Gather the materials.
Place the glass upside down on one of the boxes. Use the pen to trace around the glass to make a circle.
Use the craft knife to cut out the circle. Repeat this process with the other boxes. Make sure to save the round circles!
Paint the box with a white base coat. (A white base coat will help brighten the colors!)
Paint the boxes and the circles in different colors!
Add point scores to the circles and glue each one to a box.
Line up the boxes and get tossing! Who will get the biggest score?
