Other solution:

maybe you can use the constraint: min gap between a set of activities, with a tag for sports and maths.

No, because Math then immediately after it Sports should be allowed, but your solution denies this.

i would like to add  my humble contribution to  explain how  i fixed the probleme of  sport ..it is known that in algerian schools  sports is  two  hours either in the  last two  hours of the  morning  or the last two hours  of the  evening thus  i tried  the  constraint " preferred starting times":and  actually i  submitted  the  starting  times according to eqch stream and  level and  actually  it was  a success .

That hint won't help the topic starter. He has got 30 classes and only 2 gyms.
That mean he need 30:2=15 end hours.
But a week has only 5 days. So even with morning and afternoon prefered times there are only 2*5=10 end hours.
Sadly 10<<15. So your suggestion is impossible.

Livius suggestion is correct. With his suggestion it is possible (if he doesn't have got nearly only subject math. But i bet he has got also a lot of other subjects).

well dear Volker Dirr sometimes it is  possible  especially if you have some  classes  which have  two or more  free  hours i mean here that  a teacher  may have  two  classes in the morning or  two classes  in the afternoon even if they  get sport  in the morning they may get  home at 10.00 or 15.00 with no  lectures  at  all and this is  possible  in highschools with  some  streams i joined  two  pics

ah. ok. My students are not allowed to have free gaps by law. I sadly assumed he has got the same law. My timetables are also always 100% filled in the morning. If he doesn't have got that law, than at least 5 classes need gaps if you use evening and morning timetable. If he use morning timetable only, than there must be at least 20 classes with gaps. I am not sure what is more worse: gaps or math after sport.
