Google Junior Training Series
Global GEG (Google Educator Group) is a team of volunteer Educator Leaders from around the world who work to provide resources and opportunities to teachers, schools, and educational communities.
Their Google Junior Training Series is a collection of dozens of short task-specific videos, created to help students learn more about Google educational products. The embedded document below is an organized list of these videos, complete with a table of contents. The first four videos below are from that list and should give you a sampling of what is available.
