Step 3: Hot glue an old CD (blank side up) in the center of the circles, making sure it is centered.
(Notice that there are no circles drawn around the CD in the photo below? I realized much later that it is easier to draw the circles BEFORE gluing on the CD.)
Step 4: Using the fine tip permanent marker, draw a dot in the center of the CD.Line a ruler up with the dor and draw a line across the CD.
Step 5: Find the hole at the bottom of the protractor (shown by the arrow in the 1st photo below) and line it up with the dot in the center of the CD. Make sure that the black lines on the protractor's bottom line up with the black line that has been drawn across the CD (shown in 2nd photo).
Step 6: Keep the protrator in this position and make a mark at every 30 degrees (30, 60, 90, 120, 150, 180). Flip the board around and repeat steps 5 and 6 so that the CD is marked every 30 degrees all the way around, as shown in the 2nd photo below.
Step 7: Using the ruler, connect the marks at 90 degrees so that you now have perpendicular lines (math term!)
Step 10: Repeat this same design in the remaining sections. Remind students that the design uses Radial Symmetry (math term!), meaning that it is the same all the way around. Again, use the circles as a guide to line up the design.
Step 13: Once the design is decided upon, trace the lines to be kept with the fine line permanent marker.
Step 14: Continue the design in the remaining sections, making sure to line everything up as carefully as possible. Use the guielines to help space things out. (Oops! Someone got antsy about coloring before taking the photo!)
