Operations with Time

Directions: Use the digits 1 to 9 at most one time each, place a digit in each box to make the latest possible time.

Hint

How do we find out how many minutes it will be after a certain time? What part of the time represents the hour?
What part of the time represents the minutes?

Answer

The latest possible time would be 87 minutes after 9:56 pm which is 11:23 pm. Students might pick 76 minutes after 9:58 pm, so conversations about the significance of place value in time may be worthwhile at that point.
