Mathematics Topical Guide is a series of four books specially written for students taking the O Level Mathematics Syllabus 4048. It is essential for students to acquire and apply mathematical concepts and skills for progressive learning to support learning in other subjects as well. In this series, the topics are classified into individual lessons to cater to the learning needs of the students at the respective level. A handy and comprehensive guide to complement the learning of mathematical concepts, each topic comprises the following features: - Concise Summary Notes are used to highlight important procedures, concepts, rules and formulae to aid learning. - Detailed Worked Examples in each lesson are included to show the application of the mathematical concepts and formulae learnt. - An array of Practice Questions in each lesson is given to provide opportunities to practise and apply the mathematical concepts and skills for progressive learning. - To consolidate and extend students’ learning, at the end of each topic, the questions in the Review Corner are arranged into three levels of difficulty. Beginner, Intermediate and Advanced Level. - Appropriate Teacher’s Comments, Notes and Tips are incorporated as timely reminders of important pointers and to provide a more concise explanation of worked solutions. - To conclude a topic, the Checklist for My Learning Outcomes is presented to help students examine the progress of their learning and understanding of that topic. - Detailed Worked Solutions to every question are provided as a useful resource tool for students to make reference to their own solutions. - Relevant Problems in Real-World Contexts are included to enable students to connect and apply the concepts that they have learnt, to real-world situations. - Two sets of End-of-Year Examination Specimen Papers are crafted to assess student’s readiness for the school examination.
