Have 2 teams "produce lemonade" while 2 teams are writing a "Fab 5 Sentence" about what a consumer is. If students write their sentence correctly, give them a dollar (play money) to "consume" lemonade from the other groups! Then the teams can swap! We did this activity in 4 teams (2 producing, while 2 wrote about what a consumer is then they swapped). I chose 1 student at each team to be a leader.
