Exchange City

In second grade they have been learning about supply and demand, producers and consumers. To make it fun they decided to do Exchange City. They asked if everyone could bring in an item worth between $1 and $2. No problem. I headed up to Dollar Tree and found a cute wooden box with jewels on top. I gave it to Sammy with the instructions that she must exchange it. Well, Sammy really liked the box. Ingenious child that she is, when she got to Exchange City, she scouted out the one kid that brought the same box and traded with her! I don't know if that is quite what the teachers wanted them to do, but she followed the rules and got what she wanted!
