Shapes that touch at corners are filled in with solid color. Make sure all shapes that meet at the corners are filled in like a regular checker board. If time permits, or if an additional day of discussion is available, experiment with creating checkerboards that use only straight lines, or only curved lines. Make sure that if curved lines are used, the student start at one edge of the paper and not lift their pen until the pen goes off the paper again. Assessment Teacher reviews each student's work to verify that each project meets with the minimum lesson requirements.
All straight lines are random.
At least three circles of different sizes. Shapes that touch at corners are filled in with solid color. Check craftsmanship, quality and neatness of line and fill.
