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 Program presents the latest version of the Magnolia series – updated and revised after considering the perceptive feedback and comments shared by our experienced reviewers and users. The Magnolia series endeavours to be faithful to the spirit of the prescribed board curriculum. Our books strive to ensure inclusiveness in terms of gender and diversity in representation, catering to the heterogeneous Indian classroom. The larger aim of the curriculum 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 Magnolia Mathematics textbooks and workbooks offer the following features:  S tructured as per Bloom’s taxonomy to help organise the learning process according to the different levels involved  S tudent engagement through simple, age-appropriate language  S upported 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  W ord 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 Supplemental practice questions included at the end of each chapter, for revision and exam preparation Overall, the IMAX Magnolia 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
