Deepening Students' Understanding of Multiplication and Division by Exploring Divisibility by Nine
Young-Loveridge, Jenny; Mills, Judith
Australian Mathematics Teacher, v68 n3 p15-20 2012
This article explores how a focus on understanding divisibility rules can be used to help deepen students' understanding of multiplication and division with whole numbers. It is based on research with seven Year 7-8 teachers who were observed teaching a group of students a rule for divisibility by nine. As part of the lesson, students were shown a way of proving why the divisibility rule for nine works, using materials grouped in tens and hundreds. After the lesson, students' understanding of multiplication and division was considerably deepened. (Contains 7 figures.)
