Do your students struggle as much as mine with prime factorization? We slogged through factor lists and trees until I discovered the ladder method, and WOW, it blew our minds! It's quick and easy, and a modified version makes finding GCF/LCM a breeze.
Answer keys are included (and work great as student handouts, too!).
Come back soon for notes and practice on the ladder method for GCF/LCM!
