About this worksheet
Find how long it is from one time to another, like 2:15 to 3:40, with two jumps on a number line.
What kids practice
Third graders tell time to the exact minute, like 4:37, and work out elapsed time, which is how much time passes from a start time to an end time. They count by 5s to the last number the long hand passed, then count on by 1s. For elapsed time they jump along a number line, often to the next hour first, and add the jumps.
Watch for
- Reading the hour from the number the short hand is closest to, even when it has not reached it yet.
- Counting by 5s past the long hand instead of switching to 1s.
- Treating 60 minutes like 100, so 2:50 plus 20 minutes becomes 2:70.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full time to the minute and elapsed time guide for 3rd grade.
