Lesson 68 Learning Objectives:
Skip count by 5s and 1s to determine time intervals
Estimate time intervals on an analog clock
Add time intervals to start times to find end times
Find time intervals on a timeline
Determine elapsed times given by consecutive time intervals, with and without a timeline
Reflect:
Reflect in your math journal. Draw, create or write to share your thinking. See Lesson guide 68 for more reflection questions, real life anchoring, playful explorations and creative invitations.
When did time feel fast today? Slow?
What helped you make sense of time—skip counting, clocks, or timelines?”
What’s something you want to spend more time on?
If your family starts a movie at 6:20 and it’s 1 hour and 15 minutes long, what time does it end? What tools can you use to figure this out?
If you’re on a bus ride from 2:45 to 4:05, how can you use a timeline to find out how long it lasted?
Two students both say it took 45 minutes to finish their puzzles. One used 5-minute jumps. The other used 10s, then 5s, then 1s. How can they both make sense?
