The idea is that at the end of an important part of a unit, students need to show what they have learned. They get a piece of coloured paper and scissors. First they make a pair of pants, and then fill them with all the points they can remember. I like to hang them on pegs above the door so that they end up reading them again as they leave. Also, it looks cute.
I have done the same thing as "Dirty Laundry" teaching about the Russian Revolution or the Rise of Hitler. Explaining on an item of clothing all the things the government didn't want the people to know... then airing it as dirty laundry in public.
Students get into it because they can't help but be silly... and the little tiny pegs also get them somewhat excited.
I like it because as they start to fill the page, they end up discussing or quering or even... heaven forfend... checking back in their notes to make sure their pants are accurate. I also get a really clear idea of who understands the topic, and who is still a little mystified.
