Learners use the Internet to learn about transformations and tessellations.  In this geometry lesson plan, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and symmetry. ...

Third graders demonstrate their mathematical knowledge of symmetry and reflection using congruent geometric shapes while working as an artist and mathematician looking at a medieval-styled stained glass window.

Students 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.
