Encourage tinkering with ideas, relationships, connections. Set up situations where students have to find information not readily available in school texts. Provide opportunity for students to design open-ended explorations of the concept. Provide multiple options so students can plan a unique "proof" of learning.
Magazine toy trading
Objective: To extend students' concept of bartering.
Activity: Using magazine or newspaper ads for toys, have students cut out pictures of toys they would like to have. They pretend these toys are real. Have them attempt to trade with other students. Reinforce the idea that a trade is not made unless both parties agree.
