The supplement and ditto packet to the science-math strand of unit six for second graders features visual materials to help the teacher carry out the instructional and assessment activities for the unit's four kits. Illustrations are provided to help stimulate oral language and conceptual development. Some are designed to be cut out for manipulation with small groups and individuals, while others are full sized and may be colored and mounted on cardboard to facilitate their use. Most of the pictures in the supplement are of plants and animals and their habitats, and are used to reinforce the concepts of reproduction, adaptation, environment, conservation, and ecology. The ditto packet provides ditto masters for visuals for group activities and individual seatwork. Written work for regrouping, fill-in-the-blank, and matching exercises is provided along with equations and word problems. Other visual materials assist in teaching measurement; the cardinal points of north, south, east and west; and map usage. Language on materials for the classroom is in Spanish. Worksheets for individual pupils are intended for presentation under supervision rather than as individual tasks. (DS)
