The 250 youngsters - many playing the sport for the first time - battled it out in a special tournament at the Glasgow National Hockey Centre.
The £5.5million venue, situated beside Glasgow Green Football Centre in Kings Drive, will host the hockey competition at Glasgow 2014 Commonwealth Games.
Chairman of Glasgow Life and executive member for the Commonwealth Games, Councillor Archie Graham, joined sportscotland chairwoman Louise Martin to unveil a plaque marking the occasion.
They were joined by Glasgow City Building Construction Plant apprentice Ryan Doran who was one of 12 apprentices to work on the project.
A total of 12 schools played matches on the state-of-the-art synthetic pitches.
Abbie McMahon, 9, from St Thomas Primary, in Riddrie, said she had enjoyed playing hockey for the first time.
She said: "It is fun. This is the first time I have been here. It will be amazing to have the Commonwealth Games here, I want to try to come and see it."
Hayley Finn, 10, from St Michael's Primary School, was also trying out the sport for the first time.
She added: "My favourite part is when we are all trying to get the ball from each other at the same time."
The centre, Scotland's newest hockey facility, opened to the public on July 22. It was designed by Glasgow City Council's in-house design team and built by City Building.
Councillor Graham said: "We want Glaswegians, but in particular children, to lead healthy lifestyles and this is one of the ways of encourag-ing them - by bringing them along to these new facilities and letting them try out a sport.
"Most of them haven't played hockey before so it's fantastic to let them try out a new sport and see how enjoyable it is in a facility like this. Hopefully the legacy from that activity will be healthier people in Glasgow when they grow up."
The project, which was part-funded by sportscotland, features two water-based floodlit synthetic hockey pitches and changing facilities. It has 500 seats in its grandstand and an extra 4500 seats will be installed for the Games.
Ms Martin said the Glasgow pitches were the best and most up-to-date in the country.
She added: "It is a place where our national teams can come and train. It is right on the doorstep of a lot of clubs and they can all come in here for squad training.
"It can really benefit the game, both boys' and girls', throughout the country."
Ryan, 18, from Pollok, worked on the project for two years, arriving soon after the foundations had been laid.
Around 1.5billion people around the world are expected to tune in to watch the Games and Ryan said he was proud to have played a part in the construction of the venue.
He said: "It is exciting to see it all up and running and to pass by and say 'I helped build that'."
