Geometer’s Sketchpad is a visual modeling and graphing tool that does the work of traditional graph paper, compass, straightedge, and other similar tools. Through visual displays and interactive adjustment of variables, it allows students to authentically investigate topics and concepts.
Teacher Kevin Thompson uses Geometer’s Sketchpad as an investigative tool in a number of lessons. This video shows a student assignment involving the geometry of a ferris wheel in motion. This video shows a student visualizing the solution to an assigned problem.
These videos shows a student activity manipulating an image using transformations from geometry and creating a sine wave
