The hour hand moves too
At half past four the short hand is halfway between 4 and 5, not on the 4. Dragging the minute hand here moves the hour hand with it, the way a real clock does.
Drag the hands and read the time — in numbers, in English and in Khmer. Work out what time it will be later, how long something takes, and practise reading and setting the clock.
Drag either hand. The arrow keys move the time; Page Up and Page Down move a whole hour.

Time does not work in hundreds, so 7:45 + 35 min is not 7:80. Go to the next o'clock first (15 min to 8:00), then add what is left (20 min → 8:20).
am is from midnight to midday, pm from midday to midnight. Bus and flight times use the 24-hour clock: add 12 to any pm hour, so 4:40 pm is 16:40.

Our tutors help children read the clock, count on in time and plan their day — practical maths they use every day.
