Hundreds of students turned market traders for the day as their business ideas bore fruit at a business park.
The young entrepreneurs ran 40 stalls, selling everything from glass paintings to photographs, as part of the Skills to Shine Summer School.
The Make a Pound Grow challenge has given them the self confidence to draw up business ideas which they are passionate aboutLindsey Dunn, chief executive at Skills to Shine
More than 150 pupils from Burnside Business and Enterprise College, John Spence Community High School, and Longbenton Community College took part in the event at Cobalt Business Park.
The 11-year-olds spent two weeks learning how to turn an initial £1 outlay into a viable business idea on their summer school course.
Skills to Shine works with youngsters leaving primary school for secondary school during the summer break, preparing them for change.
Lindsey Dunn, chief executive at Skills to Shine, said: “The young people have really taken up the challenge to create a host of businesses.
“The Make a Pound Grow challenge has given them the self confidence to draw up business ideas which they are passionate about.”
Lynn Cramman, business development manager, at Cobalt added: “We are delighted to welcome these young entrepreneurs to Cobalt to grow their £1s.
“We have been really impressed with the project and the children’s attitude to business and hope the experience will enthuse them for their future careers”
All the money raised from market stall sales on the day will go to the WildHearts foundation providing small loans and business training to people living in some of the world’s poorest communities.
