#geometric solids

Lower Elementary - Geometry

This Lower Elementary student is learning geometry, identifying the number of edges, faces, and vertices for each of these 10 geometric solids: a triangular prism, a rectangular prism, a cube, a cylinder, a cone, a triangular pyramid, a square pyramid, a sphere, an ellipsoid, and an ovoid. 

While it’s entirely possible that all Mondays should start off with slime, my intention of using it to better understand 3D Solids didn’t quite go according to plan. Shorty was totally onboard for making the pink slime and enjoyed measuring out ingredients and mixing them together (definitely worth the using math for practical value). Unfortunately, she then got so hyper fixated on maneuvering said slime that she quickly lost focus on using it with the geometric shapes or discussing their similarities/ differences. Ultimately, I decided to set our timer for 15 minutes of sensory slime play before switching gears with a snack break and some more conventional workbook activities. I need to figure out how to reintroduce the 3D shapes without Shorty getting too over stimulated in the process. Maybe something with tracing, measuring angles or tessellation art?🤔

Age: 3+

Target group : blind and visually impaired children

A set of 9 geometric solids which are made of different materials, have different surfaces and make different sounds.

The set is placed in a package with spaces fitted for each solid.

There are 9 geometric solids in a set: a sphere, a regular triangular prism, a cone, a regular rectangular prism, a regular tetrahedron, a cube, a cylinder, a regular triangular pyramid, a regular rectangular pyramid.

Using the sense of touch, a child can identify a particular geometric solid, discern different materials (plexiglass, wood, metal) and textures, and fit the solid to the figure in the package. The textures of the solids and the sounds they make are to be associated with the material of which a solid is made.
