The radial symmetry has elements identical and symmetrical, relative to a central point, such as we can observe in the shape of snow crystals or in the disposition of the petals in a flower.
After drawing a square with its medians and diagonals, we have drawn three curved lines and two straight lines within a clove of the square. These lines were traced on tracing paper with a soft pencil, and drawn again on each sector of the drawing with the pencil. At the end of this first phase we got a drawing in radial symmetry, and we redrawn it with a colored marker. In the second phase we colored the drawing with colored pencils, choosing only 4 colors and paying attention to color the areas symmetrically. With colored pencils, we’ve created shades by varying the pressure of the pencil. We have created these masterpieces with the 7th grade classes to introduce the theme of the gradient and value.
