Expressions, equations and inequalities

In this lesson, we will be introduced to algebraic notation and learn how to evaluate and substitute into expressions.

In this lesson, we will learn to collect together terms that are alike and manipulate linear expressions.

In this lesson, we will use the distributive property to expand brackets with linear expressions.

In this lesson, we will learn how to factorise basic linear expressions using area models.

In this lesson, we will learn the concept of an equation and use models to form equations.

In this lesson, we will form equations and explore how to ensure equality is preserved.

In this lesson, we will use bar modelling to identify and form inequalities.

In this lesson, we will learn how to form inequalities related to a known equation.

In this lesson, we will learn how to form expressions using algebraic lengths and draw shapes given expressions for the perimeter.

In this lesson, we will learn how to establish inequalities from perimeter expressions.

In this lesson, we will generalise counting strategies algebraically for repeating patterns.

In this lesson, we will learn how to generalise counting strategies algebraically for different repeating patterns.
