3D math game · Best for grades 3-5
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.
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.
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.
