Created to help students understand how plants were used for food, for medicine, and for arts and crafts among the Ojibwe (Chippewa) Indians, the game Tree-Ties combines earth and social sciences within a specific culture. The game requires mutual respect, understanding, and agreement to succeed. Sounding like the word "treaties", the title is a play on words. "Tree" refers to the emphasis on botany. How it "ties" to other aspects of culture is what the game is about. The game involves 36 players, divided into teams of 6, and allows students to study information individually, cooperatively with other team members, and then competitively. Plants and plant products/parts included in the game are pumpkin blossoms, wild rice, maple sugar, birch bark, basswood fiber, corn, arrowhead, dogbane, clover, onion roots, burdock leaves, tobacco, golden rod, wild geranium roots, calamus, lady slipper roots, honeysuckle, chokecherry bark, raspberry root, sasparilla root, poplar bark, tamarack bark, catnip leaves, dogwood bark and roots, aster roots, balsam poplar, prickly ash, moss and cattail down, spruce, hickory, hemlock, oak, maple, and alder. All these plants and trees are listed together with their uses. The booklet details rules for playing the game and provides examples of each of the 36 game information cards. (NEC)
