Convert between standard decimal notation and scientific notation.

Order a set of real numbers.

Generalise that corresponding sides of similar shapes are proportional.

Compare the attributes of a shape and its dilation on a coordinate plane.

Explain the effect of a scale factor applied to a figure about the origin.

Use similar right triangles to show slope is the same for any two points on a line.

Graph proportional relationships and read the unit rate as the slope.

Determine the rate of change and y-intercept from a table or graph.

Represent linear proportional situations as y = kx.

Represent linear non-proportional situations as y = mx + b.

Contrast bivariate data that suggests a linear relationship with data that does not.

Use a trend line to make predictions from bivariate data.

Solve problems involving direct variation.

Distinguish proportional from non-proportional situations.

Identify functions from ordered pairs, tables, mappings and graphs.

Identify examples of proportional and non-proportional functions.

Write y = mx + b from a verbal, numerical, tabular or graphical description.

Describe the volume formula V = Bh of a cylinder.

Model the relationship between the volume of a cylinder and a cone.

Use models and diagrams to explain the Pythagorean theorem.

Partial Applies the theorem to find a side. Does not ask for the model that explains it.

Solve problems involving the volume of cylinders, cones and spheres.

Determine lateral and total surface area of prisms and cylinders.

Establish the triangle angle sum, exterior angle and angle-angle similarity.

Generalise the orientation and congruence properties of transformations.

Differentiate transformations that preserve congruence from those that do not.

Explain the effect of translations, reflections and rotations algebraically.

Model the effect of a dilation on linear and area measurements.
