Help Isla raise money

My name is Isla and I am in Grade 3 at TCA. The last two years I have done the half mile fun run, but this year I am training for the full 5K!

My goal is to raise $300 for my school, and to get a water fight with the principals. 

Incentive Levels: 
$60 = a dress-down day pass 
$100 = a no-homework pass 
$200 = a water sponge battle with the principals 

The two students who raise the most money will get to have lunch at school with their favorite teachers. The class that raises the most money per student will get a pizza party and an extra recess.
