Classified Sensorial Nomenclature

Sensorial nomenclature is the vocabulary foundation. A child who knows 'convex vs concave' sees shapes differently. Indirect aim: classification, preparation for scientific language, aesthetic literacy.

• Framework: Montessori
• Unit: Sensorial
• Learning area: Visual Form
• Level: Ages 6-8

Objectives

• Name geometric and botanical details at refined level
• Match three-part cards across sensorial materials
• Connect nomenclature to real-world identification
• Build a personal sensorial dictionary

Materials

• Three-part cards: geometric solids, polygon details, leaf parts
• Control booklets
• Specimen collection
• Nomenclature binder

Instructions

1. Introduce a card set: e.g., leaf shapes (ovate, lanceolate, cordate). 2. Three-period lesson: show, ask, test. 3. Match picture to label to definition. 4. Find in real leaves. 5.
