Christmas Tree Lesson Plan! Christmas trees can be a great tool for catechesis whether at home or in a classroom. This lesson plan will help you unpack the symbolism of the Christmas tree customs with your students. They will be able to see their trees in a new way and even be able to teach their parents about what Christmas trees are meant to remind us of during Advent and the season of Christmas.
