Hazel...
Thank you so much for posting this teacher tube site. On another site, I saw how to find LCM and GCF w/ stacks, but there was no explaination on how to teach it, just the model. I thought I knew how to do this by looking at the model, but I ran into some problems w/ some combination of numbers that I didn't know how to do. So, this year, I didn't feel comfortable teaching factoization by using stacks....even though I really wanted to. I used factor trees. But after seeing this video, I feel comfortable teaching Prime Factorizaton w/ stacks. Thank you so much. You made my day.
