Polyhedra turns 3D shapes into paper models you print at home on A4 or Letter paper, at the size you choose, and fold into the real thing. A 3D animation shows every fold, and every step can be read aloud for children still learning to read. Seven short lessons explain the geometry: faces, edges and corners, nets, and why there are only five perfect solids.
136 shapes, from the cube to stars, paper animals and all 92 Johnson solids. Free to start, with one-time packs. No ads. No sign-up. No data collected.
For iPhone and iPad, ages 6 and up. Coming soon to the App Store.
