3D Math Lab

Interactive 3D manipulatives your child can rotate, build, unfold, and slice - geometry becomes something you can touch.

What is inside

• Solid Explorer - rotate cubes, prisms, pyramids, cylinders, cones, and spheres; count faces, edges, and vertices.
• Volume Builder - build volume layer by layer with unit cubes and circle slices, and watch V = l × w × h come alive.
• Net Unfolder - unfold a box or cylinder flat and see exactly where the surface-area formula comes from.
• Three Views - match front, side, and top views of cube buildings.
• Cross Sections - slice solids and discover the 2D shapes hiding inside.
• 3D Coordinates - a real z-up coordinate system with all 8 octants, plus solids, distances, and 2D figures on the grid.
