I'm investigation possible models for learning multiplication. Below there are 6 possible models. I'd like to know if you know of more models. I've found 12 different models for understanding/doing multiplication over at Natural Math, but have not found explanations of all of these that I can easily share.
Interestingly enough, many of these videos define multiplication at the beginning of the video with no sense that there are other possible definitions.
