PREFACE The review of this Syllabus was necessitated by the need to improve the quality of education at High School Level as stipulated in the national policy document “Educating Our Future – 1996”. Quality education raises the standard of living for all. This leads to sustainable national development. The syllabus also addresses issues of national concern such as Environmental Education, Gender and Equity, Health Education and HIV/AIDS, Family Life Education, Human Rights, Democracy, Reproductive Health, Population Education, Entrepreneurship and Vocation Skills, Life and Values Education. Another reason for revising this syllabus was to fully localize the High School Examinations which were formerly set by University of Cambridge Local Examinations Syndicate, UK. It is hoped that this syllabus will provide the users with a sound premise on the basis of which meaningful and effective learning experiences will be developed in order to provide a good foundation for further study of this subject area.

The work to be covered in each of the Grades 10, 11 and 12 levels has been described separately. The aims and objectives of teaching Mathematics at Senior Secondary School level have been derived from three sources: The Educational Reform Document of 1997, the Structure of Mathematics as an academic discipline and the needs of the society. The syllabus is structured in such a way that the pupil is encouraged to put emphasis on the mathematical concepts, principles and creative thinking processes. When using this syllabus, it should be realised that Mathematics is a discipline with integrated and hierarchical concepts and skills. It is therefore, recommended that an integrated and spiral approach be used. iv GENERAL AIMS The general aims of teaching Mathematics at Senior Secondary level are to: 1. provide the pupil; with Mathematics background necessary for terminal and further education. 2. develop logical and substract thinking in the pupil. 3. enable the pupil to develop mathematical language and skills as a means of communication and investigation. 4. develop the ability of the pupil to use Mathematics as a tool in the Environment. 5. provide pupil with Mathematical skills to enable them to perform adequately in other subject areas. 6. enable the pupil to derive satisfaction and confidence from the understanding of mathematical concepts and masterly of mathematical skills. 7. stimulate and encourage creativity and a spirit of enquiry in the pupil. v TERMINAL OBJECTIVES At the end of Grade 12 pupils should be able to: 1. demonstrate spatial awareness in two and three dimension. 2. explore mathematical situations. 3. apply mathematical knowledge to problem-solving. 4. estimate, measure and calculate to an appropriate degree of accuracy using suitable methods. 5. recognise patterns and structures in a variety of situations form and justify generalisations. 6. represent, interpret and use data in a variety of situations. vi TIME AND PERIOD ALLOCATION This syllabus is a three-year course in mathematics and will require seven 40 minute periods per week. vii GRADE 10 TOPIC SPECIFIC OBJECTIVE BOYS AND GIRILS SHOULD BE ABLE TO: 1.
