Free Montessori geometric solids worksheets

The ten Montessori geometric solids are all painted the same blue so that nothing but the shape tells them apart. A child picks one up, feels it with both hands and with closed eyes, learns its name, and then finds out what it does on a table. These seven worksheets follow that order: the name first, then the parts, then the behavior, then the flat shapes hiding inside each solid.

What is on each sheet

• The ten solids. A reference page with all ten drawn and named, each with a one line note, plus boxes explaining flat face, edge and vertex.
• Name the solid. Ten drawings in mixed order with a word bank: cone, cube, cuboid, cylinder, ellipsoid, ovoid, sphere, square pyramid, triangular prism, triangular pyramid. Answer key on page 2.
• Faces, edges and vertices. A table for eight solids with four columns: flat faces, curved surfaces, edges and vertices. Curved surfaces get their own column so a child is never told that a sphere has one face. Answer key on page 2.
• Roll, slide or stack. A check mark table for all ten solids, with three columns. Some solids do only one of the three, the cylinder does all three, and nothing will balance on the point of a cone. Answer key on page 2.
• Match the flat faces. Six solids and six sets of flat shapes (six squares; two circles and a curved rectangle; one circle and a fan; two triangles and three rectangles; one square and four triangles; four triangles). Answer key on page 2.
• Solids all around us. Six solids, each with a large box to draw an everyday object of that shape and a line to name it, with a bank of ideas at the bottom.
• Match the net. Four solids and four nets, lettered A to D: the cube cross, the square-based pyramid, the triangular prism and the cylinder. Answer key on page 2.

The counts on the table sheet use the wording a teacher actually says out loud. A cylinder has two flat faces, one curved surface, two edges and no vertices; a cone has one flat face, one curved surface, one edge and one vertex; the sphere, ovoid and ellipsoid have a curved surface and nothing else.
