The first module of the number and algebra course dealt with linear patterns including arithmetic sequences and linear functions. The concepts of starting value and rate of change were discussed including methods for identifying each from tables, graphs and formulae.

Module 1 Presentation Module 1 Activities

The second module of the number and algebra course dealt with the idea that not all real-life situations can be accurately modeled using a linear pattern. This lead to the introduction of quadratic, cubic and exponential patterns and an investigation of the main features / properties of each function type.

Module 3 of the number and algebra course focused on investigating more complicated quadratic and exponential patterns. As part of this process geometric sequences were introduced and their general properties discussed. Time was also given to investigation arithmetic-geometric sequences.

Module 3 presentation Module 3 activities (includes module 4 activities)

The final module of the number and algebra course focused on geometric sequences and exponential functions in the context of finance. Time was spent using knowledge of geometric sequences to solve problems involving compound interest, reducing balance, annual equivalent interest rates and amortisations.

Module 4 presentation Module 4 activities (includes module 3 activities)
