Geometric Solids Activity *The montessori geometric activity is much more expensive. I recommend buying your own shapes and either making your own bases or use a chart like the one listed on the left of the page. You will save over 50% by making your own activity tray.
Bring the tray to the work area. Invite the child to feel each form as you point out the features of each one. Have the child close their eyes as you place two solids under a cloth or in a bag and ask the child to feel and describe them. The names of the cube and cone are introduced in a seperate lesson including the bag game again. This time name the solids. Introduce the base or chart and have the child match the shapes with the base. This exercise is repeated in several lessons. Gradually add in the rest of the solids. The goal of this activity is to help the child recognize geometric forms through visual, muscular-tactile, and stereognostic senses. The child will also learn the vocabulary for geometric forms.
