11-12. Distance:
11-12.ACMEM083 use scales to find distances, such as on maps; for example, road maps, street maps, bushwalking maps, online maps and cadastral maps
11-12.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.
11-12. Speed:

11-12.ACMEM091 calculate perimeters of familiar shapes, including triangles, squares, rectangles, polygons, circles, arc lengths, and composites of these.
11-12.ACMEM092 review metric units of area, their abbreviations, and conversions between them
11-12.ACMEM093 use formulas to calculate areas of regular shapes, including triangles, squares, rectangles, parallelograms, trapeziums, circles and sectors
11-12.ACMEM106 interpret different forms of two-dimensional representations of three-dimensional objects, including nets and perspective diagrams
11-12.ACMEM107 use symbols and conventions for the representation of geometric information; for example, point, line, ray, angle, diagonal, edge, curve, face and vertex.
11-12. Interpret scale drawings:
11-12.ACMEM108 interpret commonly used symbols and abbreviations in scale drawings
11-12.ACMEM110 estimate and compare quantities, materials and costs using actual measurements from scale drawings; for example, using measurements for packaging, clothes, painting, bricklaying and landscaping.
11-12. Creating scale drawings:
11-12.ACMEM111 understand and apply drawing conventions of scale drawings, such as scales in ratio, clear indications of dimensions, and clear labelling
11-12.ACMEM124 interpret and use graphs in practical situations, including travel graphs and conversion graphs
11-12.ACMEM125 draw graphs from given data to represent practical situations
11-12.ACMEM126 interpret the point of intersection and other important features of given graphs of two linear functions drawn from practical contexts; for example, the 'break-even' point.
11-12.ACMEM130 investigate the different kinds of samples; for example, systematic samples, self-selected samples, simple random samples
11-12.ACMEM131 investigate the advantages and disadvantages of these kinds of samples; for example, comparing simple random samples with self-selected samples.
11-12.ACMEM132 identify the target population to be surveyed
11-12.ACMEM133 investigate questionnaire design principles; for example, simple language, unambiguous questions, consideration of number of choices, issues of privacy and ethics, and freedom from bias.
11-12.ACMEM136 investigate the possible misrepresentation of the results of a survey due to misunderstanding the procedure, or misunderstanding the reliability of generalising the survey findings to the entire population
