Keys: Unlocking Maths G12 - Used in Government and IEB Schools across South Africa.This is a single book covering the year's syllabus. The material is designed so the content builds on the concepts and skills acquired as the learner progresses. Each topic is addressed with an explanation, examples and rules that are highlighted in a box. This is followed by graded questions designed to build knowledge and skills by consolidating the concepts being covered. Space is provided for answers for some of the given tasks but where workings need to be shown, work should be done in a classwork book. There are resource pages at the back of the book with perforations that can be torn out to work on. A revision test with Memorandum is provided at the end of each section to encourage thorough preparation for an assessment of the work covered.
