Inexpensive and DIY Geometric Solids and ExtensionsI love the Montessori geometric solids at any time of year. Montessori geometric solids are beautiful sensorial materials and wonderful for the stereognostic sense (the process of feeling objects and recognizing them based on what is felt). This is a great time of year to place an extra focus on geometric solids with the coming of Easter and fun with ovoid-shaped Easter eggs!

Geometric solids aren’t an easy material to make and are generally purchased by both preschools and homeschools. There are some inexpensive versions available. You’ll find an interesting discussion about buying geometric solids at Homemade Homeschool.

Inexpensive Geometric Solids

Note: It’s best if the geometric solids are all one color. (The traditional geometric solids are all blue for isolation of difficulty so the child doesn’t confuse shape with color).

DIY Geometric Solids

There are tutorials for making at least some of the traditional geometric solids (cube, sphere, cone, cylinder, rectangular prism, triangular prism, ovoid, ellipsoid, triangular-based pyramid, and square-based pyramid) used in Montessori schools. Even if you’ve purchased geometric solids, following the DIY tutorials could be great extensions for children at more advanced levels.
