Allowed, but not required (assuming the school is secular)
It shouldn't be part of a daily routine.
If they want to pray, then let them. If they don't want to pray, don't force them.
Allowed but very discouraged.
Yes, it is protected by the 1st Amendment.
Absolutely, But not forced or guided. If an individual chooses to pray on their own that's their own right. If its forced or guided then nope.
It is allowed, but teachers can't force it on students. I had a family friend who's daughter was sent to detention for not praying before their lunch (she was in 3rd or 4th grade, I believe)
It's a violation of the first amendment.
Ridiculous. If you want to pray, go to a church or a mosque or your religious temple. A school is a place to learn. Not pray. Stop abusing your rights.
No, Violation of the 1st amendment.
