Fairly easy to follow lesson but a couple of things to mention....
I try to incorporate mistakes into my powerpoints...if the students don't catch them...the ppt will as you'll see when you try it out.
We've doing a little bit of stuff on flashmobs...we started with the "I gotta feelin'" one a couple of weeks ago and so I put a couple more in the powerpoints just to take a break from the textbook...delete if you want!
At the end of the lesson my co-teacher have enough time to walk around the whole class (she starts at one side and I start at the other) and listen to all the diaglogues that the students made up.
