Plans are for the games to be played at Cass' auxiliary gym, a 450-seat facility across the hall from the main gym.
Jamie Horton, varsity team head coach, said the Cass High and Junior Varsity teams will entertain their counterparts from Trion at 6 p.m. and 7:30 p.m. Cass Middle will host Excel Middle around 4:30 p.m.
Horton said his players are excited about being the first to play basketball at the new school.
"It's a great honor for us," he said. "It's also nice to be the featured event."
"We're calling it Girls Night Out. A lot of times our girls teams are kind of overshadowed. This will show everybody that girls can play and these will be good games to come out and watch."
He said Trion's coach is familiar to Bartow County residents. Josh Cowart, who directs the program, is a former coach at Excel Christian Academy and lives in Adairsville.
He said Cowart is fielding a team that should make some noise when state playoffs begin.
"They went to the state playoffs last year and I believe every starter is back from that team," Horton said.
He said Cass also is beginning to come together.
"We are starting to see some progressions with the way we're playing," he said. "We're hoping things will pick up and we'll start winning some ball games here."
Horton said the event also gives the school a chance to showcase its JV and middle school programs.
"Burt Jackson, our middle school coach, does a great job for us," he said. "We're beginning to see that in the play of our JV girls."
He said Melissa Winters, JV coach, also is taking those players a step further as they prepare for varsity play.
Horton said fans attending the games should come to the new school's main entrance and go to the student parking lot near the football field.
"There's a huge stairway that will take them to the gym," he said, adding signs will direct fans to the gym.
