I just love the Christmas holidays. This year I would like to have an advent calendar in the classroom before Christmas. I'm thinking of buying a cheap artificial Christmas tree and buy a full set of decorations (no religious shapes or forms, just circles), and have one child each day hang a decoration on the tree. No religious songs or anything by the three, just for the decoration. I do have several religions represented in my classroom but I'm thinking a Christmas tree is more a cultural common symbol than a religious one. Any concerns about this that I should be aware of?
