Check understanding
- A film starts at 2:15 and lasts 47 minutes — when does it end?
- Calculate how many minutes between 9:20 and 10:05
- Use a number line to show the elapsed time between two events
“If your child starts football practice at 3:20 p.m. and it lasts 75 minutes, can they work out what time it finishes — using a number line to help?”
