Micron Foundation and Idaho Stampede has created this Challenge to show how Math is used everyday, including in the sports world. The program includes more than 1,800 students in the valley that are competing for a grand prize. The winning classroom (not school, but individual classroom) will earn a grant for their school from the Micron Foundation. The classroom will also win a trip to Salt Lake City to see a Utah Jazz game (all expenses paid).
