This cross curriculum guide links mathematics, language arts, and social studies. The guide is divided into two sections. The first section provides a series of language arts activities and the second social studies activities. Within these two curriculum areas, the activities provided are based on three Square One TV formats: (1) Mathnet, the detective serial that wraps up each episode of the program; (2) the game shows, which integrate mathematics into popular game show formats; and (3) the commercials, which parody television advertisements. Each two-page spread provides two short activities to spark interest and discussion, and a step-by-step activity with a reproducible student page. Follow-up activities are also included. Topics include time, estimation, weights, graphing, and the metric system. The curriculum goals of this program are also included. (KR)
