Lesson details
Learning outcome
You can solve problems involving converting between units of time
Key learning points
- There are 60 minutes in an hour.
- There are 24 hours in a day.
- There are 12 months in a year.
- There are 365 days in most years.
Keywords
Convert - To convert is to change a value or expression from one form to another, such as minutes to hours.
Common misconception
Some pupils might think 8:45 + 20 mins = 8:65. As our system of time is not based around the decimal system, this is incorrect.
Some pupils may still not be fully au fait with telling the time, though the lesson presumes they are. Providing them with a mini-clock with movable hands will help to reinforce the idea of bridging to and then from the o'clock time.
Teacher tip
The lesson uses a number line as a way of supporting mental calculation when working out time differences. It presumes that pupils already have good fluency with number bonds to 60. The third cycle focusses on building timetables and the next lesson looks at interpreting timetables.
