However, you don't need an iPad to search all of the wonderful tutorials already created.

It even has common core alignment videos from grades 1 - High School, but there aren't many videos for the early grades.
Watch, Know, Learn - Educational videos.
YouTube - Google now partners with YouTube so you can create channels and favorites for easy access through your district Google account. There's even a teacher side to YouTube that you can browse (YouTube EDU and YouTube Teachers).
