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. IMAX presents the latest version of the Alpine series – updated and revised after considering the perceptive feedback and comments shared by our experienced reviewers and users. Designed specifically for state board schools, the Alpine series endeavours to be faithful to the spirit of State Curriculum Framework and the National Curriculum Framework (NCF) 2005. Therefore, our books strive to ensure inclusiveness in terms of gender and diversity in representation, catering to the heterogeneous Indian classroom. The aim of the NCF 2005 regarding Mathematics teaching is to develop the abilities of a student to think and reason mathematically, pursue assumptions to their logical conclusion and handle abstraction. The Alpine Mathematics textbooks and workbooks for state board schools offer the following features:  Structured as per Bloom’s taxonomy to help organise the learning process according to the different levels involved  Student engagement through simple, age-appropriate language  Supported learning through visually appealing images, especially for grades 1 and 2  Increasing rigour in sub-questions for every question in order to scaffold learning for students  Word problems based on real-life scenarios, which help students to relate Mathematics to their everyday experiences  Mental Maths to inculcate level-appropriate mental calculation skills  S tepwise breakdown of solutions to provide an easier premise for learning of problem-solving skills Overall, the IMAX Alpine Mathematics textbooks, workbooks and teacher companion books aim to enhance logical reasoning and critical thinking skills that are at the heart of Mathematics teaching and learning.  – The Authors NR_BGM_181010005-Alpine-G1-Workbook-Maths-Part1_Text.pdf 2 1/25/2018 10:15:40 AM
