Tanner's Crossing School operates a very intensive intramural sports program, a system whereby all students in grades five to eight are placed on a team for noon hour sports. The intramural schedule is drawn up so that there will be no conflicts with the noon hour choir or band practises. Although they are not a part of the intramural program, grades one to four classes are also scheduled for regular noon hour activities.

The emphasis in intramural sports is on participation rather than winning. Points are totalled for the whole year and the team with the most points in June will have its house name placed on the Intramural Championship board. Each intramural house has three staff members and four students as leaders. Games are played between 12:15 and 12:40 and schedules are posted well in advance. Students are encouraged to check the schedules for the days they play, thus eliminating phoning home for lunch.
