Websites for Teachers

I was browsing the internet and I came across this website http://www.eslkidstuff.com/LinksMenu.htm that has several links to other website that are extremely helpful for teachers to use. Some of these links include flashcards, worksheets, quizzes, and games that help make it easier for students to learn the English language. What website would you use and how would you use it in the classroom? The websites that I would use are the ones that have the flashcards because I feel that students learn better, when they see pictures because it is easier for them to remember the pictures than the words.
