Measurement & Data
Telling Time to the Nearest 5 Minutes
Reading an analog clock to the nearest five minutes.
Reading the Clock More Precisely
In Grade 1, you learned to read a clock to the hour and half hour. Now that reading gets more precise — telling time to the nearest 5 minutes, using every mark around the clock's face instead of just the 12 and the 6.
Each number on a clock face stands for a group of 5 minutes when read by the minute hand: the 1 means 5 minutes, the 2 means 10 minutes, the 3 means 15 minutes, and so on, all the way around to the 12, which means 0 (or 60) minutes.
Worked Example — Reading Minutes Past the Hour
Worked Example — Reading Minutes Close to the Next Hour
Tip
Common Mistakes
Reading the minute hand's position as the number it's pointing to instead of that number times 5, such as reading the minute hand at 4 as '4 minutes' instead of 20 minutes.
Multiply the clock number the minute hand points to by 5 to get the actual number of minutes — the 4 on the clock face means 20 minutes.
Rounding up to the next hour too early, such as reading a clock with the minute hand near the 11 as the next hour already.
The hour only changes once the minute hand passes all the way around back to the 12 — until then, use the hour the hour hand has most recently passed.
Key Takeaways
- Each number on a clock face represents 5 minutes when read by the minute hand.
- Counting by 5s around the clock face converts the minute hand's position into actual minutes.
- The hour hand shows the current hour until the minute hand completes a full trip back to the 12.
Summary
Telling time to the nearest 5 minutes reads the clock face with much more precision. The final lesson in this unit turns from time to another everyday measurement — counting money.
