Now you will line up three or more events by how long they last, from the shortest to the longest. *(drawing: Each bar shows how long an activity takes. The taller the bar, the longer it takes.)* **Example.** Mia had a busy morning. She brushed her teeth for 2 minutes, walked the dog for 15 minutes, and watched a show for 30 minutes. Shortest to longest: teeth, then the walk, then the show. **Tip.** To sequence intervals, pick the shortest one first. Then look at what is left and pick the next shortest. Keep going until every event has its place in line. **Recap.** Sequencing time means lining up events from the one that took the least time to the one that took the most. ## Practice 18 questions on this page, each with its working shown. ## Needs first - [Measuring Time](https://lightmysky.com/learn/mathematics/measuring-time-mt__N55B7u7HD) ## Opens up - [Estimating and reading time](https://lightmysky.com/learn/mathematics/estimating-and-reading-time-mt_3XJkeIn6J6)
