Teacher Notes: I will upload a scan of teacher notes on Monday morning. Some things to be aware of:
 * You will need 20 - 60 pennies for each group and three dixie cups per group.
 * There are "infinite cloners" on some of the pages. An infinite cloner allows you to copy an object instantly. For example, the students need to add some pennies on one side of an equation. Just click on the penny and drag it...a new penny will be created.
 * Try not to drag the lesson out. Go quickly through the investigation to get to the examples. THE EXAMPLES AT THE END ARE VERY IMPORTANT! Make a connection between the concrete balance-scale method to the abstract algebraic manipulation. (Go from the pictures to the equations).
