Creating a teaching tool which shows the (daily) art steps makes it easier to "show and tell" how to do the various steps of a layered mixed media art project during a weeklong VBS. The visuals teach the children and also show the adult helpers how to assist the children. It requires four boards cut to the size the children will be using.
As you develop the project, the bottom layer goes on all four boards. The second layer goes on three boards; the third layer on two boards; and the final layer only on the fourth board. The graduated layers also helps kids see what they missed (and how they can catch up) if they skip a day of VBS.
