### BIG IDEAS

- So that I can determine how much time I have left to complete a task
- So that I can find the amount of time I have to wait until an event begins or ends
- So that I know how much time I have spent on…
- So that I can figure out how much I can get done within a given time (i.e how many rides do I have enough time to get on at the amusement park)
- So that I can plan my day

### UNDERSTANDING THE STANDARD

- Elapsed time is the amount of time that has passed between two given times.
- Elapsed time can be found by counting on from the beginning time or counting back from the ending time.

### ESSENTIALS

**The student will use
problem solving, mathematical communication, mathematical reasoning,
connections, and representations to**

- Solve practical problems related to elapsed time in hours and minutes within a 24-hour period:
- when given the beginning time and the ending time, determine the time that has elapsed;
- when given the beginning time and amount of elapsed time in hours and minutes, determine the ending time; or
- when given the ending time and the elapsed time in hours and minutes, determine the beginning time.
