 Pizza Pizzazz. In this three-role game, you serve as the chef, then assistant, and then customer. Will your pizza have enough pizzazz to please the customer? Today we are demonstrating a variation of the game where all three players play at the same time. Materials needed for this game include the dough, toppings, spinner, pen, and a paper clip. To begin, each player spins the spinner and writes down the number they spin. Each player is a chef and designs half a pizza using the number of shapes on the spinner. Your design can be as simple or complex as you choose. However, the chef is very busy and must leave the pizza half done for the assistant to finish. Each chef passes a half-done pizza to the player on their left. Now each player becomes the assistant. As the assistant, you now need to finish making the pizza. First, find the line of symmetry. Complete the pizza by making the empty half of the dough symmetrical to what the chef already designed. Once each assistant has finished a pizza, players pass the dough to their left again. Now roles change to that of the customer. The customer evaluates the pizza and determines if it is symmetrical. It is helpful to first discover the line of symmetry on the pizza before judging it. Once the customer judges the symmetry of the pizza, points are awarded. If the pizza is judged to be symmetrical, then the assistant for that pizza earns two points, and the chef for that pizza earns one point. If a pizza is found to not be symmetrical, the chef of that pizza earns two points, and the assistant of that pizza earns one point. That concludes round one. Players receive new dough to continue playing. Each round consists of a new shaped dough. The dough of round two is square, and for round three, it is heart-shaped. The previous steps are repeated each round. After all rounds are completed, the player with the most points wins. For helpful hints, create a visual for the line of symmetry with a pencil or a string. Another idea is to try to think of symmetry as butterfly wings when placing your toppings on either side of the line of symmetry. Some questions to think about. How can you tell where the line of symmetry is in the figure? Can toppings overlap on the pizza? How does the placement and number of toppings used by the chef make the game more challenging for the assistant? There are several possible variations for this game. One includes changing the shape of the dough. To increase the challenge, allow the chef to place toppings anywhere on the pizza. Then the assistant must define a line of symmetry and place toppings relative to that line. This game could be used to play with rotational symmetry. The chef could place toppings in only one quarter of the pizza. Then the assistant must use rotational symmetry about the center point to finish the pizza.
