I can solve problems involving writing, telling and converting the time.
Lesson details
Key learning points
- Times tables help us to convert between units of time.
- There are 60 minutes in an hour.
- There are 60 seconds in a minute.
Keywords
Interval - An interval is what is between two values or points, such as 9:00 and 9:30
Convert - When we change a value from one form to another.
Common misconception
Remembering that there are 60 minutes in an hour and the values for quarter, half and three quarters of an hour. Calculations are often to and from 60 when working within an hour rather than 100
Make sure children have a clock face available so that they can visualise the times and see the minute hour hands. Children may find it useful to move the minute hand to count on and back in 5s to support their calculations.
Encourage children to visualise the times and the movement of the hands as they work out time intervals, start and finish times. Make sure children know which element of the problem is missing so that they know if an answer is a time or a time interval.
