PREFACE The use of technology in the teaching and learning of Additional Mathematics is greatly emphasised. Additional Mathematics taught inScience and technology plays a critical role in realising Malaysia’s English, coupled with the use of ICT, provide greater opportunities foraspiration to become a developed nation. Since mathematics is instrumental pupils to improve their knowledge and skills in mathematics because of thein the development of scientific and technological knowledge, the provision richness of resources and repositories of knowledge in English. Our pupilsof quality mathematics education from an early age in the education process will be able to interact with pupils from other countries, improve theiris thus important. The Malaysian school curriculum offers three proficiency in English; and thus make the learning of mathematics moremathematics education programs, namely Mathematics for primary schools, interesting and exciting.Mathematics and Additional Mathematics for secondary schools. The development of this Additional Mathematics Curriculum SpecificationsThe Malaysian school mathematics curriculum aims to develop is the work of many individuals and experts in the field. On behalf of themathematical knowledge, competency and inculcate positive attitudes Curriculum Development Centre, I would like to express much gratitude andtowards mathematics among pupils. While the Mathematics curriculum appreciation to those who have contributed in one way or another towardsprepares pupils to cope with daily life challenges, the Additional this initiative.Mathematics curriculum provides an exposure to the level of mathematicsappropriate for science and technology related careers. As with othersubjects in the secondary school curriculum, Additional Mathematics aimsto inculcate noble values and love for the nation in the development of aholistic person, who in turn will be able to contribute to the harmony andprosperity of the nation and its people.Additional Mathematics is an elective subject offered to the upper (MAHZAN BIN BAKAR SMP, AMP)secondary school pupils. Beginning 2003, English is used as the medium of Directorinstruction for Science and Mathematics subjects. The policy to change the Curriculum Development Centremedium of instruction for the two subjects follows a phased implementation Ministry of Educationschedule and is expected to be completed by 2008. The teaching and Malaysialearning of Additional Mathematics in English started in 2006. (vii)

INTRODUCTION are also stressed in the process of learning Additional Mathematics. WhenA well-informed and knowledgeable society, well versed in the use of pupils explain concepts and their work, they are guided in the use of correctMathematics to cope with daily life challenges is integral to realising the and precise mathematical terms and sentences. Emphasis on Mathematicalnation’s aspiration to become an industrialised nation. Thus, efforts are taken communications develops pupils’ ability in interpreting matters intoto ensure a society that assimilates mathematics into their daily lives. Pupils mathematical modellings or vice versa.are nurtured from an early age with the skills to solve problems andcommunicate mathematically, to enable them to make effective decisions. The use of technology especially, Information and Communication Technology (ICT) is much encouraged in the teaching and learning process.Mathematics is essential in preparing a workforce capable of meeting the Pupils’ understanding of concepts can be enhanced as visual stimuli aredemands of a progressive nation. As such, this field assumes its role as the provided and complex calculations are made easier with the use ofdriving force behind various developments in science and technology.

The tasks given must therefore be based on chapters that havealready been learnt and pupils are expected to complete it within the durationof three weeks. Project work can be done in groups or individually but eachpupil is expected to submit an individually written report which include thefollowing: • title/topic; • background or introduction; • method/strategy/procedure; • finding; • discussion/solution; and • conclusion/generalisation.
