Net Workshop
A net is a connected flat arrangement of faces that folds into a solid without overlap. Six squares are necessary for a cube, but their arrangement matters.
Before you try
Before you play, make a prediction: What must a cube net do? 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 1: Shapes Around Us, pages 1–23).

Try these ideas
- Move a flap. Predict whether two faces will overlap, then test.
- 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
A net is a connected flat arrangement of faces that folds into a solid without overlap. Six squares are necessary for a cube, but their arrangement matters.
A cross made of a row of four squares, with a square above and below the second, folds into a cube. Move a flap. Predict whether two faces will overlap, then test.
A connected arrangement is not automatically a valid net. Predict where each face will land.
This activity connects to Shapes Around Us, NCERT Class 4 maths, printed pages 1–23. 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: Can six squares arranged in one straight strip make a cube? A cube needs six square faces. A straight strip folds around a band and repeats face positions; it cannot close the top and bottom. Six squares alone do not guarantee a cube net.

What must a cube net do?
Which solid has two matching triangular bases?

What changed? Why did it happen? Where might you notice this in everyday life?
For parents & teachers
- Try with everyday materials. Move a flap. Predict whether two faces will overlap, then test. Ask the child to make a new example using paper, counters, household objects or a labelled sketch.
- Listen to the explanation. A connected arrangement is not automatically a valid net. Predict where each face will land. Ask “How could we check?” and encourage a second representation of the same idea.
