LessonCast is a website where experienced teachers submit—via PowerPoint, document, pictures, or web cam—a “lesson idea or management strategy in 2 minutes 30 seconds or less.” Each submission is reviewed and vetted by other accomplished teachers, and then shared online. New teachers, or those just looking for new ideas, can then search for the perfect idea for their classroom. Note: This site is still growing, so there are a few holes.
Bottom line: Whether you have an idea to share or need a new one, this site helps teachers connect in much-needed mentoring relationships. Price: Free.
