The Lexicon of the Grammar Symbols is an essential Montessori language material that provides a comprehensive reference for all grammar symbol shapes and their meanings. This German-language edition features the complete set of Montessori grammar symbols, from nouns to interjections, with clear definitions and example sentences, supporting children's progression from concrete symbol manipulation to abstract grammatical understanding.
“Education is a natural process spontaneously carried out by the human individual, and is acquired not by listening to words but by experiences upon the environment.”
Maria Montessori revolutionized grammar instruction by assigning each part of speech a unique symbol, a large red circle for the verb (the sun that gives energy to the sentence), a black triangle for the noun (a stable pyramid).
These symbols transform grammar from rote memorization into a visual, tactile exploration. The Lexicon serves as each child's personal reference, supporting the transition from manipulating physical grammar symbols on a mat to independently analyzing sentences in books. In the 6-9 classroom, this lexicon becomes a trusted companion, children consult it as a researcher would consult a dictionary, building the habit of self-directed inquiry that defines Montessori education.


Follow the Montessori method of presentation for optimal child development.
Place the lexicon on the language shelf alongside the grammar symbol box. The child should already be familiar with at least noun, verb, and adjective symbols.
Introduce the lexicon by showing the child how symbols are organized, each part of speech has its own section.
Choose a sentence from a reading exercise and invite the child to identify each word's part of speech.
When the child encounters an unfamiliar symbol, guide them to look it up in the lexicon independently.
Encourage the child to read the example sentences and notice how each part of speech functions.

They're a visual system where each part of speech has a unique shape and color, large red circle for verbs, black triangle for nouns, blue triangle for adjectives, etc. This makes abstract grammar concepts concrete and memorable.
The lexicon works best alongside the Grammar Symbol Box (physical wooden symbols) and sentence analysis strips, but it can be used independently as a reference tool.
