• The figure at the right uses pizza models to represent fractions and mixed numbers. The gray circles are pans used for serving pizza. Each colored wedge is a slice of pizza.
• On the first line, one pizza equals 10 slices. In other words, each slice is 1/10 of a pizza. The single red slice models the number 1/10.
• Click the gray wedge above the red slice to show 2/10. Moving counterclockwise, click on the gray wedges to model the fractions 3/10, 4/10, , , all the way up to 10/10, which is 1.
• Click on the gray pan to the right of the red pizza to model fractions between 1 and 2.
• The second line models the mixed number 3 5/6 by using green pizzas cut into six slices. Each slice is 1/6 of a pizza.
The third line models the 'improper' fraction 18/7, which is 2 whole pies plus 4/7 of a third pie. This is the same as the mixed number
• Keep on clicking until you are comfortable with the pizza model of fractions and mixed numbers.
