Standard(s)

NC.2.MD.7 Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

Materials

BLM-clocks, small clock with movable hour and minute hands, pencil

Task

Read aloud each problem to the student and show each card as appropriate.

Task A: Ella’s class goes to lunch at this time (time shows 12:15 pm). What time does Ella’s class go to lunch? (twelve-fifteen) What is another way to say this same time? (quarter past 12). Show this time on your clock (student moves hands on clock to make the time).

Task C: Sam eats dinner at this time (clock shows 6:30). What time does Sam eat dinner? (six-thirty) What is another way to say this same time? (half-past six). Write this time on the digital clock. Be sure to also use a.m. or p.m. (6:30 p.m.).

Progressing

·      Incorrectly tells one or more times.

·      Verbally tells the time in at least one way correctly, but not two.

·      Reads one type of clock, but not the other.

·      Indicates a.m./p.m. incorrectly.

Meets Expectation
