In this unit pupils will tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks.
Lesson Summary
You will learn to estimate and compare the duration of events and tasks.
Key Notes
- Estimating and comparing can be used when considering how long different activities might take.
- Adding and subtracting skills might be used when working out intervals or durations.
Vocabulary To Learn
- Interval: What is between two values or points. For example, the time between 9:00 and 9:15
Common Mistakes To Avoid
- Pupils need to be confident with the addition and subtraction of two digit numbers to other two digit numbers to be able to work out intervals or calculate using the intervals.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.

2. Use this key word in a maths sentence and explain it clearly. 'Interval'
What is between two values or points. For example, the time between 9:00 and 9:15. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils need to be confident with the addition and subtraction of two digit numbers to other two digit numbers to be able to work out intervals or calculate using the intervals. Correction: The idea of using tracing paper to create 15 minute, 30 minute and 45 minute time intervals is suggested and modelled. This can support the arithmetic in the lesson along with counting in 5s around the clock face.
