Introduction to Mathematical Literacy

What is Mathematical Literacy all about?

According to the Curriculum and Assessment Policy Statement (CAPS) for Mathematical Literacy:

The competencies developed through Mathematical Literacy allow individuals to make sense of, participate in and contribute to the twentyfirst-century world -- a world characterised by numbers, numerically based arguments and data represented and misrepresented in a number of different ways.

Such competencies include the ability to reason, make decisions, solve problems, manage resources, interpret information, schedule events and use and apply technology.

Learners must be exposed to both mathematical content and real-life contexts to develop these competencies.

Mathematical content is needed to make sense of real-life contexts; on the other hand, contexts determine the content that is needed.

It is clear that, in Mathematical Literacy, both mathematical content and real-life contexts are crucial. Mathematical content provides us with a means for accessing and making sense of real-life contexts, while real-life contexts provide meaning for the content and a reason for learning the content.

Equally important to content and context, however, is that learners must develop problem-solving skills. This involves the ability to apply mathematical content in order to solve problems based on often complex and unfamiliar real-life contexts. The focus in Mathematical Literacy is on the use of content rather than on the knowing of content.

How this guide will help you

This Via Afrika Study Guide will help you prepare for your Grade 10 end-of-year examination. The authors carefully thought of what a learner requires to effectively prepare for and successfully write the examination. They identified these needs: an understanding of the basic mathematical content that will be assessed in the

end-of-year examination an understanding of the nature and purpose of Mathematical Literacy, and how it

will be assessed an example of Paper 1 and Paper 2 with complete solutions, accompanied by

comments to help you understand how to answer each question.

To meet these needs, this Study Guide has been divided into the following topics:

Topics 1 and 2 ? Basic and Application Mathematical Skills

These contain summaries of the mathematical content and skills that you should learn.

The topics have been divided into chapters, each dealing with a different concept. It follows this pattern: revision of the concepts outlined in the curriculum for Grade 10 examples based on the concepts covered practice exercises that give you opportunities to practise what you have learnt.

Work through the topics thoroughly to enable you to apply the necessary concepts and skills when you work through the exam papers.

Exam question papers

This section contains information about: how exam question papers are drawn up how Paper 1 is different to Paper 2 the four levels on which you will be assessed how to approach answering questions in any exam (or test) paper.

In addition, this section contains: examples of Paper 1 and Paper 2 memoranda (solutions) to the two papers comments in the memoranda to help you understand and answer each question.

These comments refer to the level of the question, the purpose of the question, and the content or skills required to answer the question.
