Created by a mathematics teacher artist, these materials for grades K to 9 teachers are from inservice workshops that illustrate how art and mathematics are intrinsically linked. The suggested activities aim to help the student develop a keener spatial sense and to discover geometric ideas. They also promote creativity and logical reasoning as the student investigates informally basic elements of linear and plane geometry. A demonstration version of Geometer's Sketchpad is included at the site to enable the user to explore some of the activities online. In a sample activity, Coffee Can Geometry, students create designs by following illustrations that show a sequence of steps for inscribing diameters, arcs, and other chords in circles.
Students construct a point in the center of a circle.
Next they use a clear, transparent cover of a coffee can to make arcs that intersect both the center and the circumference of the circle. The resulting designs include star, leaf, and flower forms. Additional materials such as scissors, construction paper, colored markers or pencils, glue, etc., are easily attainable. No specialized room facilities are necessary. To save and print out sketches you will need your own copy of the program.
