Telling time to nearest minute Measures and Data Telling time to nearest minute am and pm Objectives Day 1 Revise telling the time, am and pm, to the nearest minute on both analogue and digital clocks; convert between analogue and digital clocks. Day 2 Work out time intervals crossing the hour, on both analogue and digital clocks. Day 3 Calculate time intervals, crossing the hour, using both analogue and digital clocks. Before teaching, be aware that: On each day children will need whiteboards and pens. On Day 1 use the Tell The Time ITP or a large demonstration geared clock for modelling times. On Day 2 children need small geared clocks and you will need a flipchart to mock up the day’s timetable. For follow on group activities set up the Time game at https://mathsframe.co.uk/en/resources/playgame/118. Consider editing the school timetable times (slides 8 and 10) to match your own. On Day 3 you need an enlarged copy of children’s TV programme guide for group activity. Year 4

Telling time to nearest minute Measures and Data Telling time to nearest minute am and pm Starters Day 1 Pairs that make 60 (pre-requisite skills) Day 2 Roman numeral clock (pre-requisite skills) Day 3 Order months (simmering skills) or Units of time (simmering skills) Choose starters that suit your class by dragging and dropping the relevant slide or slides below to the start of the teaching for each day. Year 4

Telling time to nearest minute Measures and Data Telling time to nearest minute am and pm Starter Pairs that make 60 Pre-requisite skills – to use this starter, drag this slide to the start of Day 1 Write a selection of numbers on the board up to 50. Tell children that they need to work out the number pair that is needed to make 60, e.g. 47 + ? = 60. Time children to see how many matching pairs and number sentences they can write on their whiteboards in 2 minutes! Check by pointing at each number and choosing children to say the matching number sentence. Year 4

Telling time to nearest minute Measures and Data Telling time to nearest minute am and pm Starter Roman numeral clock Pre-requisite skills – to use this starter, drag this slide to the start of Day 2 Show children a Roman numeral clock, e.g. http://www.teacherled.com/resources/clockspin/bigbenload.html Call out o’clock times, e.g. 5 o’clock, while children write the matching Roman numeral, e.g. V., on their whiteboards. Hide the clock. Write I–XII in Roman numerals on 12 cards and give one to each child. Ask them to get themselves in order I–XII. Repeat with 12 other children. Year 4

Telling time to nearest minute Measures and Data Telling time to nearest minute am and pm Starter Order months Simmering skills – to use this starter, drag this slide to the start of Day 3 How many months are in a year? Challenge children in pairs to write the months in order (making sure they have got 12). Give each group 5 minutes to practise saying the months in order, then ‘perform’ in front of the class. Which group can say the months in order without the months in front of them? Year 4

Telling time to nearest minute Measures and Data Telling time to nearest minute am and pm Starter Units of time Simmering skills – to use this starter, drag this slide to the start of Day 3 Create a time quiz for children. They are awarded one point for every question they get right. Read out questions twice and keep the pace quick. E.g. How many seconds in a minute? How many months in a year? Hours in a day? Days in a year? Minutes in an hour? Extend to: Minutes in 2 and a half hours? Days in September? Months in 3 years? Read out answers and total up scores. Year 4

Let’s use this clock to count around in five minute intervals… Day 1: Revise telling the time, am and pm, to the nearest minute on both analogue and digital clocks; convert between analogue and digital clocks. Let’s use this clock to count around in five minute intervals… 5 past 2 10 past 2 quarter past 2… How do the hands change? Use your geared teaching clock to model moving the hands. Year 4

Each small mark represents 1 minute. Day 1: Revise telling the time, am and pm, to the nearest minute on both analogue and digital clocks; convert between analogue and digital clocks. Each small mark represents 1 minute. If the minute hand points to 2 what time is it? It’s ten past 2 or 2:10 in digital. What time is the clock showing now? Or 2:13 in digital! So it is 13 minutes past 2. Year 4

Look carefully at the minutes. How many minutes to the next hour? Day 1: Revise telling the time, am and pm, to the nearest minute on both analogue and digital clocks; convert between analogue and digital clocks. Look carefully at the minutes. How many minutes to the next hour? It’s 21 minutes to 11. What is that in digital time? Count around from 12. Children can now go on to do differentiated GROUP ACTIVITIES. You can find Hamilton’s group activities in this unit’s TEACHING AND GROUP ACTIVITIES download. WT: Small group practice of analogue and digital times on clock faces. ARE: Holiday Camp times (see Resources) – choose analogue and digital times for activities. GD: As ARE then calculate time intervals. How can you tell if it’s morning or evening?
