I've posted up slides for use with Introduction to Economic Growth on the Class Materials page.

I am a bit of a slide minimalist, so they are not done with Beamer, but they were created using TEX. They contain all the important equations and figures from the book, but there is not a lot of verbiage. I tend to leave that off the slides to force myself to talk through things more slowly.

Both the PDFs and the original TEX are posted (along with the necessary figure files). So you can use them as-is or feel free to edit them as necessary. Happy to hear back comments on them if you do use them in an undergrad class.
