The challenge allowed pupils the chance to set up their own business and learn about the world of enterprise.
One small group made dog biscuits to sell, another girl made the most amazing crocheting of beautiful flowers to sell. Others organised raffles, baking and car washing.
The pupils were visited by Alana from Clan Cancer Support and the children presented her with a cheque for over £400.
Alana Welsh, mainland community development coordinator for Clan Cancer Support, said: “These young people demonstrated great imagination and entrepreneurial spirit in their fundraising efforts and the money raised will help Clan support local people.”
