This curriculum guide was developed to help elementary education teachers incorporate economics lessons into the social studies curriculum. First, second, and third grade students study the concepts of: (1) economic institutions; (2) scarcity; (3) choice and decision-making; (4) specialization and exchange; and (5) economic systems. A curriculum guide is presented for each grade level, and individual study units are provided that include: (1) a generalization statement; (2) objectives; (3) strategies; (4) experience; (5) analysis; (6) other learning activities; and (7) an evaluation section. Some units contain an appendix of student related materials, and resource lists are included for each grade level. (JHP)
