The Sentence Analysis 1st and 2nd Set in English (L100) provides the arrows, circles, and labeled components used in Montessori grammar work to help Elementary children visually map the function and relationships of words within a sentence. It supports the Language curriculum from early grammar through complex sentence structures, making it essential for any Lower or Upper Elementary classroom engaging in deep language study. A complete, durable set means multiple children can work simultaneously on sentence diagramming without interruption to the flow of independent work.
