January 21, 2013 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). Actually, these videos could be great hooks to see if students can figure out what mistakes the people in them are making... A key problem in both of these videos is that these (fictional) people are making key mistakes in their use of a standard algorithm which they clearly do not understand, nor do they seem able judge how accurate their solutions are. Now, my suspicion is that students will not make such egregious mistakes, but they may make more subtle mistakes based on the same principles.
