My school had a little nursery rhyme would use to say grace before lunch everyday. This was a public school btw, not a christian academy or anything like that.The Bible is not being pushed in schools.
It depends where you are from. I am from the blackest part of alabama as far as i can remember. The schools would do a morning prayers during the morning Pledge of Allegiance. During every school functions someone would be saying a prayer over the said function. Majority of my school teachers was either a pastor, first lady or deacon at somebody church. We also celebrated all of the christian holidays. we also had different version of the bible in my schools' library
God is Great
God is Good
Let us thank him for our food
By His hands we are fed
We thank You for our daily bread. Amen.
