1. Plan It

A. Look for geometric patterns. The shoulder bag on page 291 of your textbook shows quadrilaterals and triangles as well as slides, flips, turns, and symmetry. You will make your shoulder bag designs based on geometric patterns. Your patterns should include:

• a quadrilateral
• a triangle
• a slide
• a flip
• a turn
• an example of line symmetry
• an example of half-turn symmetry

B. Prepare your grid.

• Cut the grid from six sheets of half-inch grid paper.
• Tape the papers together to make one long sheet of paper.

Grid preparation completed

2. Put It Together

A. Start your design.

• Have a group member draw one of the geometric figures listed.
• Try to use each geometric figure at least twice.
• The next group member will chose another figure.
• Continue this process until you feel your group's shoulder bag pattern is complete.

3. Wrap It Up

Add other designs. If your group wishes, add designs that use other geometric shapes. Color the entire design.

4. Discuss Your Results

• Are the geometric figures identified accurately?
• How well did you use your knowledge of slides, flips, turns, and symmetry?
• Are the geometric figures in your design clearly shown?
• Did each group member contribute to the pattern?
• Can you find examples of the geometric figures in another group's design?
