Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

[divider] [/divider] Students are able to… 

  • Use a clock to tell time to the nearest minute.
  • Record time to the nearest minute.
  • Use a number line to determine elapsed time.
  • Solve problems using elapsed time.

[divider] [/divider] Students are able to…because teachers:

  • Provide opportunities for students to use clocks to tell and record time to the nearest minute.
  • Pose tasks where students can use open number lines to solve elapsed time problems.
  • Allow students to discuss strategies for determining time and elapsed time with teacher and classmates.

[divider] [/divider] Questions to ask students:

  • Have students demonstrate various times on an analog clock.
    • For example: hour, half-hour, quarter-hour, five minutes, and nearest minute.
  • Can you draw a number line to show how much time will pass ? For example, It is 11:15 AM. Lunch is at 11:50 AM.  How many minutes until lunch?
    • Sample answer that indicates understanding:

  • It is 8:30 AM. What time will it be in 3 hours?
