Linear relationships, simultaneous equations and the shapes of common relationships, all used as modelling tools rather than as algebra for its own sake.
These are the statements the Mathematics Standard 2 syllabus makes about Strand: Algebra. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.
Gradient, intercept, and the equation of a line from two points or from a graph. Interpreting the gradient in context is usually worth more than computing it.
Linear, quadratic, exponential and inverse relationships recognised from a graph, a table or a description, and used to model real data.
Solving two equations in two unknowns by substitution, elimination or graphically, and interpreting the intersection as the solution to a real problem.
Recognising proportional relationships from the wording of a problem, writing the relationship as an equation, and using it to find an unknown.
HSC Mathematics Standard 2 - Trial Paper Shape is 100 marks in 150 minutes. Questions on Strand: Algebra are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Mathematics Standard 2 uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Strand: Algebra opens the Mathematics Standard 2 course. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Mathematics Standard 2 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
