Students learn how to find all the factor pairs of numbers and terms. More able are taught to find the factors of algebraic expressions. Less able students are supported with a timetables grid.
The start of the lesson is used to review finding the lowest common multiple of two numbers using Venn diagrams. In the main part of the lesson students use factor pairs to find all the factors of numbers and simple expressions. At the end of the lesson students are challenged to find the factors of larger numbers by chunking.
Differentiated Learning Objectives
- All students should be able to use factor pairs to calculate all the factors of an integer.
- Most students should be able to use factor pairs to calculate factors of an integer and term.
- Some students should be able to explore the factors of an algebraic expression.
