Background: As a math teacher, I have been horrified at how my students avoided canceling like it was the plague. I would cringe as I watched students multiply first, then reduce. Something as simple as 2/3 x 1/2 was made twice as hard. All they had to do was cancel the 2's and get a final answer of 1/3. Sooo much easier!! This year I decided to create a series of resources, leading them to discover for themselves just how useful a skill it is. Description: In this resource, I introduce the idea

Prime Factorization or Factor Trees Worksheet - 21 problems - Students factor numbers ranging from 18 to 1001. - 2 Modified versions with scaffolding included (see thumbnail for how extra support is given) - Mini lesson included at top for students. Great for absent students or students who need extra support!
