Students learn how to rationalise denominators of simple fractions.

Later, as learning progresses, they rationalise denominators using the complex conjugate.

**Differentiated Learning Objectives**

- All students should be able to rationalise a denominator with an integer term as the numerator.
- Most students should be able to rationalise a denominator with a surd as the numerator.
- Some students should be able to rationalise a denominator with an integer and surd in the numerator.
