This curriculum unit, developed by the Oregon Elementary English Project, is intended for use with fifth and sixth graders as a guide for writing. Included are discussions of the various marks of punctuation and the rules for using them, the use of capitals, writing dialog and paragraphs, and the mechanics of letter writing. The guide can be used as a basis of class instruction, as a reference for the student to use by himself, or as a work which the teacher may refer the student to. In addition to an introductory section for teachers, student exercises are provided for each area of study. (See CS 200 482 through CS 200 498 for related documents.) (HS)
