Tonal gradation with circles

A tonal gradation is defined as value steps going from light to dark. In this exercise the students of Grade 7, have painted the tonal gradation of a color of their choice, showing the steps in strips of colors. This instructional painting was made less boring with a little trick: we cut out two circle from the painting and then we pasted them on a black cardboard, leaving a small strip of black shadow under the circles, in order to make them seem in relief!
