Learning to fold origami can be fun.  To fold the Chinese Star the students were given instructions such as:

bulletCreate the x- and y- axis
bulletFold the line y = x
bulletFold the line y = -x
bulletTake the highest point on the line y = x and bring it back to the origin
bulletTake the highest point on the line y = -x and bring it back to the origin
bulletFold this new figure along its line of symmetry
bulletPush at the right angle to create a parallelogram.
bulletWhen the 8 unit pieces are folded I then gave them instructions on how to put the eight pieces together to form the octagon.  When this figure is folded correctly the figure will collapse into a Chinese star.
