As a supplement to the teacher's guide for the first unit of a bilingual program in science/math for grade one, these instructional aids and ditto sheets are designed to help the teacher carry out instructional activities for kits one through four referred to in the guide. Emphasizing resources found in the classroom, the visual aids and worksheets presented here are to aid in teaching the numerals 0 to 9, ordinals (first to eighth), adding and subtracting, equivalent and nonequivalent sets, geometric shapes, and colors. Some supplementary materials are to be cut out for manipulations with small groups and individuals, while others are to be used full size. The worksheets are to be presented under supervision rather than as independent tasks. Introductions to the supplement are in both English and Spanish. (RS)
