10 rounds. Take your time and have a go!
What children learn: the 24-hour clock, a.m. and p.m.
A clock face shows the same time twice a day. The 24-hour clock tells them apart: 3:45 in the afternoon is 15:45. In the US, a.m. and p.m. do the same job: 3:45 p.m.
In the game, each question says whether it is morning or afternoon. Children set the clock and choose morning or afternoon, then read times from 00:00 to 23:59.
Common mistakes
Children often add 12 to morning times, write 3:45 p.m. as 13:45, or forget that 12:00 is midday and 00:00 is midnight. The game keeps every question on one clock face and asks for morning or afternoon as a separate choice, so you can see which part went wrong.
Tip for parents
Look at timetables, cooker clocks and phone screens together. For afternoon times, practise "take away 12": 17:00 take away 12 is 5, so it is 5 o'clock in the afternoon.
Tip for teachers
Link it to your class timetable: what time is lunch in 24-hour time? The game marks morning and afternoon with a sunrise and a sun as well as words, so children don't rely on colour or reading alone.
A five-minute class activity
Timetable relay: write a few times from the school day on the board in 12-hour time. Teams race to rewrite them in 24-hour time, then check each other's answers.
