Preface IMAX partners with schools, supporting them with learning materials and processes that are all crafted to work together as an interconnected system to drive learning. Our books also strive to ensure inclusiveness in terms of gender and diversity in representation, catering to the heterogeneous Indian classroom. IMAX presents the Traveller series, designed specifically to meet the requirements of the new curriculum released in November 2016 by the Council for the Indian School Certificate Examinations (CISCE). Guiding principles: The 2016 CISCE curriculum states the following as a few of its guiding principles for Mathematics teaching: Develop mathematical thinking and problem-solving skills and apply these skills to formulate and solve problems. Acquire the necessary mathematical concepts and skills for everyday life and for continuous learning in Mathematics and related disciplines. Recognise and use connections among mathematical ideas and between Mathematics and other disciplines. Reason logically, communicate mathematically and learn cooperatively and independently. Each of these principles resonates with the spirit in which the IMAX textbooks, workbooks and teacher companion books have been designed. The IMAX team of pedagogy experts has carried out an intensive mapping exercise to create a framework based on the CISCE curriculum document. Key features of IMAX Traveller series: Theme-based content that holistically addresses all the learning outcomes specified by the CISCE curriculum. The textbooks and workbooks are structured as per Bloom’s taxonomy to help organise the learning process according to the different levels involved. Student engagement through simple, age-appropriate content with detailed explanation of steps. Learning is supported through visually appealing images, especially for Grades 1 and 2. Increasing difficulty level in sub-questions for every question. Multiplication tables provided as per CISCE requirement. All in all, the Traveller Mathematics books aim to develop problem-solving and reasoning skills in the learners’ everyday lives while becoming adept at mathematical skills as appropriate to the primary level. – The Authors NR_BGM_9789387552173-TRAVELLER-G03-MATHS-WORKBOOK-PART2_Text.pdf___2 / 64
