Time to the Minute — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
When the minute hand points to the 8, it means 8 minutes past the hour.
Corrected: When the minute hand points to the 8, it means 40 minutes past the hour because each number stands for 5 minutes.
The corrected sentence is: "When the minute hand points to the 8, it means 40 minutes past the hour because each number stands for 5 minutes." The error was clock reading error: the original sentence "When the minute hand points to the 8, it means 8 minutes past the hour." needed to be fixed.
2. Fix the sentence:
At 11:57 the hour hand is pointing right at the 11.
Corrected: At 11:57 the hour hand is almost at the 12 because it moves toward the next number as minutes pass.
The corrected sentence is: "At 11:57 the hour hand is almost at the 12 because it moves toward the next number as minutes pass." The error was hour hand position error: the original sentence "At 11:57 the hour hand is pointing right at the 11." needed to be fixed.
3. Fix the sentence:
The school day ends at 3:15 AM.
Corrected: The school day ends at 3:15 PM because PM is used for afternoon times.
The corrected sentence is: "The school day ends at 3:15 PM because PM is used for afternoon times." The error was AM/PM error: the original sentence "The school day ends at 3:15 AM." needed to be fixed.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. When the minute hand points to the 11, it shows 55 minutes past the hour.
Each number on the clock equals 5 minutes, so the 11 means 11 x 5 = 55 minutes past the hour.
2. A clock with the hour hand between 6 and 7 and the minute hand on 3 reads 6:15.
The minute hand on the 3 means 3 x 5 = 15 minutes, and the hour hand between 6 and 7 shows the 6 o'clock hour, so the time is 6:15.
3. Half of 60 minutes is 30 minutes, which is half past the hour.
Half of 60 is 30, so half past any hour means 30 minutes have gone by since the hour started.
4. If dinner starts at 6:00 PM and takes 25 minutes to cook, it is ready at 6:25.
Adding 25 minutes to 6:00 gives 6:25 because you count forward 25 minutes from the start of the hour.
Part C: True or False?
Read each statement. Circle True or False.
1. 2:00 AM is a time most people are sleeping.
True False
2:00 AM is two hours after midnight, which is the middle of the night when most people are asleep.
2. When the minute hand goes all the way around the clock, 30 minutes have passed.
True False
One full trip around the clock equals 60 minutes, not 30, so this statement is false.
3. The numbers on a clock go from 1 to 12.
True False
A standard clock face has exactly the numbers 1 through 12 arranged in a circle, so this is true.
