Preparing to Teach Linear Algebra

I'll be teaching Linear Algebra this coming semester. It's been a decade since I last taught it. And the text is very different from the one I used before. We're using David C. Lay's, Linear Algebra and Its Applications.

I'd like to know if anyone reading this would like to mentor me when I have questions. Owen Thomas has already agreed. I'd like one or two more mentors.

I'd also like to know:

• What you've done right when you've taught Linear Algebra,
• What resources online you think are really useful,
• Where students get the most stuck,
• Anything else you think might help me make this a great course.

Thanks!
