We held a "graduation" for the young ones who "next fall" would be "graduating" into our Rotation Model.
Their teacher and the pastor led the young ones and their parents over to a tour of the workshops. We had a few of the workshop teachers there. In the final workshop we had a "graduation cake" and some of the older students serving.
Of course, the young ones were familiar with some of the workshops, but we felt it was an appropriate sign for kids and parents to remember and enjoy.
We did something similar for our older elementary who were moving on to the youth class.
