The Geometric Cabinet introduces plane geometry through hands-on exploration, building vocabulary and discrimination that supports later mathematical geometry.

• Framework: Montessori
• Unit: Sensorial
• Learning area: Visual Discrimination
• Level: Ages 3-6

Objectives

• Identify plane geometric shapes
• Develop shape vocabulary
• Prepare for geometric concepts
• Build visual discrimination of form

Materials

• Geometric Cabinet with 6 drawers
• Each drawer contains geometric shapes in frames
• Three sets of cards for matching (full, thick outline, thin outline)

Instructions

1. Remove one shape from frame using knob. 2. Trace outline with two fingers. 3. Name shape (three-period lesson). 4. Match to full card, then outline cards. 5. Find shapes in environment. 6. Progress through all drawers.
