The AID (Accepting Individual Differences) curriculum guide, the fourth in a series of five manuals that attempt to foster acceptance and respect for differences as exemplified by disabilities, presents activities on the topics of mental retardation (MR) and learning disabilities (LD) for instructors, and lesson plans to be used with primary grade children. Suggestions are made for personal learning by instructors through simulation activities, reading, observation of a conference with a teacher of MR students, and use of resources. Activities relevant to MR for primary students are presented in three lesson plans on the theme, "Some students learn more slowly than others." The lesson plans, which incorporate use of the accompanying student workbook, "Amy Can Learn," are presented by theme, specific objective, activities (such as telling about hard and easy learning experiences), literature for students, a discussion guide, directions for presenting the activity, problem solving, or story time. Noted are seven activities to be used with more advanced students including reading, problem solving, and planning a project for the class to share with MR students. The section on LD also contains basic information about the handicap and suggested learning experiences for the instructor. Described are eight activities including simulating what it is like to be learning disabled. Listed in the curriculum materials and reference section are approximately nine books and three sources of free materials on the topic of mental retardation; and five books or articles, and one source of free materials on learning disabilities.
