Net Folder

A flat net of faces folds up into a 3D solid — how many faces does it have?

Folding a net into a solid connects a flat drawing with a three-dimensional object.

What students practice

The game builds understanding of Geometry. Press "Fold" to fold the flat net into a 3D shape (it rotates so you can see every side). Count how many faces the solid has, enter the number with − / + or by dragging up, then press Check

shapes, area, perimeter, angles, and three-dimensional structures.

How to use it at home or in class

Students connect spatial action with precise geometric language.

They learn to see, build, and explain the shape.

Use it for individual practice, paired work, or a short class demonstration before worksheets.

Start with the game above, then continue with written practice to reinforce the skill.
