7.Have circles drawn on the board divided into 2,3, and 4 equal and unequal pieces. Leave 1 circle whole.
8.Call children to the board one at a time to point out a given fraction, reminding when necessary that fractions are equal parts.
9. Then give each child 4 Unifix cubes and have the students show fractional parts as you call them out. This can be done with the whole class showing the fraction or a few children at a time showing the fraction.
10.When the class has had enough practice, have children go back to their small groups.
11. Assign each group a size to cut: whole, ½, 1/3, and 1/4.
12.With teacher's help, the groups cut their pizzas in ½, 1/3, 1/4 or leave it whole.
