Students are so used to math class being only about answers that they don’t include statements about the problem, information about their thinking, etc. I use a lot of writing assignments to help with these issues, but still on the every day assignments; it’s hard to get them to even summarize the problem. Then when it’s time to do portfolios, their daily work is useless as a reflection of their understanding. So, I started randomly collecting homework and grading just for clarity of presentation. Students would slip if I hadn’t collected papers in a while, but they did improve.
