The 2017-18 academic year started well before the first day of class for many local students and teachers.

Across Long Island, schools held everything from back-to-school barbecues to team-building activities to campus and community tours.

In Freeport, the high school hosted an orientation for incoming freshmen and their parents, with administrators and department leaders explaining the many programs available to students. Members of the school’s peer leadership program led freshmen on a tour of the building and conducted small group discussions in various classrooms.

“We have tried to make possible anything and everything you can think and dream of here,” Superintendent Kishore Kuncham said of the school’s academic opportunities.

In Mineola, Chaminade High School hosted a 3-C Week of parent and student orientations for the Class of 2021, a chance to meet with homeroom moderators and senior leader volunteers, and a social in the school’s Activity-Athletic Center. The incoming freshmen also received iPads, locker assignments and gym class uniforms.

In Bethpage, 25 new educators assigned to district schools attended a daylong orientation that began with breakfast and included a bus tour of the community, with stops at local businesses such as Gold Coast Studios, where they toured the set of the CBS sitcom “Kevin Can Wait.”

In Glen Head, North Shore Middle School hosted an orientation and barbecue for incoming sixth-graders that included a tour of classrooms, practice in opening lockers and “fun meet-and-greet games,” school officials said.
