S.C.O.R.E. Cyberguides is a site that was produced by Schools of California Online Resources for Education. It is based on California’s Language Arts curriculum, and offers a multitude of literature units at levels from K-12. The units include teacher and student resources. They could be used as supplemental materials, or as jumping off points for Literature Circles or independent study assignments. There is a disclaimer on the site that lack of funding has resulted in some of the units being out of date (broken links, etc…). However, it appears that even those units are still available on the site under “Retired” sections. This is helpful as a teacher could scavenge them for curriculum ideas or website suggestions.
UPDATE 7/6/14: It looks like this link no longer works. If any of you find a link to these guides that does work, please let me know, as they are a valuable resource!
