I am all for students understanding how and why procedures work, but sometime you just need a foldable to get through to them.
Many of my students come to my class listing multiples of a particular set of numbers in order to find the least common multiple. This is all well and fine until I ask them to find the LCM of monomials with variables. Now they don't have a procedure to help them. So below is a picture story of my foldable. I forgot to put the stapler in the the first photo with the supplies, but I guess you could get away with not using it.
