4th grade or 7th grade

Peter has three thanksgiving pies. He wants to cut the first pie into 8 pieces, the second pie into 9 pieces, and the third pie into 15 pieces. Draw a picture to how Peter should cut the pies.

Note: For 4th grade the pies pieces can be estimated (make sure that the concept of factoring is uesd). For 7th graders a protractor should be used and the drawings should be perfect.
