Positive and negative numbers

In this lesson, we will interpret negative numbers in a variety of contexts and explore movement on an 'extended' number line.

Negative numbers in context

In this lesson, we will learn to interpret the absolute value of a number and understand how to order negative numbers using inequality notation.

Order and absolute value

In this lesson, we will be able to model addition of a positive number as a translation on the number line and use this model to develop strategies for addition.

Modelling Addition

In this lesson, we will learn how to model addition of a negative number as a translation on the number line and explore what happens when two additive inverses are added together.

Further Addition

In this lesson, we will explore the relationship between subtracting positive numbers and adding additive inverses.

Subtracting positive numbers

In this lesson, we will explore subtracting negative numbers as the addition of the additive inverse.

Subtracting negative Numbers

In this lesson, we will explore multiplication involving at least one positive number and learn how it is possible to visualise multiplication as a stretch by a scale factor.

Multiplication as scaling

In this lesson, we will learn about negative scale factors and explore the commutativity of multiplication.

Negative scale factors

In this lesson, we will investigate how to find the product of two negative numbers.


Further multiplication

In this lesson, we will explore a model for division involving counting backwards and analysing a number line.

Division

In this lesson, we will derive further division facts using 'fact families'.

Further division

In this lesson, we will practise negative number calculations, linking them to axioms like commutativity and associativity.
