Girls from Marion and Mattapoisett joined their Kaleidoscope dance and gymnastics teammates as they tumbled and twirled across the floor of the TD Bank North Garden on Friday during half-time at the Boston Celtics game.

While performing on such a large stage is something the dance team is used to, having performed at the Garden four times, this is the first time tumbling was worked into the routine and the gymnastics team was brought on board.

“The dance team started doing it and this year we invited the gymnastics team…just representing kaleidoscope as a whole,” said Kaleidoscope Director Michele Femino.

Femino Choreographed the routine, which is a jazzy number called “Hot Has Gotcha.”

Even though some of them have done this before, Femino says it’s still an exciting experience: “Who gets to go on the court?”

While they are used to performing in front of people at competitions, the crowd at the Garden is much larger than what they're used to.

Ten year-old Kate Erickson of Marion, who is on the gymnastics team, performed at the Garden for the first time this year. “It’s really cool that she [Femino] incorporated gymnastics,” into the routine said Erickson.

“I’m nervous and excited. Since we’re gymnasts we’re used to having a spring floor, now we’re doing back handsprings on the wooden floor.”

“It’s thrilling being there,” said 18-year-old dancer Katie McCarthy of Wareham, who has performed at the Garden four times before. “I’ve been nervous every time but once you get out there it’s not bad.”

She said that they’ve put a lot of hard work into the routine noting, “It took a couple months to put it together.”

For their next big performance, the girls will perform at a Providence Bruins game.
