I have a thing for prime factorizations.

Okay, you could say I’m obsessed.

And it kills me when students mess it up because of bad handwriting. They think they’re bad at it when they just need a little help neatening things up.

So I created this handy prime factorization graphic organizer (free to download, btw) to help out.

Here’s a couple of examples of how to use it. You can have your students use highlighters around the primes (keeping them from obscuring the numbers) or you can have them just trace the boxes.

And when your students get into multiplying fractions, they can use this list of prime factorizations to help them out (also free :D).

And if you like it, please share with your PLN on Twitter, Facebook and Pinterest!
