The Google Apps Marketplace has had some good education applications since its launch last year. At that time I showed you how to add services like Aviary to your Google Apps for Education account (note, you need to have administrative rights to add apps to a Google Apps for Education domain). Today, Google announced that they have launched a separate education section to the Google Apps Marketplace. In the new EDU section you will find services designed for school use that you can add to your Google Apps for Education domain.
Learn more about the education section of the Google Apps Marketplace in the video below.
Note, not all of the services in the Marketplace are free.
