Education Index is an annotated guide to education-related sites on the Web. They're sorted by subject or lifestage. This is not an all-inclusive list, sites are selected for inclusion and awards are given to the best. Within broad catagories arrangement is alphabetical. The annotations do not give grade level indications, so finding a suitable site could still be a challenge.
Arrangement is by subject only, with suggested grade levels as part of each description.
Although there are plans listed in most subject areas, the strength of this site is the emphasis on current events. There is also a tie-in to the Newspapers in Education program.
