Grammar Boxes and Grammar Box Cards

Grammar boxes are a set of eight compartment boxes. The first holds two kinds of word cards, articles and nouns; each box after adds one more part of speech, up to nine. The child reads a sentence card, builds it from colored word cards, then acts it out. Albums start it near the end of primary, at about 5.5 to 6.

What the work teaches

Direct aim. To see how each part of speech works in a sentence by building, changing and acting out sentences.

Indirect aims, the ones you will not see at once

  • Reading full sentences for meaning
  • Seeing that word order carries meaning
  • A growing vocabulary sorted into kinds
  • Preparation for sentence analysis and writing in the elementary years

Set it out before you invite the child

Eight wooden boxes. The first has two compartments, the second three, and so on, to nine in the last. Each compartment has a title card in the color of its part of speech. A larger slot at the back holds the sentence cards.

Word cards in the same colors, one word each, and sentence cards to build. Bought card sets match each box; Alison's set runs to 147 pages.

Colors differ between sets. Montessori's 1917 boxes used black for the noun, tan for the article, brown for the adjective, red for the verb, violet for the preposition, pink for the adverb, green for the pronoun, yellow for the conjunction and blue for the interjection. Many modern sets match the grammar symbols instead.

The objects the sentences name, gathered on a tray: a cup, a red pencil, a ribbon, a book.

A table with room for a sentence laid in a line, and a strip of paper and pencil for copying.

Presentation, step by step

  1. 1Bring the first box. Show the two compartments and read their title cards: article and noun.Say "This box has two kinds of words." Point to each title card as you read it.
  2. 2Take out the cards, mixed, and lay the nouns in a column. Read the first: "cup".Silent A neat column; the order of the cards doesn't matter yet.
  3. 3Find an article to go in front of it, "a" or "the", and read the pair. Let the child pair the rest.Say "The cup." Read the pair as one phrase.
  4. 4Return the cards: all the articles to their compartment, then all the nouns.Silent Articles first, then nouns, each to its own place.
  5. 5On another day, with a later box, take a sentence card from the back slot and read it silently: "Close the door."Silent The sentence card gets read in the head, not aloud.
  6. 6Build the sentence in a line from the colored word cards, taking each from its compartment.Silent Each card comes from the compartment its color names.
  7. 7Carry it out. Then swap one card, "Lock" for "Close", read the new sentence and carry that out too.Say "What changed?" Ask after the second action, not before.
  8. 8Have the child build and act the rest. Then they copy one sentence and mark each word with its grammar symbol.Say "Your turn." Then step back.

Details that hold the child's attention

One card swapped, and a whole new action.

A sentence with the verb taken out: nothing happens.

Each compartment filling up with words of one color.

Acting out "Fold the paper", then "Unfold the paper".

How the child sees a mistake

The compartments and the colors. A card returned to the wrong place shows by its color against the title card. In the sentence exercises there are exactly enough cards for the sentences, so a leftover card means a mistake.

Montessori’s name for this check is the control of error.

The three-period lesson, scripted

You need the title cards of a new box.

The three periods
PeriodWhat you do and say
1. NamingRead each title card as you set it in its compartment: "Article. Noun. Adjective."
2. Recognition"Put this card in the adjective compartment."
3. RecallPoint to a compartment and ask "What goes here?"

Our suggestion. The building and acting carry the lesson; the names follow.

Where the three periods come from, with Montessori’s own example: the three-period lesson in the glossary.

Extensions and variations

  • Changing one word and acting out the difference: "the red ribbon", "the blue ribbon"
  • Taking a card out to see what the sentence loses, as Montessori's teachers did in play
  • Writing the built sentence and marking each word with its grammar symbol
  • Sorting the cards of a finished box back by color, against the clock
  • Writing new sentence cards for a box, for a younger child to build

Variations

  • Using the color tablets with the adjective box: "the green color", "the blue color"
  • Card-only sets on a tray of envelopes, in place of wooden boxes

Prices noted . Approximate US street prices for home-use versions; they vary by maker and change often, so recheck before buying.

