Display the single timetable line 14:35 as pupils settle. Take three hands-up answers, not open call-outs. Don't confirm the answer yet — let the lesson build it. Listen for whoever says 'half two in the afternoon' and hold that thought.

Walk each example aloud, one at a time. The inner 13–24 ring and the digital readout are on so the afternoon and evening times read unambiguously from the face.

• 13:00 — ask 'what did we add to 1 to get 13?' and draw out the +12 rule.
• 18:30 — point to the hands and the digital readout together; same time, two ways of writing it.
• 21:15 — let the class do the +12 mentally before you reveal.
• 00:05 — this is the make-or-break. Pupils will want to say 24:05. Stress that just after midnight the count starts again from zero.

If the board interactive is unavailable, set each time on a large printed clock face and write the digital readout (e.g. 13:00) beside it on the board, so the class still sees the hands and the 24-hour number together.

This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.

The clock is in 24-hour mode (inner ring + digital readout on). A pupil sets the hands or enters the time; the class names it both ways. Keep the +12 / −12 rule visible in pupil talk: '19 take away 12 is 7, so 19:45 is quarter to eight in the evening.' Catch the 00:30 trap — that is half past twelve at night, not half twelve in the day.

If the board interactive is unavailable, run the same four times on a large printed clock face: a pupil sets the hands and the class reads it both ways, while you write the 24-hour and 12-hour version side by side on the board.

This round is the practice bank — 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.

Watch for these landing points:

• 16:15 → quarter past four in the afternoon (16 − 12 = 4).
• 23:50 → ten to twelve at night (23 − 12 = 11, so 11:50 pm).
• 00:25 → twenty-five past midnight — the past-midnight case; 00, not 24.
• 13:05 → five past one in the afternoon (13 − 12 = 1).

If the board interactive is unavailable, call each 24-hour time aloud and have pupils set it on a printed clock face, then read it back the 12-hour way; or use the printable Convert the Times sheet rows for the same conversions.

Keep this brisk. Re-anchor the +12 / −12 rule one last time and flag the past-midnight 00:05 case as the one to remember.
