Time as rotating hands
Turn the clock in five-minute steps. The minute hand moves directly while the hour hand keeps drifting between hours.
What this game shows · Analog Time as Rotation
An analog clock is two angular number lines wrapped around the same center. The minute hand spins 12 times faster than the hour hand — so reading the time is reading two rotations at once. Drag either hand and watch the digital readout follow.
- Hour hand
- short hand. One full lap = 12 hours.
- Minute hand
- long hand. One full lap = 60 minutes.
- 5-min step
- the minute hand jumps from one number to the next every 5 minutes.
Aligned with CCSS 2.MD.C.7 (tell and write time to the nearest five minutes).

The hour hand drifts as the minute hand turns.
Telling time, untangled.
01 Why does each clock number = 5 minutes? 60 / 12 = 5
There are 60 minutes around 12 hour marks, and 60 ÷ 12 = 5. So each big number on the clock is a 5-minute marker for the minute hand.
02 Why does the hour hand drift between hours? Continuous
The hour hand moves continuously, not in jumps. At 3:30, half the hour has passed, so the hour hand sits halfway between 3 and 4.
03 How fast does each hand spin? 12× ratio
The minute hand makes one full lap every 60 minutes, while the hour hand needs 12 hours. So the minute hand is 12× faster.
04 Which grade is this game for? Grades 2–3
Grades 2–3, aligned with CCSS 2.MD.C.7. Important precursor to elapsed-time reasoning in Grade 3.
