Instructional aids for classroom use and worksheets which may be reproduced for individual seatwork are included in these support materials for unit seven of the science/math strand developed for Spanish-speaking students in grade three. They are designed to be used with the teacher's guide to the unit, which contains a timetable for their use. The instructional aids and ditto masters are to help the teacher carry out instructional and assessment activities. The worksheets are to be presented under supervision rather than as independent tasks. Science materials pertain to activities about plants and animals, life cycles, birth and death rates, food chains, and adaptation; math materials encompass regrouping techniques for adding and subtracting two-digit numbers, measurement by ruler and yardstick, liquid measurements, telling time, line segments, points, intersections, and Roman numerals to XII. All classroom materials are in Spanish. (RS)
