Lesson details
Key learning points
- 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.
Common misconception
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.
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.
Keywords
Interval - What is between two values or points. For example, the time between 9:00 and 9:15