Making it at home

Use envelopes, small boxes or an egg carton with colored title cards, and write the word cards in matching colors. Make one box's cards at a time.

What to check when buying a set

Wooden boxes and card sets are sold separately. If you buy only one, buy the cards; the boxes can be any compartment tray.

Printables for this age

This work needs only the material, so it has no printable of its own. The shelf plan below places it among the other works for the same age.

Signs the child is ready, and signs it is done

Ready for the first presentation

  • Uses the grammar symbols for nouns, verbs, articles and adjectives in short phrases.
  • Reads a short sentence silently and acts on it.
  • Sorts objects or cards into groups without help.
  • Asks what the other symbols are for.

Ready for the next lesson

  • Builds and acts out every sentence in a box without help.
  • Says what changed when one card is swapped.
  • Returns every card to its compartment by color and by meaning.
  • Marks the parts of speech in a written sentence with symbols, the step into elementary grammar.

Fitting it into a home, not a classroom

Homeschool adaptations
If you haveDo this
A tight budgetUse small boxes or envelopes with colored title cards, and write the word cards yourself. The boxes only hold the cards; the sentences are the lesson.
A child between primary and elementaryStart the first boxes at the end of the primary years and carry on into 6 to 9. Nothing is lost by taking a year over them.
Two children of different agesThe older one acts as reader of the sentence card; the younger builds it. Swap at the next box.
No room to act sentences outChoose sentences with small actions: tie a knot, fold the paper, whisper a word.

When it does not go to plan

Common problems and what to do
WhenTry this
The sentence gets built but never acted out.Act it out yourself the first few times. The action is how the child feels what the new word does.
Cards go back into the wrong compartments.Check the colors of your cards and title cards match. A mixed color scheme makes the box impossible.
Too many new words at once.Stay with one box for weeks if needed. Each box adds only one part of speech.
Making the cards is overwhelming.Make one box's cards at a time, a week ahead. Bought printed sets save the most time here.

Hazards to check before each session

Keep small objects for the sentences off the floor if a toddler is around.

Grammar boxes: questions parents ask

What are Montessori grammar boxes?

A set of compartment boxes for word cards. Box 1 has article and noun; each box after adds one part of speech, up to all nine. The child reads a sentence card, builds it from colored word cards, and acts it out to feel what each word does.

What are grammar box cards?

The word cards and sentence cards for each box, colored by part of speech. They're sold separately from the wooden boxes. You can also write them yourself, box by box.

What age are grammar boxes for?

Most albums place the first boxes at the end of the primary years, around 5.5 to 6, and the rest in the 6 to 9 class. On this site they run from 5.5 to 9. Montessori's 1917 book treats them as elementary material.

Are grammar boxes in Montessori's own books?

Yes. The Montessori Elementary Material (1917) describes eight boxes, the first with two compartments and the last with nine, and word cards colored by part of speech. Its acknowledgments credit the photographs of the boxes to the American supplier of the day.

  1. Maria Montessori, The Montessori Elementary Material (1917)

    Part I, Grammar

    The word cards are oblongs of one size in different colors, black for the noun, tan for the article, brown for the adjective, red for the verb, and they go in eight boxes, the first with two compartments and the eighth with nine.

    In the first box the child places the black noun cards in the compartment with the black title card and the tan article cards with the tan title card, which recalls the alphabet boxes.

    The child's task is to put the right article in front of the right noun, then to gather all the articles and all the nouns back into their boxes.

    In analysis the child draws a slip with a printed sentence and builds it with colored cards taken from the different compartments.

    The teacher changes the position of a card as though in fun, and removing a word shows that the meaning of the sentence depends on the order of the words.

    In the verb box the sentences Close the door and Lock the door differ by one card, showing that a sentence changes when the action changes; the child performs the action and builds the sentence.

    For adjectives the child finds the color tablets named in phrases such as the green color, and changes only the adjective card as he changes the tablet.

    The complete grammar box has nine compartments: article tan, noun black, adjective brown, verb red, preposition violet, adverb pink, pronoun green, conjunction yellow and interjection blue.
