More on rates and ratios
This module from the AMSI 'The Improving Mathematics Education in Schools (TIMES) project' is for teachers who wish to consolidate their content knowledge on the topic of rates and ratios and their uses. There are sections on the history, the context and exercises as well as examples on how to present and explain the concepts to students.

Use mathematical modelling to solve practical problems involving ratios; formulate problems, interpret and communicate solutions in terms of the situation, justifying choices made about the representation
Recognise and use rates to solve problems involving the comparison of 2 related quantities of different units of measure
Use mathematical modelling to solve applied problems involving growth and decay, including financial contexts; formulate problems, choosing to apply linear, quadratic or exponential models; interpret solutions in terms of the situation; evaluate and modify models as necessary and report assumptions, methods and findings
