Green construction paper,or poster board,tape,scissors,Christmas stickers,or various Christmas cards,and box cutter.
The idea is to make a Christmas tree shape out of the green construction paper or poster board, which ever you pick. Make the tree large enough to cover the Christmas card. Make 24 doors to be opened during Advent, using the box cutter for easy cutting. Tape the Christmas card under the tree shape firmly. As the doors open the picture from the Christmas card or Christmas stickers is revealed. Prepare Christmas tree shapes prior to class for easy assembly in class. Ages 4 and up. Approx. 10 mins.
