Four scales developed by Marion Monroe for recording, describing, analyzing, and rating children's oral language skills are described and presented in this paper. The skills assessed by the scales are first described as follows: (1) how a child thinks, as revealed by the quality of ideas; (2) how a child thinks, as revealed by definition of words; (3) how a child uses words, as revealed by ability to verbalize ideas; and (4) how a child uses words, as revealed by command of sentence structure. Eighteen activities are then described that will encourage children to expand their vocabularies and express themselves orally. (GW)
