Essential Question
How can we use origami to model different
types of
symmetry?Slide3
Students will learn the 3 different types of symmetry (Reflection, Rotation and Translation), and then demonstrate their knowledge by creating a “Symmetrical Origami Art Project”
Students will become familiar with Origami as a Japanese art form; and they will master some of the folding techniques (turning a rectangular paper into a square paper without a ruler, and making sure a fold is lined up perfectly)used in this Japanese form of art, which will also be demonstrated in their Origami art project
Students will use the 4 explicitly taught Origami folds (kite, skinny kite, triangular 1 and triangular 2) to create an artwork that reflects the different types of symmetry (more specifically reflection and rotation symmetry)

Vocabulary
Symmetry-
when one shape becomes exactly like another if you flip it around, slide it, or turn it
.
Reflection Symmetry —when you fold a 2-D figure in half, the two parts will match up perfectly; also known as mirror symmetryRotation Symmetry-
t
he
image/figure can be turned a certain amount and look exactly the same; also known as radial symmetryTranslation Symmetry- moving an object to the right, left, up, down or diagonallyLine of symmetry- divides a figure into two equal halves (can be horizontal, vertical or diagonal)
Origami-
the Japanese art of folding paper into decorative shapes and figures
Fold-
to bend something over on itself so that one part of it covers
another
Kite Fold-
a fold that looks like a kite
Skinny Kite Fold-
a fold that looks like a skinny kite
Triangular Fold-
a fold that looks like a triangleSlide5
Reflection Symmetry
Also known as
“Mirror Symmetry”
When you fold a 2-D figure in half and the two parts will match up perfectly
Example:
Non-example:Slide6
Line of Symmetry
Divides a figure into two equal halves (can be horizontal, vertical or diagonal)
A
shape
can have more than one line of symmetrySlide7
How
many
lines of symmetry?
Where
are they?Slide8
Rotation Symmetry
Also known as
“Radial symmetry”
The
image can be turned/rotated a certain degree and look exactly the
same as it originally didSlide9
Which shape is
not
an example of rotation symmetry?Slide10
Translation Symmetry
Moving an object to the right, left, up, down or diagonally
Your
initial
shape does not moveThe translated shape is the one that is movedThe translated figure may not be rotated or flipped!
Correct:
Incorrect:Slide11
Which option
shows
translation symmetry?Slide12
History of Origami
Origami-
The
Japanese art of folding paper into decorative shapes and figures
The word “Origami” comes from the Japanese words oru (to fold) and kami (paper)Paper folding in ancient Japan was used only for religious purposesEarly 1600’s-paper folding became
a recreational activity as well
Late 1700’s- first written instructions for paper folding appeared
Origami was/is a huge part of Japanese cultureIt is now an art form used all over the world!Slide13
ExamplesSlide14
Origami Folds
Kite Fold
2. Skinny Kite Fold
3. Triangle Fold
4. Triangle Fold #2Slide15
The Kite Fold
Step 1:
Fold the square paper in half to make a triangle
Step 2:
Take outside corners and line them up with the crease that you made in the middleSlide16
Step 1:
Make regular Kite fold
Step 2:
Take outside edges and fold them towards the center once more
The
Skinny Kite
FoldSlide17
Triangular Fold 1
Step 1:
Fold Square in half (hotdog style)
Step 2:
Fold paper in half again to create a small square
Step 3:
Open fold once; Take the bottom corners and line the edges up with the fold line you createdSlide18
Triangular Fold 2
Step 3:
Squish flat!
Step 1:
Fold the square in half diagonally to make a large triangle. Open it, and fold it the opposite way. Open again.
Step 2:
Push two opposite triangles together and pinch the topSlide19
Symmetrical Origami
You will create a symmetrical design using the origami folds you make
