I did some more looking around online and found some additional resources for using Animoto. Below are a few links I found.
1. Bringing Lessons to Life with Animoto - This site discusses strategies for using Animoto and gives examples of lesson plans by grade level. I think this would give teacher some ideas to start with or to use in their classes to demonstrate using Animoto.
2. Tips for Producing Better Video Slideshows with Animoto - This site give some tips for using Animoto including working with pictures, text and music.
3. Teacher Training Videos - This is a site I found that has a Camtasia video, another really cool tool to use in the classroom, giving a tutorial on using Animoto.
