They're competing to fundraise as much money as possible for themselves, with the chance to win extra funding from Cash for Kids!
The school that raises the most by Monday 15th June will be awarded £3,000 on top of what they raise, the second place school will receive an extra £2,000 and the third place school will receive an extra £1,000 (subject to raising an equivalent amount). Plus, every other school that raises at least £1,500 will receive a top up prize of £500.
All runners-up will also receive back every penny they raise!
