A cup can be full or empty. It can also be somewhere in between. You can compare two cups to see which holds more. *(drawing: Cup B holds more water than Cup A.)* **Example.** Mia pours a little milk in her cup. Leo pours a lot of milk in his cup. Leo's cup has more milk than Mia's cup. *(drawing: This bar is half shaded. A cup like this is half full.)* **Tip.** To compare fairly, use cups that are the same size. Then check which one has more water inside. **Recap.** Compare containers by seeing which one holds more or less water. ## Practice 17 questions on this page, each with its working shown. ## Needs first - [Measurable attributes of objects](https://lightmysky.com/learn/mathematics/measurable-attributes-of-objects-mt_NtJYlJdUe9) ## Opens up - [Capacity and volume](https://lightmysky.com/learn/mathematics/capacity-and-volume-mt_4lp_b5Pzik)
