The kindergarten classes go to the Public Garden in Boston and do the Make Way for Ducklings tour. When they return I like to make duck pond pictures with them. We focus on the difference between 'above' and 'below'.
I teach them how to draw ducks and make suggestions for what to draw under the water and above the pond. They trace in skinny sharpie, color with construction paper crayons, and then paint over the water with blue watercolor.
