Writing Equations for Parallel Lines
Acquaint your class with the concept of parallel lines. Learners watch a PowerPoint presentation about how to write equations of parallel lines. Their understanding of linear equations and slope is taken a step further by the exercises...
Curated OER
ABC's Transformer
Fourth graders design their own letter graph, and then produce the resulting graphs after a translation, reflection, and rotation. After a review of vocabulary, 4th graders create their graphs using crayons.

Exploring Trigonometric Ratios
Learners calculate the different ratios using a right triangle. In this trigonometry activity, students identify the sine, cosine and tangent of each side. They find the missing angles using the different ratios.

Exploring Angle Pair Relationships
Young scholars investigate the relationship between angles of triangles. In this geometry lesson, 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.
