Wiskunde Studiegids - Graad 9

This learner-friendly book is an invaluable tool in understanding Grade 9 Mathematics.

∙It explains the basic concepts of Grade 9 Maths and more complicated questions (such as exam-type questions) in a way that learners can easily understand. It uses colour coding, highlighting important information and useful notes, and simple, easy-to-understand language.

∙In Grade 9, learners are introduced to new concepts such as factorisation, quadratic equations, and straight-line graphs, which are all extremely important in Grades 10-12. Although learners could initially find such new concepts somewhat daunting, the Grade 9 Maths 4 Africa study guide explains everything step by step in a way they will find easy to understand.

∙In the chapter on factorisation, for example, a summary of the different types of factorisation is given first, followed by a step-by-step explanation of each. Various work examples are then provided, and learners can practise mixed factorisation and handle more complicated questions.

∙Quadratic equations are also new to Grade 9. The Grade 9 Maths 4 Africa study guide explains this concept, helping learners understand different equations.

∙Straight-line graphs form the basis of all other graphs studied in Grades 10-12. This chapter is, therefore, extremely important. The Grade 9 Maths 4 Africa study guide keeps explanations simple, using easy-to-understand language and colour coding to explain the concept of gradients, different types of lines, etc. All aspects of straight-line graphs, including drawing straight-line graphs, finding the equations of straight lines and interpreting such graphs, are covered in this chapter.

∙In the chapter on probability, tree diagrams are explained simply, thereby preventing learners from becoming confused by different scenarios.

∙Even though everything is explained simply and clearly, this study guide also includes more difficult exam-type questions, thereby helping learners prepare for tests and exams.

∙Learners who regularly use the Grade 9 Maths 4 Africa study guide will find this book invaluable. It has been designed to help learners succeed.
