Creating and Destroying Symmetry
Students study the types of symmetry that appear in different basketball symbols. They point out changes that rotate symmetry from one type to another.

Third graders find all the lines of reflection symmetry in a given shape, identify the order of rotational symmetry of a given shape. They create designs which have reflection symmetry, rotational symmetry (orders 2, 3, 4, 6) and...
Pennsylvania Department of Education
Length and Perimeter
Third graders explore tessellations and the spatial concepts used in creating them. For this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations. Students become familiar with the vocabulary...
Curated OER
Fold and Cut
Second graders explore line symmetry and the names and attributes of two-dimensional mathematical shapes. They study the context by folding and cutting out shapes to make a series of mathematical shapes.
Curated OER
Transformation
Third graders investigate symmetry by reflecting objects in different angles. In this geometrical transformation lesson, 3rd graders define the terms translation, rotation and reflection in order to physically turn geometric...
Curated OER
Keeping in Shape
Third graders describe patterns in terms of reflection and rotation symmetry, and translations. They design and make a pattern which involves translation, reflection, or rotation. They demonstrate why a given tessellation covers the...

Let the Light Shine Through!
Students display knowledge of line of symmetry by designing a geometric stained glass window pattern.

Tessellation Sensation
Geometers investigate patterns and symmetry, and examine the artwork of M.C. Escher on the Internet. They compare his style to the floor and ceiling tiles in the classroom. If you have ImageBlender™ software, you could have your class...

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.
Curated OER
Building Big and Strong
Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.
Curated OER
Tessellations
Fifth graders investigate the relationship between math and art by examining patterns and polygons.They examine how polygons make up the patterns that form tessellations, and determine tessellations that occur in nature. Finally, they...
