# Mathematics Performance band descriptions

The draft performance bands shown on the following page represent student performance in bands of achievement. They illustrate the typical performance of students in the Mathematics HSC course.

Each band contains descriptions of student achievement of the course outcomes.  The bands will continue to be refined to include information from performance in the new HSC courses and the outcomes assessed internally.

The typical performance in this band:

## Band 6

• Uses sophisticated multi-step reasoning
• Integrates ideas of calculus with strong algebraic, deductive and modelling skills to successfully solve difficult problems
• Exhibits excellent problem solving skills
• Communicates effectively using appropriate mathematical language, notation, diagrams and graphs

## Band 5

• Exhibits sound knowledge and skills appropriate to the Mathematics course
• Uses multi-step logical reasoning in both numerical and theoretical contexts such as problems in calculus, geometry and probability
• Combines ideas of calculus with algebraic, deductive and modelling skills to successfully solve many difficult problems
• Exhibits a wide range of problem solving skills such as applications of series
• Communicates effectively using mathematical language, notation, diagrams, and graphs

## Band 4
