Looking at proportional relationships
In this lesson, we will look at proportional relationships, in particular the unitary method whereby we calculate proportion as a ratio of 1:n.
Looking at proportional relationships
In this lesson, we will look at proportional relationships in familiar real world worded problem contexts.
Direct proportion (Part 1)
In this lesson, we will explore real life scenarios involving direct proportion and model solutions.
Direct proportion (Part 2)
In this lesson, we will learn how to recognise when two quantities are directly proportional to each other.
Direct proportion (Part 3)
In this lesson, we will solve worded problems involving direct proportion and model solutions using tables.
Graphs of proportional relationships
In this lesson, we will recognise and interpret the graphical representation of a proportional relationships.
The constant of proportionality
In this lesson, we will learn about the the term 'constant of proportionality' and how it relates to how proportion works.
Proportion in context
In this lesson, we will investigate word proportion problems involving exchange rates, and cost scaling. We will then model their solutions.
Inverse proportion
In this lesson, we will explore when two quantities are inversely proportional to each other. We will learn about the term inverse proportion and how to identify an inversely proportional relationship.
Inverse proportion in context
In this lesson, we will interpret, solve and model solutions to inverse proportion problems.
Graphs of inverse proportion problems
In this lesson, we will learn to recognise and distinguish the graphical representation of inverse proportion.
Direct or inverse proportion?
In this lesson, we will solve a variety of direct and inverse proportion problems. We will learn how to identify when a problem is about direct or inverse proportion.
