Curated OER
Geo Jammin' By DeSign - Day 3, Lesson 13: Reflections
Students use current knowledge to predict the meaning of line of symmetry. They explore symmetry using mirrors.
Curated OER
Geo Jammin' By DeSign - Day 3, Lesson 14: Mirror, Mirror on the Wall
Young scholars explore characteristics of symmetry, write a definition, and locate the line of symmetry on a shape.
Curated OER
Geo Jammin' By DeSign - Day 5, Lesson 24: Read All About It!
Students listen to The Important Thing About Quilt Design and rewrite an original version using geometric terms.
Curated OER
Geo Jammin' By DeSign - Day 5, Lesson 25: Geo Jungle
Students search the school grounds for examples of symmetry in nature. They bring examples back to the classroom and write about them.
Curated OER
Boarding of Symmetrical Shapes
Second graders use geoboards to model polygons and to practice finding lines of symmetry.
Curated OER
Upside Down and All Around
Second graders discuss what a line of symmetry is, then demonstrate how to fold shape cutouts to generate lines of symmetry. They demonstrate slides, flips, and turns with objects, and write explanations of changes they observe in pictures.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
