I am the last one to want to clutter up my inbox with alot of mail, but I wanted to share a resource which I have found really useful. It is a yahoo group called ClickSchooling.
What happens is you sign up for it-free and easy- and every day you get an email with an educational website recommendation-often several related sites. There are themes for each day, like monday will always be a math site, then there is a day for lang. arts, science, history, art, etc. Friday is always a virtual field trip. They are usually for multiple age groups and so far have always been useful and interesting. I've gotten so many neat ideas and activities through this group, more than I would have run across just surfing on my own. I don't use it as much as I used to now that we have dial-up (the agony!!!) so computer time is less efficient, but I have used it ALOT. For example, the Egyptian math site I wrote about came from this group.
Check it out if you get a chance.
