Lesson summary

This lesson introduces the concept of capacity, which is simply "how much a container can hold." This is a vital skill for everyday life in Ghana. We see it when our mothers buy cooking oil in different-sized bottles at the market, when we fetch water in buckets of different sizes, or even when we share a bottle of drink with our friends. By learning to compare how much things can hold, learners develop foundational skills for measurement, estimation, and problem-solving in their daily activities. Today, we will use fun, hands-on activities with water, sand, and everyday containers to become experts at this!

Lesson notes

Core Idea: What is Capacity?

Capacity is the amount of space inside a container. It's how much liquid (like water or sobolo), or how much dry material (like sand, gari, or rice) a container can hold. A big bucket has a large capacity. It can hold a lot of water. A small cup has a small capacity. It can hold only a little water.

Key Vocabulary and Definitions: Full: When a container cannot hold any more. The water or sand is right up to the top. *Example:* "Mummy filled the bucket with water until it was full." Empty: When a container has nothing inside it. *Example:* "After I drank all my juice, the cup was empty." More than: Used to compare two containers. The container with the larger capacity holds more than the other one. *Example:* "The big blue bucket holds more than the small red bowl." Less than: The container with the smaller capacity holds less than the other one. *Example:* "My 'pure water' sachet holds less than my father's big Voltic bottle." Holds the most: When comparing three or more items, this is the one with the biggest capacity. Holds the least: When comparing three or more items, this is the one with the smallest capacity.
