Supplies: ruler, compass, eraser, HB pencil, primary and secondary colour pencils, and
8 1/2 x 11"
white paper

Instructions: Create a design using six geometric shapes (3 different shapes; repeat each one once). Assign one different primary colour (red, blue and yellow) to each of the 3 shapes. After deciding on an arrangement that allows each shape to overlap another, lightly draw the shapes with an HB pencil. Avoid having 3 shapes overlapping each other in the same area.
With colour pencils, colour the shapes with the assigned primary colours and colour the overlapped areas with a secondary colour (green, orange and purple). The secondary colour assigned to a particular overlapped area should be the colour resulting from the combining of the 2 primary colours assigned to the shapes. Eg. the area coloured orange is where the red circle overlaps the yellow triangle.

Variation: This lesson can involve organic shapes (free hand) instead of geometric.
