  I'm posting this from 30,000 miles above the USA. Finally, I'm in an airplane that has wifi! I'm headed to Washington, DC for an education-technology conference (NECC). I'm going to be in the TechSmith booth demonstrating our Lincoln, student-created math videos!

Yay!

by Jerry - Friday, 19 June 2009, 11:30 AM
  In about 20 minutes school will be done!
I am sooooo sad! I really loved being a 6th grader!
The year went by so fast!
Just think... in 20 minutes and 1 second we will be 7th graders. Scary. I am really sad about it.

Mr. Marcos I am going to miss being in your class! Same with Mr. VanderVeen and Mrs. DeBeech!
