**Ellipse Paper Folding Activity**

__Directions:__

1. On a piece of wax paper, patty paper, or transparent paper, construct a circle using a compass or circular shaped object.

2.
Label
the center of your circle A.

3.
Create
another point INSIDE the circle, not too close to the center.

4.
Label
this point F. (This is your focal
point.)

5.
Fold
the paper so that point F is anywhere on the circumference of the circle. Make a crease in the paper.

6.
Open
the paper and place point F on another point on the circumference of the circle. Make another crease in the paper.

7.
Continue
this process many times around the circle.
(It is sometimes easier to slide the point around the circle, making
creases every few millimeters.)

8.
Once
many creases are made, an ellipse should appear within your original
circle. (If you cannot see an ellipse
yet, continue folding, making your creases closer together.)
