Here are some sites that I enjoy and find useful in the classroom.
The official site for Guinness World Records and has some very interesting reading, or could be used for a kind of online Treasure Hunt.
There is also a National Geographic for Kids which can be accessed through this site.
SchoolWorld Internet Education
A valuable source of internet project options for kids of all ages.

Kids can write their own book reviews and have them posted here.
