This document is designed primarily to help teachers in elementary and middle schools to teach basic skills in mathematics, the visual arts, and social interaction. The Introduction contains sections titled: (1) How and Where to Begin; (2) Orientation Exercises; (3) Discovering the Environment; (4) Toothpicks and Gumdrops; (5) A Process for the Product; and (6) Tips from the Architects. The next major section, Models, makes up the bulk of the material. Four individual activities that have been carried out successfully with varying ages and numbers of pupils are detailed. Each model discussion concludes with a review of related projects that have also been completed. The document concludes with a glossary of terms and a listing of suggested sources and resources. The glossary examines in separate sections terms relating to the environment, to horticulture, and to land planning and design. The resource list contains sections on books, periodicals, sources, and contacts. (MP)
