Tenth graders explore the exterior and interior angles of triangles. They use a theorem in order to prove a theorem about all polygons. Students use the theorem and its applications to find the angles of different types of triangles.

Seventh graders find the perimeter and area of triangles.  In this finding the perimeter and area of triangles lesson, 7th graders find the perimeter and area of triangles given two sides.  Students find the missing side by...

Middle schoolers complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a...

Sixth graders use geoboards and dot paper to experiment with geometric concepts. In this geometry instructional activity, 6th graders complete four activities using geoboards or dot paper including naming points on a coordinate plan and...

Pupils develop an understanding and enjoyment of math concepts and cultural awareness by working with tangrams.

Learners study patterns. They construct growing patterns using pattern blocks and isosceles right triangles. They verbally describe the patterns and state the rule that describes the relationship involving the number of pattern blocks...

Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.
