## Beacon Lesson Plan Library## Pizza Anyone?## Susan Parsons## DescriptionStudents cooperatively create models of pizzas and divide them into the following fractions, 1/2, 1/3, 1/4.## ObjectivesThe student uses concrete materials to represent fractional parts of a whole (one half, one fourth).## Materials-Large white chart paper-Markers -Crayons -Scissors -Glue -Chalk -Chalkboard -Tape -Sentence strips -Construction paper-red, yellow, brown, green -Small baskets or containers to hold materials -Fabulous Fractions-lesson from Student Web Pages (optional) ## Preparations1.Cut 4 large circles from white chart paper.2.Collect markers, crayons, glue, construction paper and scissors in baskets or trays. 3.Draw several circles on the chalkboard, dividing them into equal and unequal parts. 4.Write Whole, ½, 1/3, and ¼ on sentence strips. 5.Divide the class into 4 groups that work well together. 6.Bookmark Fabulous Fractions Lesson from Student Web Pages. ## Procedures1.Have children name their favorite kinds of pizza.2.List their ideas on chart paper or the chalkboard. 3.Explain to the students that they will be making paper pizza with their classmates. 4. Divide children into 4 small groups. Give each group a large white paper circle. 5.Using the materials on the tables, the children will decorate a pizza. 6.While pizzas are drying, bring class together in front of chalkboard. 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. 13.Each group helps the teacher tape the pizza on the wall under the correct heading- whole, ½., 1/3, 1/4. 14. An optional follow-up activity is Fabulous Fractions, a Student Web Lesson, found on the Beacon Site. ## Assessments1.Observe that students work together and each child is contributing to the finished product. Observe that students use scissors, glue, and materials correctly and that they are shared in a cooperative manner. Offer feedback to those who need it.2.Assess the students’ knowledge of fractions during the group activity at the chalkboard. There is a checklist to record students' knowledge of fractions (concrete and identifying). ## Extensions1. Making real pizzas is a fun extension to this lesson.2. The Student Web Pages Lesson, Fabulous Fractions is a great follow-up activiy. ## Return to the Beacon Lesson Plan Library. |
