21st Century Educator. I'm assisting our 4th grade teachers in finding resources for their upcoming unit on division, and I'm hoping to avoid either of these situations from arising (see the videos below).

Now, my suspicion is that students will not make such egregious mistakes, but they may make more subtle mistakes based on the same principles. The key components of any division instruction should help students by:
