MATH DAY 2012

Our Algebra class (and our two Montana Digital Academy students) will attend this year's Math Day at the University of Montana!

More information can be found at the following link:

It is IMPORTANT to note that we will be leaving the school EARLY:
about 7:45am

Again, that is a 7:45am departure!!!

We will return to the school in time to ride the buses home.  Volleyball students will be met at the university and delivered to Valley Christian for their game.  They will be supervised until the team bus arrives.

Lunch options include:

• Bring a sack lunch
• Bring money to purchase food at the Student Center
• Bring $5 to purchase a pass to the U of M student cafeteria!!!

Should be a great day!  I will be sure to take a camera and post pictures here.
