display numerical data as frequency distributions, dot plots, stem and leaf plots, and histograms

ACMEM070

use ratio to describe simple scales.

ACMEM076

use units of time, conversions between units, fractional, digital and decimal representations

ACMEM080

use rates to determine costs; for example, calculating the cost of a tradesman using rates per hour, call-out fees.

ACMEM083

use scales to find distances, such as on maps; for example, road maps, street maps, bushwalking maps, online maps and cadastral maps

ACMEM054

use informal ways of describing spread, such as spread out/dispersed, tightly packed, clusters, gaps, more/less dense regions, outliers

ACMEM084

optimise distances through trial-and-error and systematic methods; for example, shortest path, routes to visit all towns, and routes to use all roads.
