Algebra II Files: Matrices

(See more Algebra II files and FAQs here)I’m sure this is post you’ve been waiting for!  This is totally how I feel after I typing up a matrices worksheet:

But have no fear, my little math darlings, I’m here to save the day….with handwritten notes:

Ok, but at least I typed up the homework for ya!  With graphs!

Then, yup, it’s back to handwritten again:
