Review Geometry Week
Fifth graders participate in a review game of geometry topics. For this geometry lesson, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to complete...

Measuring Pattern Block Angles
Sixth graders identify various angles by using pattern blocks. In this measurement lesson, 6th graders find out how many degrees are in each of the different angles of the various pattern blocks.
Curated OER
Patchwork Quilts
Fourth graders examine about traditional quilting patterns, the symmetry in such patterns, and practice creating patterns of their own. They design a quilting pattern, and groups make colorful "patches," of a pattern. They assemble the...
Curated OER
Creating Tessellations
Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.
Curated OER
Congruent Triangles Postulates
Students discover three lettered postulates that prove triangles congruent.
Curated OER
Seeing Double
Students develop an intuitive definition for symmetry after viewing a PBS video. They examine asymmetrical patterns and demonstrate their knowledge by changing them to symmytrical.

More No-Three-In-A-Line
Fourth graders read Mary's problem and make sure that they examine it.
After some discussion, let the class work on the problem in their groups.
They then take turns in putting a picture of their arrangement on the board.
Curated OER
No-More-In-A-Line
Young scholars and teacher discuss square windows and their symmetry. Students work on the problem given and discuss any difficult ideas. They work in groups to use a systematic approach to get all possible answers.

Harnessing the Wind for Electricity
Ninth graders explain how wind can produce electricity. In this geometry instructional activity, 9th graders construct their own pin wheel turbine and calculate its power. They discuss the pros and cons of using wind generator.
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.
Curated OER
Ship Shape
Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...
Curated OER
The Delta Flier
Students make calculations in order to construct a kite in the shape of an isosceles right triangle. In this kite instructional activity students calculate altitude of their flying kites using a formula.
