Last week, my AP Statistics class took their final exam: 20 multiple choice questions and 4 free response, basically a half-AP.

I wanted to review the answers with them, especially noting some common mistakes, and also give them a chance to reflect on how it went. I’m really excited with how it went down.

Students went into their (new!) groups of 4 (new seating chart today) with a copy of each question, distributed one per person. My second class had half groups of 3 and half 4, which didn’t matter here (the ghost just got the fourth question and they passed through the ghost).

They got 2 minutes to silently answer as much as they could on the question in front of them, then passed and had two more minutes, and so on. Then they had 10 minutes as a group to come up with their best answers to all four questions. There were a ton of good discussions, both in writing before they were allowed to talk (“I got that too!” “I think its center not spread because…”) and verbally.

Once that wrapped up, I reviewed solutions and they scored their group solution. It also gave me a chance to remind them how rigorous the AP exam is–for students who are used to getting perfect scores fairly easily, the difficulty of the AP exam comes as a shock, and they have a hard time wrapping their heads around 75% correct on multiple choice being GOOD.

It was one of those periods in which I kind of felt like I wasn’t doing much, but I think it was so valuable for my students. This would even work well for a word problem (each person does one step) or explaining several different kinds of problems for a review. By the time they were allowed to talk, several students were really invested in justifying their perspective.

Have you ever tried a write-around strategy like this? Any tips for how it could go even better next time?
