Google Sites is an easy, coding-free site builder that integrates seamlessly with other Google Applications. For example, from within Google Sites, I was able to add the video below through a Youtube search function. (This is from a friend's wedding I attended in early October - isn't Summit amazing???)
Potential applications of Google Sites: parent/community communication, classroom blog, e-portfolio that follows them up to college. E-portfolio for me to document what is happening in my classroom as well (for future master's work), reference site for students (collection of links)
The best way to learn how to use Google Sites is just to try it out - so head to sites.google.com and give it a go.
