I'm working on mapping my math curriculum, and I realized that my division unit needs some revamping. We cover the basic idea of division, introduce remainders and the idea that what you do with them depends on the situation. We also work on the idea of division as the inverse of multiplication. We do not get into long division, and most of the activities I find when I search are for that. So, what great ideas are floating out there? I'm looking specifically for hands-on practice and game ideas.
