I've been teaching some make-up classes and I found this great powerpoint posted by Shannon earlier this year. I added and deleted a couple of things and animated all the slides so that the pictures come up, then the name, then the description. I also added a short dialogue at the end to get the students talking about their favorite animals. I like to tell them "No cats, no dogs!" that way they actually say something new.
Thanks to Shannon for posting this originally!
