Explore Learning ( www.explorelearning.com ) has an intriguing set of interactive online tools (gizmos) for learning math and science. They are designed for grades 6-12, and are available on a subscription basis to teachers individually, schools, and districts. I learned about them from a Bend teacher who visited Shoreline School District in Wa, who thought they were great. I’m in conversation with the regional sales rep about getting these Gizmos available to the Pilot classrooms for 90 days as free preview (its normally 45 days) Please take a look at their web site - there are good demo movies and you can use the Gizmo’s for 5 minutes to see what they look like.
