Hundreds passed through the gates of the Joseph Hood Primary School at the weekend to hook ducks, enjoy refreshments and raise money for new playground equipment.
The annual school fair in Whatley Avenue, Raynes Park, collected about £4,000 in proceeds including entry fees on Saturday, July 5.
Headteacher Anita Saville said: "It was a great day, everyone had a lovely time."
The funds will go towards new playground equipment at the school.
Antonio Campana, five, and Paula Lerin, also five on the bouncy castle.
There was a barbecue, stalls, a bouncy castle and activities for the children at the event which welcomed the mayor of Merton Councillor Agatha Akyigyina and Wimbledon MP Stephen Hammond as part of the day.
