Preface ClassKlap partners with schools, supporting them with learning materials and processes that are all crafted to work together as an interconnected system to drive learning. ClassKlap presents the latest version of the Summit series – specially crafted as an accompanying workbook series for the Maharashtra state board textbooks. The Summit series endeavours to be faithful to the spirit of the National Curriculum Framework (NCF) 2005 in conjunction with the content covered and approach adopted in the Maharashtra state board textbooks. 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. Below are some salient features of the Summit Maths workbooks series:  Student engagement through simple, age-appropriate language  Word problems based on real-life scenarios, which help students to relate Mathematics to their everyday experiences  Appropriate space allotted to solve each question  All textbook questions that require space for writing have been included Overall, the ClassKlap Summit series aims to enhance logical reasoning and critical thinking skills that are at the heart of Mathematics teaching and learning. – The Authors NR_BGM_9789387848771-Summit-G3-Workbook-Maths-Part1_Text_New.pdf 2 3/21/2018 10:31:38 AM
