RandoziShape Wheel
Spin a random shape — flat 2D shapes or solid 3D ones — for geometry practice, drawing games or a quick quiz.
Tip: Ctrl + Enter (⌘ + Enter on Mac) runs it, from the list or from the page.
How it works
- Keep all shapes or pick the 2D or 3D preset.
- Spin, then ask: how many sides, corners or faces? Or find one in the room.
- Turn on “Remove winner” to go through every shape once.
What people use it for
Math class
Count sides, vertices or faces of the shape the wheel lands on.
Shape hunt
Spin, then everyone looks for an object of that shape in the room.
Drawing warm-up
Spin three shapes and turn them into one drawing.
Questions
- What is the difference between 2D and 3D shapes?
- 2D shapes are flat, with only length and width. 3D shapes are solids, with depth too: they have faces, edges and vertices.
- Can I add more shapes?
- Yes. Type extra shapes, one per line; your list is kept on this device.
