Example Question #1 : Tell And Write Time To The Nearest Five Minutes: Ccss.Math.Content.2.Md.C.7

What time does the clock show? 

12 05

Possible Answers:

\(\displaystyle 12:05\)

\(\displaystyle 1:10\)

\(\displaystyle 1:01\)

\(\displaystyle 1:00\)

\(\displaystyle 12:01\)

Correct answer:

\(\displaystyle 12:05\)

Explanation:

When the hour hand (the shorter hand) points to a number on the clock, or is just past the number before it gets to the next number, we say that number as the hour. When the minute hand (the longer hand) points to a number on the clock we don't say that exact number. 

Look at the clock below. For the minute hand, we count by \(\displaystyle 5\)s. 

12 05 2

This clock is showing \(\displaystyle 12\) for the hour, and the minute hand is pointing at the \(\displaystyle 1\), which means \(\displaystyle 5\) minutes. 

Our time is \(\displaystyle 12:05\)

Example Question #1 : Tell And Write Time To The Nearest Five Minutes: Ccss.Math.Content.2.Md.C.7

What time does the clock show? 


1 55

Possible Answers:

\(\displaystyle 2:55\)

\(\displaystyle 2:50\)

\(\displaystyle 2:11\)

\(\displaystyle 1:11\)

\(\displaystyle 1:55\)

Correct answer:

\(\displaystyle 1:55\)

Explanation:

When the hour hand (the shorter hand) points to a number on the clock, or is just past the number before it gets to the next number, we say that number as the hour. When the minute hand (the longer hand) points to a number on the clock we don't say that exact number. 

Look at the clock below. For the minute hand, we count by \(\displaystyle 5\)s. 

1 55 2

This clock is showing \(\displaystyle 1\) for the hour (it is past the \(\displaystyle 1\), but not at the \(\displaystyle 2\) yet), and the minute hand is pointing at the \(\displaystyle 11\), which means \(\displaystyle 55\) minutes. 

Our time is \(\displaystyle 1:55\)

Example Question #3 : Tell And Write Time To The Nearest Five Minutes: Ccss.Math.Content.2.Md.C.7

What time does the clock show? 


2 10

Possible Answers:

\(\displaystyle 1:00\)

\(\displaystyle 2:10\)

\(\displaystyle 1:20\)

\(\displaystyle 2:02\)

\(\displaystyle 2:20\)

Correct answer:

\(\displaystyle 2:10\)

Explanation:

When the hour hand (the shorter hand) points to a number on the clock, or is just past the number before it gets to the next number, we say that number as the hour. When the minute hand (the longer hand) points to a number on the clock we don't say that exact number. 

Look at the clock below. For the minute hand, we count by \(\displaystyle 5\)s. 

2 10 2

This clock is showing \(\displaystyle 2\) for the hour, and the minute hand is pointing at the \(\displaystyle 2\), which means \(\displaystyle 10\) minutes. 

Our time is \(\displaystyle 2:10\)
