Students investigate and perform reflections and symmetry. In this geometry lesson, students compare and contrast the relationship between reflections and symmetries.

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Sixth graders build figures out of tangrams. In this symmetry lesson, 6th graders view tangrams and identify the polygons included in them. Students divide into groups, identify their tangram pieces, define the lines of symmetry, and use...

Students perform translations and reflections. In this algebra lesson, students use the TI calculator to graph functions. They move the functions around on the coordinate plane using translation and reflection.
