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
Transformations Using the Geometer's Sketchpad
Students discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.

Symmetry of the Southwest
Fourth graders examine mirror symmetry. In this symmetry lesson, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

Sneaky Peeky Symmetry Book
Students examine lines of symmetry with different shapes. Then students create their own books of symmetry with different two-dimensional shapes on each page.
Curated OER
Boarding of Symmetrical Shapes
Second graders use geoboards to model polygons and to practice finding lines of symmetry.
Curated OER
Symmetry
Learners examine the concept of symmetry. They use photographs in front of a mirror to see symmetry. They write an explanation or drawing of how a mirror always produces a line of symmetry.
Curated OER
Symmetry In Nature
Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...
Curated OER
Turn Symmetry
Fourth graders observe geometric patterns to determine if they show rotational or point symmetry. They participate in the a demonstration instructional activity with a triangle. They create their own designs that show rotational or point...
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson plan and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
2D and 3D Shapes
Have your class use online activities to recognize the names and properties of 2D and 3D shapes. They will listen to their teacher describe a mystery shape and try to guess it. Additionally they will watch clips online about a 2D shape...
Curated OER
"Polly"gon Pockets
Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...
Curated OER
Interpreting Lao Design: Painting
Students examine Lao art techniques and practice replication and modification of Lao designs. Maintaining a symmetrical image, they embellish designs with imagery and background color. They discuss the students' works and note the...
Curated OER
Transformations
Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...
Curated OER
Punch Patterns
Fifth graders duplicate patterns, guess pattern results and identify the symmetries created. They are given an instructional handout, 5th graders replicate the patterns demonstrated by folding the paper and punching the appropriate...
Curated OER
Are We the Same?
Pupils define and discuss symmetry, line of symmetry, and congruency. They cut shapes out of construction paper, identify the line of symmetry, and if they are symmetrical and/or congruent.
Curated OER
Pattern Matching
First graders examine how to determine the lines of symmetry in pictures, shapes, and patterns by completing the lessons in this unit. They make patterns that show a line of symmetry and describe it using their own language.
Curated OER
Symme"tree"
Students practice drawing lines of symmetry after the teacher draws shapes on the board. They create a class symme"tree" using only symmetrical shapes to decorate it.
Curated OER
Symmetrical Journals
Students identify symmetrical shapes around their classroom and make symmetry journals. In this symmetry lesson plan, students make drawings of symmetrical shapes inside their journals.
Curated OER
Cutting Corners
Second graders examine two-dimensional shapes using their characteristics. In this shapes lesson, 2nd graders identify similarities and differences by using cut out shapes, diagrams, mirrors, and graphic organizers.
Curated OER
Whatever Floats Your Boat
Second graders make boats by folding paper. They identify and draw shapes made during the creating process and place lines of symmetry on them. They demonstrate their understanding by completing an activity sheet imbedded in this plan.
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
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.
