I taught a review lesson on Problem/Solution writing for 6th grade. We read The Day the Crayons Quit and then did a short assignment where the students wrote a letter to themselves from an object they own but might not always use correctly. (The responses were hilarious, this is why I love these kids so much!) Between the entrance and exit ticket it looks like I did okay, the class average went up by four points! (And it would have gone up more if my host teacher hadn't left me alone with the two most talkative blocks for about 45 minutes, and if half a dozen kids in the last block hadn't handed in blank exit tickets so they could go to lunch.) Parts could have gone better, but considering I got left alone for a while and it was an early release day, I think it still turned out well.
