The Quality Mathematics series for school students is developed to promote meaningful and enjoyable learning resources in school mathematics. This series is developed according as the existing school curriculum of Nepal. While developing this series we incorporated the global practices as well as local needs and interests of the students. This series is developed considering our experiences in the development of mathematics curriculum, learning materials, training materials and textbook, and in teaching and conducting teachers’ training. The results from the experiments conducted during the process of writing this book have also been considered while developing this book. The Quality Mathematics Book 4, one of the books of the series, has been designed for grade one students of Nepal following strictly the curriculum developed by the Curriculum Development Centre, Government of Nepal.
