Problem Description Sheet:        Show Me One-Quarter            Introduction: You and three other people wish to share a square-shaped pizza. Each person is to have an equal amount. You divide the pizza into four equal parts so each of you will have ¼ of the pizza.  Problem: Show as many ways as you can think of to divide the pizza into four equal parts. Colour the ¼ of the pizza that you get to eat. Pretend the square drawn to the right is the pizza. Make as many of these squares as you need. Use paper-folding, cutting, or drawing to show ¼ in as many ways as you can. Materials: duplicates of the square pizza, pencil, ruler, scissors, calculator Extra Questions: Repeat the activity showing 1/8 (the equal sharing among 8 people). Repeat the activity showing 1/3 (the equal sharing among 3 people). Which was easiest (showing 1/4, 1/8, or 1/3)? Which was hardest? Why do you think that was the case?
