Lesson of the Day 62: Grammar Symbols

Published on: May 05, 2026

In the Montessori classroom, grammar is not a set of dry rules to memorize — it is a hands-on, sensorial experience. The Grammar Symbols are one of Dr. Montessori’s most elegant inventions: a set of colorful 3D shapes that children physically place above words to identify parts of speech.

What Are the Montessori Grammar Symbols?

The Grammar Symbols represent each part of speech:

  • Noun — Large black triangle.
  • Article — Small light-blue triangle.
  • Adjective — Medium dark-blue triangle.
  • Verb — Large red circle.
  • Adverb — Small orange circle.
  • Pronoun — Purple isosceles triangle.
  • Preposition — Green crescent.
  • Conjunction — Pink bar.
  • Interjection — Gold keyhole shape.

Presentation

Extending the Work

Introduce one new symbol at a time. Articles and adjectives come next. Prepositions through physical play. Adverbs modify the verb game.

The Grammar Boxes

Grammar Symbols work alongside the Grammar Boxes — color-coded boxes filled with sentence cards.

Why It Works

Self-correcting, beautiful, tactile. See also: Moveable Alphabet, Sandpaper Letters, Grammar Exercises.
