ClassKlap presents the Compass 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).

Each of these principles resonates with the spirit in which the ClassKlap textbooks, workbooks and teacher companion books have been designed. The ClassKlap team of pedagogy experts has carried out an intensive mapping exercise to create a framework based on the CISCE curriculum document. Key features of ClassKlap Compass 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.  L earning 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.
