What it teaches
The same clock knowledge as reading, in the direction that proves it. A child can read "quarter past three" from a picture by recognising the shape. Building that picture from the words needs them to know what each hand is doing.
Quarters are included here, which is the point at which the minute hand stops being a picture and starts being a measurement.
How it works
A time appears in words and an empty clock face underneath. The child drags each hand into place. Nothing snaps to the right answer, so the placement is the child’s.
A wrong placement is not accepted, and the help shows one hand at a time in the right position before asking again.
What to look for
Expect this to be harder than reading, sometimes by a lot. That gap is normal and it is the reason this game exists — recognising is not the same as knowing.
The hour hand at quarter past is the usual sticking point: it should sit just past the number, not on it.
