the same amount, understanding that a taller or wider appearance does not necessarily indicate greater capacity; this reasoning supports later measurement with standard units.

Detailed Explanation: Compare capacities
Capacity tells how much a container can hold. To compare capacities, use the same-sized cup or scoop for each container. Do not decide only by looking at which container is taller or wider.
Example: Which holds more: a tall, skinny bottle or a short, wide bowl?
- Use the same small cup each time.
- Fill the bottle with the small cup. It takes cups to fill it.
- Empty the cup and fill the bowl. It takes cups to fill it.
- Compare the numbers: .
So, the bottle holds more than the bowl. The bowl may look wider, but the bottle has the greater capacity because it holds more equal-sized cups.
