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 10, it means 10 minutes past the hour.
Corrected: When the minute hand points to the 10, it means 50 minutes past the hour because each number represents 5 minutes.
The corrected sentence is: "When the minute hand points to the 10, it means 50 minutes past the hour because each number represents 5 minutes." The error was clock reading error: the original sentence "When the minute hand points to the 10, it means 10 minutes past the hour." needed to be fixed.
2. Fix the sentence:
At 9:52 the hour hand is pointing directly at the 9.
Corrected: At 9:52 the hour hand is almost at the 10 because it moves slowly toward the next hour as minutes pass.
The corrected sentence is: "At 9:52 the hour hand is almost at the 10 because it moves slowly toward the next hour as minutes pass." The error was hour hand position error: the original sentence "At 9:52 the hour hand is pointing directly at the 9." needed to be fixed.
3. Fix the sentence:
Breakfast at 7:30 in the morning is 7:30 PM.
Corrected: Breakfast at 7:30 in the morning is 7:30 AM because AM means before noon.
The corrected sentence is: "Breakfast at 7:30 in the morning is 7:30 AM because AM means before noon." The error was AM/PM error: the original sentence "Breakfast at 7:30 in the morning is 7:30 PM." 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 3, it shows 15 minutes past the hour.
Each number on the clock stands for 5 minutes, so the 3 means 3 x 5 = 15 minutes past the hour.
2. A clock with the hour hand between 4 and 5 and the minute hand on 10 reads 4:50.
The minute hand on the 10 means 10 x 5 = 50 minutes, and the hour hand between 4 and 5 tells you it is still in the 4 o'clock hour, so the time is 4:50.
3. If gym class starts at 1:15 PM and lasts 30 minutes, it ends at 1:45 PM.
Starting at 1:15 and adding 30 minutes gives 1:45 because 15 + 30 = 45 minutes past 1 o'clock.
4. Evening times after noon use PM after the time.
PM stands for the hours from noon until midnight, so all evening times use PM after the number.
Part C: True or False?
Read each statement. Circle True or False.
1. When the minute hand is on 12 and the hour hand is on 3, the time is 3:00.
True False
When the minute hand points to 12, it means zero minutes past the hour, and the hour hand on 3 means it is exactly 3:00.
2. There are 100 minutes in one hour.
True False
There are 60 minutes in one hour, not 100, so this statement is false.
3. The hour hand is shorter than the minute hand on a clock.
True False
On a clock, the shorter hand always shows the hour and the longer hand shows the minutes, so the hour hand really is shorter.
