The curriculum modification guide, developed by project success (Nebraska) through a Title III grant for language disabled elementary level students, contains suggested activities and instructional materials to be used in units of art, health, mathematics, music, science, and social studies. Explained are program planning, criteria for selecting instructional materials, and goals. The curriculum modifier (a consultant to teachers) is said to perform functions such as preparing individualized prescriptions, selecting appropriate instructional materials and collecting data for ongoing evaluation of students. A chart based on the modifier's tasks specifies teacher behavior, task analysis, and student behavior. Usually specified for subject areas are teacher instructions, activities, instructional materials, grade level(s), skills to be developed, and sources for materials. Art activities such as stringing beads to make a necklace are suggested for developing visual and motor perception. Activities such as visiting a grocery store are suggested for 18 health units featuring aspects such as alcohol, dental health, and safety. Offered for 38 subcategories pertaining to number operations, measurement, geometry, and computation in mathematics are activities such as preparing a bingo game using fractions. Provided in the science section is a model unit on plant growth. Social studies activities are given for the following grade level units (number of topics per unit are in parentheses); grade 1, the family (27); grade 2, the neighborhood (14); grade 3, cities (18); grade 4, Nebraska (13) and geography (18); grade 5, U.S. (17); and grade 6, Canada and Latin America (15).
