The Apple is a great resource for teachers. The site contains articles, how-to's, helpful information, career guidance, lesson plans, and ways to connect with other teachers. The site is easy to navigate and I found a lot of great resources on it. If you register (free), you will be able to take advantage of discounts from their partners, as well as participate in the social networking parts of the site.
The site is part of Monster.com.
Two really good articles that are especially timely, are 10 Things Parents Won't Tell Teachers and 10 Things Your Students Won't Tell You.
I figured they are timely because it's early in the school year and parent conferences will be upon us soon.
