Construct and Measure Lines, Segments, Rays, and Angles Using Geometer's Sketchpad
Sixth graders construct points, lines, rays, line segments and angles using Geometer's Sketchpad, label all points and measure each constructed item, print their constructions, and complete question sheet to demonstrate understanding.
Families of Parallel Lines and the Circumference of the Earth
How do you fit a tape measure around the Earth? No need if you know a little geometry! Pupils begin by extending their understanding of the Side Splitter Theorem to a transversal cut by parallel lines. Once they identify the proportional...

Looking More Carefully at Parallel Lines
Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...
