Find the Missing Angle
This one activity requires young geometers to pull together information they are currently learning with things they have learned previously. Here they rely on understanding something about parallel lines, alternative interior angles,...
Curated OER
Geometric Angles
Students explore angles and their use in Geometry. Students investigate three different kinds of angles: obtuse, acute, and right angles through an online activity. They identify pairs of angles with special relationships: vertical,...
Curated OER
Exploring Angle Pair Relationships
Young scholars investigate the relationship between angles of triangles. In this geometry instructional activity, students identify properties of right and non-right triangles. They differentiate between vertical and supplementary angles.
Curated OER
Exploring Angle/Pair Relationships
Students find missing angles and sides of triangles. In this geometry lesson, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.

Module 6: Trigonometric Functions
Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Let the Sun Shine In: Energy Conservation
Students create a project applying their math skills as they discuss energy conservation. In this geometry lesson, students define vocabulary relating to the environment and energy conservation. They construct a building that allow lots...
