I am really excited about the Prezi software. I hope that my commercial and BP8 relayed enough information that you are willing to try the application for one of your lessons and/or will share the site with your students.
Pay no attention to the age of the 'student' actors. School has yet to begin so I enlisted my coworkers and our fabulous PTSA President. Thank you Ursula (Ms. Hall), Jerolyn (timid student) and Kathy (runaway student).
