## Subject knowledge for teachers and educators without a maths background

Proportional reasoning and the use of ratios is required across different areas of the mathematics curriculum. It is essential to many areas of science and technology and is used in a range of situations in both life and work.

In this course we will explore different mathematical strategies to enable you to solve proportional reasoning problems. By participating in this course you will discover multiplicative reasoning strategies, links between ratio and proportion and the ability to scale things up and to scale things down.

## What topics will you cover?

• What is proportional (multiplicative) reasoning
• Scaling up and scaling down using the unitary method
• The definition and application of ratios
• How to use proportion reasoning when dealing with areas and volumes
• Proportional reasoning and ratio in applied science and technology contexts

## Who is this accredited by?
