Pipo Games is an excellent site for educational games for kids ages 3-12. The game helps build skills towards child development and learning. Also, another great feature is the ability to embed their games into a site/blog. Keep in mind that while you can demo and play some games this is a paid site similar to Education City.
Appitic is a terrific site for finding educational apps. The site reminds me a lot of Mind Leap in that a user can search by grade level or subject. Appitic has a collection of over 1300+ apps and is designed by Apple Distinguished Educators (ADE) for finding the best tools for the classroom.
Drawpr is a nice new free site for file sharing. This is done in a rather unique way by dragging and dropping files on a bucket. These buckets can be made public for others to download your files, or private so only you have access to them. The max size a file can be for upload is 50 MB.
Wondrous Worksheets is a great site for educators for finding worksheets on any number of subjects. Keep in mind to access all the worksheets there is an $11.95 charge for a 1yr subscription.
Artsonia is a great free site for art teachers that I just found out about from Free Technology 4 Teachers. This site allows students to upload their art work to an online gallery. However, there is also a teacher section which has lesson plans for grades PreK-12th.
