Hello! Awhile back I remember seeing a post about lessons on prime factorizations so I thought I would share something I did with my students last week. I had them pick a number over 50 to factor, then diagram using construction paper. I had them use red squares for composite numbers, green stars for prime numbers, and then had them write the prime factorization at the bottom. It ended up being a really quick (maybe 45 minutes for the whole class to complete) and interesting activity. We "discovered" as a class that it doesn't matter which factors you pick to begin with' you will always end up with the same prime factorization. Anyways, I took some pics, some of them came out pretty neat! Right now I am trying to figure out how to use prime factorization in a card game. Any ideas???
