A Fruitful Activity for Finding the Greatest Common Factor
Bell, Carol J.; Leisner, Heather J.; Shelley, Kristina
Mathematics Teaching in the Middle School, v17 n4 p222-229 Nov 2011
Posing mathematics problems in different ways will raise students' level of cognitive demand because it will push them to think more deeply about mathematics. By engaging students in a task that requires them to determine their own solution strategies, students will gain a deeper understanding of the mathematical concept explored through the task. This article discusses an activity that led seventh-grade students to develop an understanding of the concept of greatest common factor (GCF) through their solutions to different situations posed in a problem. The goal of the activity was for students to explore the concept of greatest common factor before the term was introduced. When developing the activity, smaller numbers were chosen for the questions so that manipulatives could easily be used. An activity sheet on the fruit basket challenge is presented. (Contains 5 figures.)
