This site will be very helpful in the content areas of my classroom. Most of our students have never been to places that are viewed in these videos. They need to see pictures like these in order to expose them to new vocabulary.

I've used the Windows to the Universe site during my Solar System lesson and it's very useful for both English and Spanish students

Another good site with learning games is www.internet4classrooms.com.

Sorry, you should type http://www.internet4classrooms.com/learn_eng.htm for the activities.

Feel free to keep adding to this list by posting the website in the comments.
