I think we are getting a handle on our problem for now. At least some students are trying to be more careful. We’ve used a combination of working together to check over our work and a stiffer consequence to curb carelessness. Actually, it’s not that much stiffer than it had been; but instead of students staying in the next break and performing the necessary task, we let it accumulate all week and then they miss all or part of the main recess depending on their success or lack of success up to that point. It has made some students stop and think. Will it last? That remains to be seen.
