Most people are very set for the first month of school. Review of material, setting the climate of the class and reminder of your rules. Here is a site that offers handouts, lesson ideas and more for most subjects and includes K-12. I thought it would be just a few black line masters, but upon closer review I found that even after 3 clicks deep, the site revealed pages of links to sites for additional information. If you teach more than one subject, you could get lost in this site for days!
