I will preface this by saying, I would prefer it to stick to opinions and comments as to what you would or would not do in your own classroom. The last discussion turned more religious based and I understand that can quite often be a heated topic, but we can continue to be respectful of one another. I do not have very many religious actions in my classroom, but I do tend to throw up a prayer or two every once in a while. My students may see me make the action where I put my hands together and say a silent prayer (not often, but occasionally). Sometimes it is done in fun and sometimes in a serious manner. My students know that I believe in God, and they know that I go to church, so they are not at all suprised to see these actions. I would also believe that what you say and how you act in this regard could be different based on the demographics of the students you work with. I know in my area there is a significant amount of students who attend church, so parent issues with this would be much less likely.
