Year 9

Quadratic expressions (9.9)

In this lesson, we will learn to recognise the difference between linear and nonlinear graphs.

Recognising linear and non-linear graphs

In this lesson, we will learn about the shape of a quadratic graph and begin plotting graphs of quadratic equations.

Plotting quadratics (Part 1)

In this lesson, we will identify the features of quadratic graphs. We will also practice plotting quadratic graphs.

Plotting quadratics (Part 2)

In this lesson, we will explore different situations that can be modelled by quadratics.

Quadratic contexts

In this lesson, we will explore how we can use quadratic graphs to solve maximum and minimum problems.

Maximum and minimum area

In this lesson, we will learn more about applying the distributive property of multiplication with variables. We will use area models to visualise the process.

Distributive property

In this lesson, we will learn more about expanding double brackets. We will use area models to visualise the process.

Expanding double brackets

In this lesson, we will learn about the difference of two squares. We will investigate the pattern of results when considering multiplying out brackets of the general form (x+a)(x-a).

Difference of two squares

In this lesson, we will learn how we can factorise quadratics using an array.

Factorising quadratics (Part 1)

In this lesson, we will further develop your ability to factorise quadratics by spotting factors of terms.

Factorising quadratics (Part 2)

In this lesson, we will learn how to sketch quadratics using intercepts of the y and x axis.

Sketching quadratics

In this lesson, we will explore different patterns related to quadratics and square numbers.
