On August 2nd and 3rd, some of the best Google Certified Teachers and Googlers will get together to share their ideas and teach you great tricks and tips for using Google in your classroom. I highly recommend attending if your district is a Google Apps for Education district. I am sure it will be a fun filled two days!

Also, don't forget to join the Do You Google group. I am always looking for folks to share their ideas and successes with Google Apps.
