Line symmetry is all around us—from butterflies, to buildings, to your own face
in the mirror. Rotational symmetry is all over, too. You can see it in sunflowers,
hubcaps and sea stars. Snowflakes have line symmetry and rotational symmetry.
Let’s make paper snowflakes and explore.
What you need:
• Square sheets of paper (any size between 4”x 4” and 8”x 8” works well)
• Sharp scissors
Try this:
1. Fold the square of paper diagonally to make a triangle.
2. Fold in half again to make a smaller triangle.
3. Then fold into thirds. (This is the tricky part! It’s OK to try it and then re-fold until
you get it just right. If you want to use a protractor, each third should be 30o.)
4. Cut the top off at an angle. Check to make sure all the layers of paper are
the same size.
5. Now use your creativity! Cut away at the sides. Try different sizes and shapes.
If it is spring or summer, can you create a pattern that looks more like a flower
than a snowflake?
6. Unfold the paper. Can you see the rotational symmetry? What about the
shapes you cut out—are they symmetrical?
7. Use a marker to draw the lines of symmetry that you see.
