Ms. Gonzalez uses this lesson to introduce her students to several economic concepts, including production and cooperation. Using a children’s book as a guide, Ms. Gonzalez reviews with her students how people work cooperatively on an assembly line to make a product. The students then experience the concepts of production and distribution through an activity in which they create an assembly line in the classroom and prepare hand–made bread. http://www.learner.org/resources/series166.html
