This virtual manipulative can help students visualize the golden rectangle. It shows how a set of golden rectangles is generated by using the golden ratio (the ratio of the longer side to the shorter side of a golden rectangle) to create smaller golden rectangles within an initial rectangle. The size of the initial rectangle can be varied, and the center of the spiral generated by the applet can be seen. Instructions for using this online manipulative are included on the site, as is a link to the NCTM standard for geometry. Copyright 2005 Eisenhower National Clearinghouse
