crazy foldable with the Ladder Method for using Primes to find the LCM and GCF. My Middles LOVED it! They LOVED the ladder method. They LOVED the fact that they didn't have to do 2 different steps to find the Greatest Common Factor and then the Least Common Multiple. I hope they remember it when we get to fractions!
