你将学到什么

Identify problems that can be solved using proportional reasoning.

Solve problems of scaling up and scaling down using the unitary method.

Solve problems of ratio with two and three quantities.

Apply proportional reasoning to conversion and compound measure problems.

Apply proportional reasoning to scaling of area and volume.

课程概况

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.
