Created by

This presentation provides three days of teaching that cover the objectives:

• Revise am and pm.
• Begin to tell the time to the nearest minute.
• Tell time to nearest minute.
• Compare time durations.
• Revise units of time.

It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.

Day 1 Teaching
Write 7:40am, 7pm, 2:30am and 3:15pm. Remind children that am is before 12 noon (midday) and pm is after, so 7:40am is morning. Children write times in order, earliest to latest. Use ITP Tell the Time. Display both clocks and set the time increment to 1 minute. Use these clocks to calculate time intervals.

Day 2 Teaching
Use ITP Tell the Time to show analogue times, (not multiples of 5 minutes) hiding the digital clock. Children write the equivalent digital times, reveal digital clock to check. Show times to the hour and find how long until next hour, counting back in 5s from the next hour, then adding on 1, 2, 3 or 4 mins as appropriate.

Day 3 Teaching
Children in pairs list all the units of time they can. Take feedback. How many seconds in a minute? Minutes in an hour? Hours in a day? Rehearse the order of months. Show children the knuckle-method of recalling the number of days in the different months.

This teaching is part of Hamilton’s Year 3 Time and Data block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
