Look at the clock on the screen. We are going to point to each number, one after the other, starting at the 12. As we touch each number, say the count with me: 5, 10, 15, 20, all the way round to 60.
Here is the puzzle: there are only twelve numbers on the clock, but a whole hour has sixty minutes. So why does each number stand for five minutes, and not just one?
Point to each numeral on the IWB clock in turn and have the class chant the fives count round to 60. Give five seconds of quiet think-time on the puzzle question before taking two or three hands-up answers. Revoice the key idea: the twelve numbers split the sixty minutes into twelve equal jumps of five.
Look at each clock. Count round in fives to where the long hand points, and each time ask yourself: are we counting past the hour or on to the next one?
Ten past 3: long hand on the 2, count fives from the 12 (5, 10). Right side means past.
Twenty-five past 7: long hand on the 5, count 5, 10, 15, 20, 25. Still past.
Ask past or to? before naming the minutes.
Twenty to 10: long hand crossed the 6, up on the left at the 8. Switch to counting minutes still to go, from the 8 round to the 12 is 20 minutes. This switch is the make-or-break idea.
Five to 12: long hand near the top on the 11, five minutes left to the 12.
Half past 1: long hand straight down on the 6, count to 30 minutes past, half the hour.
Quarter to 8: long hand on the 9, 15 minutes still to go, a quarter of the hour. Pupils set half past and quarter to themselves next step.
Now we set five-minute times on the clock ourselves. When a time is named, one of you comes to the board and drags the long hand to the right number while the rest of us count round in fives to check.
We will try: half past 1, twenty past 4, quarter to 8, and five past 11. We met half past and quarter to on the board a moment ago — now we set them ourselves. For each one, look at where the long hand lands. If it has not yet passed the 6, we count minutes past the hour. If it has crossed the 6 and is climbing the left side, we count minutes to the next hour.
This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.
The clock loads showing 12 o'clock, so nothing gives the first answer away.
Name a time, send one pupil to drag the long hand to the matching number, and have the whole class count the fives aloud to confirm. Listen for pupils who try to count to when the hand is still on the right side. Revoice: has the long hand gone past the 6 yet? If not, we are still counting past.
We write times in words like this: twenty past 4, five to 9 — the minutes first, then 'past' or 'to', then the hour number.
Here are four clock faces — Clock 1 to Clock 4, in order down the screen. In your maths copy, write one line for each clock: the clock's name, then the time it shows, in words. Before you write each one, check which side the long hand is on: right side means a 'past' time, left side means a 'to' time.
Give the class quiet writing time. The answers, in order: ten past 2, twenty-five past 6, twenty to 11, five to 4. Walk the room glancing at whether pupils have chosen 'past' or 'to' correctly — no individual marking, this is whole-class copybook practice, not assessment.
Today we work through these times together at the board: ten past 4, twenty-five past 9, twenty to 6, then five to 1. The 'to' times catch people out, so we will say each one aloud and count the fives before we check it.
These are the practice questions — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.
For each target, ask the pupil at the board: do we count minutes past or minutes to the next hour here? The first two are 'past' times; the last two cross the 6 and become 'to' times. Use the on-screen ✓ as part of the narration when a pupil sets the hands correctly.
Watch the last target closely: at five to 1 the short hand sits almost on the 1. Some pupils will say 'five to 12' because the clock still reads twelve-something. Ask which hour comes next? — the short hand is nearly at the 1 because the next hour is 1, so we say five to 1.
When the long hand is past the 6, why do we start saying 'to' the next hour instead of 'past'?
Listen for pupils naming the 6 as the turning point — once the long hand is climbing the left side, the next hour is closer than the one just gone. Revoice a strong answer: so the side the long hand is on tells us whether to say past or to. Head off the common slip of counting 'past' all the way round to 11.
Next we will match the time on a clock face to the numbers on a digital display, so we can read both kinds of clock.
Recap the past-or-to switch one last time. Suggested timing: the IWB-led arc above fills about 42 of the 50 minutes; the rest of the slot is the activity-book page, which pupils work on while you circulate.
