Symmetry and "Symme-Trees"

The first graders have been learning about Symmetry in math. To help make a "math-to-self" connection, we practiced finding the lines of symmetry of all kinds of classroom objects, including each other! Here is a picture of Haydon modeling his symmetry with a ribbon "line."

Next, we practiced folding a rectangular sheet of paper in half to make two symmetrical sides. Cutting along the folded side in a zig zag shape, we ended up with Christmas Tree shapes! The kids traced the fold to mark their tree's line of symmetry, and decorated them as symmetrically as they could. Our forest of "Symme-Trees" is hanging in our hallway and on our door!

And another...

And another!

The first graders are having fun finding the lines of symmetry in all kinds of objects!
