1. Students can follow an assortment of instructions available all over the internet. I have found that the best way to approach it is to do a full petal with students simply watching the teacher demonstration first. Here are two resources I've used in learning how to make the orgami flower: http://foldingtrees.com/2008/11/kusudama-tutorial-part-1/, and http://www.youtube.com/watch?v=eQ5aqld7XS4
2. After watching the teacher demonstration the students do the lesson with the teacher who is pointing out the fractions, and math vocabulary along the way.
a. Fold the square point to point keeping the color visible after the fold, thus folding the paper in half.
b. Bring the two corner points up to the center point of the triangle to form a diamond shape.
c. One at a time bring the inner center folded edge to the outside edge, repeat with the other side.
d. Open one side of the fold and crease it so it has the appearance of a kite, repeat with the other side.
e. Fold the tip of the ‘kite’ shape down, repeat with the other side.
f. Using a sturdy glue, preferably hot glue, attach the two outer edges to create one fifth of the entire flower.
g. Repeat these steps to create an additional four flowers.
3. At this point the teacher can explain that they have now created 1/5 of the necessary petals to get to a whole flower. Discussion is also focused on symmetry in the folding, as well as precision and craftsmanship.
