You can measure it by filling small cups. Pour cup after cup and count them. The number of cups tells you the capacity. *(drawing: Each block stands for one cup poured in. Count them: 1, 2, 3, 4.)* **Example.** Omar fills a bottle using a small cup. He pours 5 cups in. He writes '5 cups'. Now everyone knows how much it holds. **Tip.** For bigger amounts, we use litres. Always write a number with its unit, like '3 litres'. A number alone does not tell the whole story. **Recap.** Count the cups, then write the number with a unit. ## Practice 17 questions on this page, each with its working shown. ## Needs first - [Comparing Capacity](https://lightmysky.com/learn/mathematics/comparing-capacity-mt_zkFbMLpu3U) ## Opens up - [Choosing measurement units](https://lightmysky.com/learn/mathematics/choosing-measurement-units-mt_DOe893F6gN)
