My AP Macro class went outside for part of the hour this morning and worked in teams on the 2005 FRQ Form B questions. It was nice to have them see the enlarged graphs and actually be able to walk on them too. For instance they drew a money supply graph, followed by a long aggregate supply and demand, and put together a Phillips Curve to demonstrate what happened on the AD/AS graph. It was a fun and different way to work with these problems and I am going to try the same thing with Micro this afternoon. (Cost: only one box of sidewalk chalk at Target for about $4.00)
