Abacus Series – Level 1 Of 8 is a unique book designed and published by Nava Vision for children aged 3 years and above, to encourage them to attain better usage of abacus to solve various problems. Compiling this book with valuable and unique content, and binding it up expertly has been a group effort of our Nava Vision Team. This unique book promotes brain growth, creativity and personality development in young children. The book starts with the basics of counting numbers and proceeds to abacus representations. We have provided many learning sessions for the students to practice and learn various concepts. The book also concentrates on mental abacus, which is very crucial, as it improves imagination and students need to be independent of the abacus kit once they are well-versed with the arrangement of beads. This book will inculcate the best practice of using mental abacus in the early stages of a child’s life.
