We have been learning to identify naming parts (subjects) and telling parts (predicates), so that we know how to write complete sentences. Here are two activities that have helped us understand this concept.
We made sentence flip books. There are six naming parts on one side and six telling parts on the other. You can flip the pages and make silly sentences.
There are naming parts on one cube and telling parts on the other. Each child rolls the cubes and combines the naming and telling parts to make complete sentences.
