Geometer 39-s Sketchpad -gsp-

While "Geometer" is in the name, the software’s utility extends far beyond triangles and circles. GSP is used to model algebraic functions

If you have access to a legacy copy, fire it up. Construct a simple segment. Find its midpoint. Draw a circle. Then drag it. geometer 39-s sketchpad -gsp-

Have you used Geometer's Sketchpad in your classroom? Do you have a classic .GSP file you cannot live without? Share your memories in the comments below. While "Geometer" is in the name, the software’s

The genius of lies in the "Drag Test."

You can find many pre-made mathematical investigations and student activity sheets on the Sketch Exchange community site. Find its midpoint

Developed by Nicholas Jackiw at the Geometry Center at the University of Minnesota and published by Key Curriculum Press (now part of McGraw-Hill Education), is a dynamic geometry system. However, calling it "geometry software" is like calling a telescope a "light collector"—it is technically correct but misses the grandeur.

GSP alumni include thousands of math teachers who say: “I didn’t really understand the centroid until I built one in Sketchpad and dragged it.”
