Tap every face, edge and vertex on real spinning solids — hidden parts too — then prove Euler: F + V − E = 2.
Surveying each solid means counting its flat faces, tracing the edges where those faces meet, and tallying the pointed vertices — across shapes that range from cubes and prisms to pyramids. Children develop a hands-on understanding of three-dimensional geometry: the properties of faces, edges, and vertices and how they differ between solid types. Designed for Grades 3–6, or any child moving from flat shapes to the third dimension.
A free, no-signup, no-ads math game for Grades 3–6 — practising shapes-3d, faces, edges, vertices. Play in your browser on the KidsDoMath games hub or explore more Geometry & Shapes games.
