Thisย workbook is designed for students of Class VII having aspiration of preparing for NTSE and IMO. Some of the basic content areas assigned in National Curriculum Framework are incorporated in this workbook.

This book cannot replace any textbook of the referred standard of National Curriculum. It will be an added content upon the prescribed ones for developing and strengthening the basic understanding of mathematical concepts that the fellow students want to aspire for. It will also confer the regular mathematical practice with which one should move for reducing any specific problems related to the understanding of mathematical concepts.

ย 

It is true that we cannot remember hundreds and thousands of different types of problems related to mathematics. We must try to equip ourselves differently for addressing all sorts of numerical and space related problems. Daily Practice Problem (DPP) series of publications deals with facilitation of fellow students and their associates. This workbook is suitable for students of class 3 of National Curriculum. It can be used by other fellow students of Primary section for improving their mathematical skills. It can be used by students who are willing to opt for IMO , NTSE and other similar examinations. It will also develop the basic understanding related to Mathematical Skills.

ย 

It will enhance the competency set up of those students and equip them differently so as to make them competent for addressing higher challenges. Focus is entirely made on the content areas which felt difficult for students under observation.
