Ah, I see the problem, Witless. You don't understand what the word MAY means. Got it.<quoted text>
How likely it is makes no difference. What if there are even 10 different religions represented by the children? Again, how much time will be left for actual school work (you know, the reason the teachers and children are THERE in the first place?) when the teacher has to settle down the students who will be praying, AND those who won't, each and every time?
You never answer my other question, either. Why do you think prayers must be said out loud? Don't Christian prayers work if they're not spoken out loud where others must also listen to them?
