## Unit description of WACE Maths Applications Unit 1 Year 11 ATAR Course

WACE Maths Applications Unit 1 Year 11 ATAR Course has three topics:

- Consumer arithmetic,
- Algebra and matrices, and
- Shape and measurement.

**Consumer arithmetic** reviews the concepts of rate and percentage change in the context of earning and managing money and provides a fertile ground for the use of spread sheets.

**Algebra and matrices** continues the Year 7–10 curriculum study of algebra and introduces the topic of matrices. The emphasis of this topic is the symbolic representation and manipulation of information from real-life contexts using algebra and matrices.

**Shape and measurement** builds on and extends the knowledge and skills students developed in the Year 7–10 curriculum with the concept of similarity and associated calculations involving simple geometric shapes. The emphasis in this topic is on applying these skills in a range of practical contexts, including those involving three-dimensional shapes. Classroom access to the technology necessary to support the computational aspects of the topics in this unit is assumed.
