This game can be used a preview to Chapter 4 on the Economy in the MyWorld Social Studies book for 4th grade. The cards can be printed on colored paper and them lamented. Make copies of the answer sheet for the students. Split them up into teams and give each team a different question to work on. Once one member of the groups gives you the answer to their question, you give them the next question and so on until all questions are answered. You can even have a prize for the group that gets done first.
