Below are a few educational websites. I will be adding more on as the year goes on.
brainpop.com movies on lots and lots science and health topics, now requires you to sign up for a free trial
funbrain.com fun and cool games, best games site on the web, in my opinion!
internet4classrooms.com Awesome!! Lists 3rd grade skills and links to games on the web to practice them.
ixl math games Great website! Links for specific skills by grade level. More benefits if you become a member, but I think you can access all the activities as a guest.
http://multiplication.com/ Excellent website for practicing multiplication skills. There are about 15 fun, interactivegames to choose from, and most games have 3 levels.
http://www.links.provo.edu/Pages/3rdGradeGL.htm This website provides practice for elementary grade levels in all subject areas.
