Opening and synopsis:
“Butterfly wings have it. Triceratops had it. The word MOM has it.When you know what to look for, it’s easy to start…seeing symmetry.”
Symmetry is all around us: on our bodies and in plants, animals, the alphabet, art and more. Leedy’s dynamic illustrations make it easy for students to “see symmetry” on the page and in their world. Check out her book trailer:
Why I like this book: Symmetry is a math concept you have to see to believe. Leedy’s images clearly show both line and rotational symmetry and help students understand key concepts like “line of symmetry” and “asymmetrical.” Her backmatter is extensive and includes notes, activities, a glossary and an explanation of why symmetry is something students should know.
Resources: Seeing Symmetry includes two activities in the backmatter. There are instructions for making a Symme-TREE by folding paper in half and drawing a tree along the fold line. Students can cut out and decorate their tree for an example of line symmetry. She also has instructions for making a paint blot picture by putting blobs of paint on a sheet of paper. Children fold the paper in half one way and then the other to complete the picture. Leedy also has a wealth of resources (many free) on her TeachersPayTeachers Web site.
