Plotting quadratics (Part 1)
In this lesson, we will learn about the shape of a quadratic graph and begin plotting graphs of quadratic equations.
Plotting quadratics (Part 2)
In this lesson, we will identify the features of quadratic graphs. We will also practice plotting quadratic graphs.
Quadratic contexts
In this lesson, we will explore different situations that can be modelled by quadratics.
Maximum and minimum area
In this lesson, we will explore how we can use quadratic graphs to solve maximum and minimum problems.
Distributive property
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.
Expanding double brackets
In this lesson, we will learn more about expanding double brackets. We will use area models to visualise the process.
Difference of two squares
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).
Factorising quadratics (Part 1)
In this lesson, we will learn how we can factorise quadratics using an array.
Factorising quadratics (Part 2)
In this lesson, we will further develop your ability to factorise quadratics by spotting factors of terms.
Sketching quadratics
In this lesson, we will learn how to sketch quadratics using intercepts of the y and x axis.
Interesting quadratic patterns
In this lesson, we will explore different patterns related to quadratics and square numbers.
