WEBSITES: I learned about the search engine http://www.duckduckgo.com/.  This search engine doesn't "profile" you.  It gives hits to sites you may not get to right away with google etc. which tend to direct you based on other sites you have visited.
I also like to use www.kidsblogs.nationalgeographic.com/dogeared.  I like to see what other kids have written about books they have read.  Periodically we put together a display of the books they have read, print out the remarks and put them with the books.
I use http://www.dltk-kids.com/ and http://www.preschooleducation.com/ for the preschool story time group.  I find craft ideas to add to stories.  Also try http://www.mothergooseprograms.org/.
