Mini Geometric Solids

A detailed guide to understanding the Mini Geometric Solids material and how it is used within the Early Years curriculum.

How does it work?

Guidepost’s Mini Geometric Solids are perfect for home use in their scale and precision. This set of 10 solids has a clear finish and includes 3 stands for keeping the curvy solids upright.

Children gain lasting familiarity with the various three-dimensional solids by learning to recognize them by sight as well as by feel (hands only – no peeking!). The names for each solid are reinforced with 3-period lessons and distance games. All of this practice lays a strong foundation for the child’s work with solids in the elementary years, when they are key to studies of in-depth geometric vocabulary, relationships, and explorations of volume.

Work with the geometric solids promotes a child’s stereognostic sense, their ability to use their hands to recognize shapes and objects.

Prerequisite Skills - It is a good idea for the child to know their basic shape names before working with the geometric solids: circle, triangle, square, rectangle, oval, and ellipse. That said, the main prerequisite for introducing this material is the child’s ability to inhibit their movements; that is, to resist touching when they are instructed to use their eyes, or to resist looking when they are instructed to feel with their hands.

how to set up.

Setup - Carefully remove all packaging material. You will need a small basket or box to hold the seven straight-sided solids for storage at the shelf alongside other Sensorial materials and for stereognostic games. The curvy solids can be stored on their stands beside the basket/box.

You will also need an opaque / not see-through square cloth of about 12” to cover the solids in their container during games. When not in use, store the Mini Geometric Solids alongside other Sensorial materials at the shelf.

Usage Tips - The Mini Geometric Solids are suitable for use either on a work rug on the floor or at a child-height table.
