Economics competition for 3th graders

This weeks I have assisted a professor in education economics to implement a competition for elementary school students. 9 years old students gathered in a same room from 15 schools in the district. After  taking a test in economics, they had to imagine a new idea for peeps candy. Those candies are selling for halloween, christmas and easter. The goal was to infuse to them innovative spirit. They had to play a commercial with their ideai in front of a jury of bankers. The event was sponsored by Bank of America.
