# WACE Mathematics Essential General – Unit 3

3.1 Measurement

3.2 Scales, plans and models

3.3 Graphs in practical situations

3.4 Data collection

This unit provides students with the mathematical skills and understanding to solve problems related to measurement, scales, plans and models, drawing and interpreting graphs and data collection. Students use the mathematical thinking process and apply the statistical investigation process. Teachers are encouraged to apply the content of the four topics in this unit: Measurement, Scales, plans and models; Graphs in practical situations; and Data collection in a meaningful context and of interest to the students. A variety of approaches could be used to achieve this purpose. Possible contexts for this unit are Construction and design, and Medicine.

It is assumed that an extensive range of technological applications and techniques will be used in teaching this unit. The ability to choose when and when not to use some technology and work flexibly with technology are important skills.

The number formats for the unit are positive and negative numbers, decimals, fractions, percentages, rates, ratios, and square and cubic numbers written with powers and square roots.
