I'm a Phoenix!!

I have received a postive response to the questions I asked about graduate school, so I called them and started the process a couple weeks ago and I just got my letter yesterday, and it's official, I'm a Phoenix grad student.  I'm going to start my graduate classes this Tuesday.  I'm nervous, scared and excited all at once.  Speaking of all those emotions at once, storms are flaring up again today, so I need to keep my mind off the weather, nothing says spring like tornado watches in the great state of Oklahoma.  I decided to work on a matching game for subtraction and addition with and without regrouping.  I hope you like it.  I'm a beginner and when I downloaded this to google docs my border disappeared except for one corner.  Does anyone know why this happened?  I would appreciate your help.

Hope everyone has a restful night.  I'm going to get some rest before the next set of storms come in.
