Common Core Standard 4.G.3
FALL is a season of Transformations
Shapes with Line Symmetry have a line or a fold
that makes two reflecting parts.
Looking at symmetrical sides, each side will look
exactly the same and each point will have a
corresponding reflection point on the other side.
3
Extension Tape a pipe cleaner on the fold, as
the stem of the leaf. Tape four or six of these
leaves to a paper towel cylinder or rolled piece
of brown card stock paper. Continue the
discussion of symmetry, by placing the same
amount of leaves on both sides of the tree.
Connect this to your science lesson by saying
that due to wind, parasites, etc. trees are not
usually symmetrical.
Print the next slide onto fall colored paper so
it can be folded on the dotted line. Cut on the
solid lines. DO NOT cut on the dotted line.
Unfold the paper to see the finished leaf.
Discuss the symmetry line of symmetry. To
decorate, place items that might be found on
leaves on each side of the fold, making it
symmetrical (see last slide). Staple a craft
stick to it, to make a fan.
