# One Step, Crumple, Toss

The other day I did an activity that reminded me of both Kate Nowack’s Solve, Crumple, Toss game and Jon Orr’s Commit & Crumple activity, but it was slightly different.

I grouped students in twos and threes and gave each group one problem on a full sheet of paper. They struggled on a few concepts that we recently tested on, so the problem stemmed from those concepts. Each group completed the first step in their problem. That’s it. After, they crumpled the paper into a ball. After all the groups crumpled, I had them throw the ball at/to another group in the room. The receiving group would uncrumple the paper, check the work that’s already been done (correct it if necessary), and complete the next step in the problem. They then crumpled and tossed the paper to another group. This process continued until every problem was completed.

I like this activity for several reasons:

• Firstly, students must put focused effort into starting a problem. Teachers, and math teachers specifically, know that the first step of a problem can often make or break a student.
• Secondly, the bite-size chunks that they work on after each throw make long, multi-step problems easily digestible and accessible. They’re not stuck, sometimes haphazardly, on a single problem for extended periods of time. The students, without even knowing it, scaffold one another.
• From a problem solving perspective, the idea of emphasizing the completion of one step at a time could be useful. The students themselves must decipher the procedural “steps” of a problem and also relate them to a peer’s work. This may help to develop the skill of breaking down a large problem into a series of smaller ones. I’m not completely sold on my reasoning here, but I feel there’s something meaningful on this front.
• This activity affords kids the time to analyze and challenge each other’s work. It’s weird, but I’ve noticed, even with other activities, that students are highly engaged when analyzing a peer’s work. Maybe this is because teenagers are so judgemental of each other already, who knows.
• On the teacher side of things, it’s never a bad thing when an activity gives you the opportunity to walk around and assess all period. It was so helpful to provide loads of individualized feedback to them on concepts they previously struggled with.
• Lastly: who doesn’t like to throw things?! This was by far the best aspect of the lesson.

I’m still wondering about how things ended. The exit slip did show improved understanding of the concepts, which was good, but the conclusion of the activity could have been stronger. I posted the solutions for each question (they were numbered) and groups checked to see if the problem they ended with arrived at the correct answer. Most did. I also opened up a class discussion about common mistakes that were found as they checked work. That said, there still may be something better I could have done to wrap it up. Hmm.
