Directions for Making a Design

Work in pairs to make a symmetrical design.

• 1 Make a horizontal line of symmetry across the center of Triangle Paper (S44). One side will be the first partner's side; the other will be the second partner's side. Work only on your own side of the line.

• 2 The first partner places a shape on the triangle paper, touching the line of symmetry on one side.

• 3 The second partner puts the same kind of shape in the mirror-image position on the other side of the line.

• 4 The second partner places a new shape on the paper on the second partner's side. The shape must touch either the line of symmetry or at least one corner or side of a shape already placed.

• 5 The first partner puts a shape in the mirror-image position of the second partner's shape.

• 6 Continue, until 12 shapes have been placed in all.

• 7 Set the first design to the side, being sure to keep the pieces in place, and start a new design on a separate sheet of Triangle Paper, following steps 1–6.

• 8 After you finish the second design, each partner colors one of the designs. Use colors that match the Power Polygon pieces.
