This is a good blog site for educators because most tech departments do not block it. It can be used to support class blogs with students and blogs with other educators.
An educational search engine that lets you find resources based on reading level, grade level, or lexile. Subscription service that school districts buy.
Comment from Paul Hami's website:
This is a wiki built on the Mediawiki platform, and it bills itself as
"The Software Encyclopedia". The focus is on free and open source
programs. Listings are helpfully organized with concise but useful
descriptions. The listings under Education are
not extensive yet, but I expect this section will grow considerably
over time.
