- calculate the start time where the end time is written digitally,
- use number lines and skip counting backward around clock faces to work out start times,
- solve problems where end times and durations are given and it is necessary to calculate the start time.
Prerequisites
Students should already be familiar with
- reading analog and digital times to the nearest five minutes,
- calculating the duration of an event.
Exclusions
