The children were praised for choosing products with the fair trade logo from the shelves of the Co-operative in nearby Arthur Road.
Claire Jenkins from Co-operative Childcare said: "The activity went really well, the children really enjoyed hunting for the fair trade logo in the form of a treasure hunt."
As part of Fairtrade fortnight, the children also created a banana tree by gluing and sticking yellow and green materials onto banana and leaf outlines.
The children will be making banana cakes using fair trade bananas and selling them to raise money for the Teenage Cancer Trust.
Fairtrade fortnight is a national initiative which runs until Sunday, March 8.
