I realize that getting young kids (in my case, third graders) to take the time to do this is often an exercise in futility, but I have students making so many "silly" mistakes this year and I'm ready to pull my hair out. I know if I read their errors back to them they would get the problems right. I've actually done this with a few students and I'm usually met with an, "Ohhhhhhhhh!"...meaning that NOW they see their mistake and they know what they did wrong. Usually they can correct their errors when I do this (or they at least get in the right ballpark), but for some reason my students this year are making countless silly mistakes on their tests, quizzes, and homework. What have you done to help combat this?
