Designed for use within language arts programs as well as in the content areas, this handbook provides a continuum of activities for developing writing skills in grades five through twelve. The activities, arranged according to a diagnostic grid sheet provided for evaluation of student progress, offer practice in perception of task (point of view and following directions), organization, sentence structure, usage, vocabulary, mechanics, and using proper forms, such as business letters, letters of application and complaint, and report writing. Each exercise, which may be used individually, with small groups, or with the entire class, contains the specific skills, the objective of the activity, the procedure to be followed, and, in many cases, sample checklist directions to assist students in accumulating a series of guidelines to help them strengthen their writing abilities. A bibliography is also provided. (RL)
