This material contains all the pieces that are used to study simple sentences in the Montessori Elementary environment.
The children use the material to break down sentences into their composite parts and analyse them. The material consists of symbols and arrows that help the children identify the different parts of the sentence. A large red circle represents the predicate; large, medium and small black circles represent the subject, direct and indirect objects respectively; dark blue triangles represent attributives and orange circles represent adverbial extensions.
The arrows in Box 2 have a question on one side and the name of that part of the sentence on the other. In Box 3, the arrows have only the terms and no questions.
The material is a key that helps children in a concrete way to explore simple sentences.
