Exploring Special Segments in Triangles
Young scholars discover that four special segments have a common intersection point. They identify the position of the intersection point in triangles. They produce conjectures about areas of the divided triangles.

Downtown Landmarks: geometry on Firstside
In this geometry learning exercise, students look at a picture of downtown landmarks and identify different shapes, lines, and more. Students identify 18 items.
Curated OER
Fashion Day
Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Making Tangram Pieces by Folding Paper
Third graders follow directions to make a set of tangram pieces. After reading a story, they compare and contrast the differences between two-dimensional shapes. To end the lesson plan, they use the tangram pieces to create their own...
