...but here are the sites that I visit with DD3/get work sheets from for DD3:

http://www.literacycenter.net (It has a curriculum in English, Spanish, German, and French)
http://activitypad.com/preschool-activity.html
http://www.enchantedlearning.com
http://www.learningpage.com
http://www.dltk-kids.com

--For some reason some of the web addresses don't turn into links no matter what I try...
