All the drawings that are affected are instantly updated, so that the effects of different patterns of rotations can be seen quickly. The user can also edit the unit square itself and see the effects on whatever designs (2 X 2, 4 X 4, or 8 X 8)

For example, the teacher could say: "For what kinds of unit squares will these two sets of arrows produce the same final quilt? " Another set of investigations involves working backwards.

it allows children to express their own creativity in a way that is not ordinarily associated with the study of mathematics in part, students decide what is "right" based on their own aesthetic sense; and (c) it uses modern technology and sophisticated software to enable students to explore mathematical concepts heretofore inaccessible through traditional means.

Characteristics of the medium response: The child understands how the software operates and can create interesting quilts with it. There is not, however, a systematic approach used in exploring the effects on the final quilt of individual changes in the arrows.
