1st Grade Shape Robots

1st graders are reviewing geometric shapes, in particular; square, rectangle, circle, oval, and triangle.  Students were to use geometric shapes to build their own robot.  All of their drawings were fabulous! I knew I wanted to add color to the drawings, but wasn't sure what would be the best route to not loose any of the wonderful details from the drawing.  I had a suggestion from a fellow art teacher and used tissue paper squares and water to add color.
