A supplement and ditto packet for use with unit 10 of the bilingual science/math strand developed for grade three contains both visuals for classroom use and worksheets for students which may be reproduced for individual seatwork. The timetable for when these materials are to be used is given in the teacher's guide for this unit. Instructional aids for kits 37-40 pertain to such science concepts as change, adaptation to environment, conservation, systems (solar system), gravity, and variation among animal species and a balanced diet. Math materials encompass multiplication and division, measurements, lines, angles, and practice with bank checks and bank books. All classroom materials are in Spanish. These supplementary materials support both instruction and assessment activities in the kits, each of which is designed for a teaching period of two to three weeks. (RS)
