Symmetrical Designs with Pretzels and Marshmallows
Fifth graders create designs that have lines of symmetry using pretzel and marshmallows. In this symmetry design instructional activity, 5th graders work in groups using graph paper, rulers, and toothpicks to plan their own lines of...
Curated OER
Are We the Same?
Students 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.

Reflecting a Rectangle Over a Diagonal
Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.
Curated OER
Congruent Segments
The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another.
Curated OER
Geometric Transformations
Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.
Curated OER
Magnificent Mandalas
Students examine the principle of radial symmetry and apply it to an original mandala design. They draw a design using organic and geometric shapes, repeating the design symmetrically around the paper.
