Factors of an Integer

The start of the lesson involves organising integers within a Venn diagram according to their number properties.   Students build on this in the development phase by considering the factors of an integer using a times table grid and then mental methods.   The application of calculating factors extends their learning later in the lesson by derivation of Primes and Square Numbers.
Differentiated Learning Objectives
• All students should be able to calculate the factors of an integer using a times table grid.
• Most students should be able to calculate the factors of an integer using mental methods.
• Some students should be able to discover the first ten prime and square numbers by considering their factors.
