Practice naming 2D shapes and counting their sides and corners — triangles, squares, rectangles, pentagons, and hexagons.
A triangle has 3 sides, a square and a rectangle have 4, a pentagon has 5, and a hexagon has 6. A polygon has the same number of corners as sides.
Cubles kits are geometry in your hands: nets, faces, edges and vertices that fold and click into a poseable 3D character. No scissors, no glue, about 15 minutes.
