Reading clocks to the hour and half hour

Math - Grade 2-3

Instructions: Read each problem carefully. Show your work in the space provided.
  1. 1

    A clock shows the minute hand on 12 and the hour hand on 4. What time is it?

    When the minute hand points to 12, the time is an exact hour.

    The time is 4:00 because the minute hand on 12 means it is exactly on the hour, and the hour hand points to 4.
  2. 2

    A clock shows the minute hand on 6 and the hour hand between 7 and 8. What time is it?

    When the minute hand points to 6, it means :30.

    The time is 7:30 because the minute hand on 6 means half past the hour, and the hour hand is between 7 and 8.
  3. 3

    Write the digital time for a clock that shows the hour hand on 9 and the minute hand on 12.

    The digital time is 9:00 because the minute hand on 12 shows a full hour.
  4. 4

    Write the digital time for a clock that shows the hour hand between 2 and 3 and the minute hand on 6.

    Look at the smaller number the hour hand has passed.

    The digital time is 2:30 because the minute hand on 6 means 30 minutes past 2.
  5. 5

    It is 6:00. Where should the minute hand point on an analog clock?

    The minute hand should point to 12 because times that end in :00 are exactly on the hour.
  6. 6

    It is 11:30. Where should the minute hand point on an analog clock?

    Half hour means 30 minutes after the hour.

    The minute hand should point to 6 because times that end in :30 are half past the hour.
  7. 7

    Mia starts reading at 3:00 and stops at 3:30. How long does she read?

    Mia reads for 30 minutes because the time goes from the hour to the half hour.
  8. 8

    A movie begins at 1:30. Write this time in words.

    A time ending in :30 can be read as half past the hour.

    The time in words is one-thirty, or half past one.
  9. 9

    Sam eats lunch at half past 12. Write the digital time.

    The digital time is 12:30 because half past 12 means 30 minutes after 12.
  10. 10

    Circle the earlier time: 5:30 or 6:00. Explain your choice.

    Think about which time happens first.

    The earlier time is 5:30 because it comes before 6:00 on a clock.
  11. 11

    A clock shows 8:00. Where do the hour hand and minute hand point?

    The hour hand points to 8, and the minute hand points to 12 because 8:00 is exactly on the hour.
  12. 12

    A clock shows 10:30. Where do the hour hand and minute hand point?

    At :30, the hour hand has moved halfway to the next number.

    The minute hand points to 6, and the hour hand is between 10 and 11 because 10:30 is half past 10.
