The Teacher's Desk. Over 250 lesson ideas for fifth and sixth grade teachers at this teacher-created website.
From the site:
Welcome to The Teacher's Desk, a resource designed for teachers of grades five and six. Please feel free to sit down, relax, and take your time browsing through the contents, a collection of lesson plan ideas and classroom activities. Most are my original ideas, while others have been shared with The Desk via e-mail.
