Clock Pencil
Both hands begin at the centre. The minute hand is longer; the shorter hour hand moves between numbers as minutes pass.
Before you try
Before you play, make a prediction: Which hand is longer on this model? Explain what you expect and what part of the model will help you check it.

What happened?
Move a control to see what changes and why.
The game practises one idea at a time with simple drawn pictures. Check the same idea with real objects and your NCERT textbook (Chapter 12: Ticking Clocks and Turning Calendar, pages 175–183).

Try these ideas
- Draw the short hour hand and the long minute hand to the target time.
- Try a new puzzle with ↻. Describe what changed and which mathematical rule stayed the same.
- Complete a round, then explain your method before you move to the next one.
Why it works
Both hands begin at the centre. The minute hand is longer; the shorter hour hand moves between numbers as minutes pass.
At 6:30 the short hand is halfway from 6 to 7, not exactly on 6. Draw the short hour hand and the long minute hand to the target time.
An accurate hour hand includes the fraction of the hour already passed.
This activity connects to Ticking Clocks and Turning Calendar, NCERT Class 4 maths, printed pages 175–183. Use the picture or objects to explain each step before relying on a calculation. The game practises one part of the chapter at a time; the other three activities extend the chapter’s ideas.
Worked example: Draw the hands for 2:45. Draw the long minute hand to 9 because 9 × 5 = 45. Draw the short hour hand three quarters of the way from 2 to 3. Both hands begin at the centre.

Question 1 of 2
Which hand is longer on this model?
How many minutes are in one hour and a quarter?
Explain it in your own words
What changed? Why did it happen? Where might you notice this in everyday life?
For parents & teachers
- Try with everyday materials. Draw the short hour hand and the long minute hand to the target time. Ask the child to make a new example using paper, counters, household objects or a labelled sketch.
- Listen to the explanation. An accurate hour hand includes the fraction of the hour already passed. Ask “How could we check?” and encourage a second representation of the same idea.
