### Designs in the Coordinate Plane

by Russell F. Jacobs

This activity book, along with Symmetry in the Coordinate Plane represent a slight departure from our other "design" books. The student is required to work a set of math exercises in order to define a set of ordered pairs of numbers. These ordered pairs are then located as points on a coordinate plane. As each student follows directions to connect the points, a geometric design, sometimes surprising, emerges. In some of the activities only half of the design is completed by plotting points. Students are directed to complete the design based on the principles of symmetry. All of the designs involve points in the four quadrants.
