Instructions ● You can visit our YouTube channel & watch this playlist “Best Abacus playlist available
online” to learn the basic concepts of Addition & Subtraction. After you watch a video, you can solve the respective questions in this book.
● Do not watch all the videos first & start solving this book from the first page. Instead, follow this approach,
○ Watch a video → Solve that topic’s questions in this book → Move to the next video → Repeat.
● Solve each row separately, start the stopwatch & mention Time in the Time Taken box.
● If you are interested to share with us how much time you are taking to solve each row, or, if you want to get feedback, or if you have any questions, you can always reach out to us on WhatsApp at +91-8179328370 ● On top of each table, Abacus (or) Visualization is mentioned. So, practice that way. ● For extra practice (or) if you want to practice online, you can visit the website https://practiceabacusonline.com/
● Important Note:
○ Don't just solve the assignments, but also, apply Abacus methods in your school. Also, try to solve real-world calculations using Abacus/Visualization.
○ In this way, you will automatically practice the Abacus, improve your speed & you will remember the concepts for long. This is the right way to practice Abacus & I myself have followed these points to improve my speed and to remember the concepts. ● Skills → It is same as multiplication table. Example, for 11 to 99, you have to add 11 each and every time upto 99 i.e 11, 22, 33, 44, 55, 66, 77, 88, 99 along with the stopwatch & mention the time taken in the table. ● Speed Writing → Write 0 to 9 in the speed writing table using right hand for the first time & using left hand for the second time.

Frequently Asked Questions 1. How much time to practice daily?
a. Practice makes you a master at Abacus. The more you practice, the faster you become. 10 minutes of daily practice is better than 60 minutes of practice in a single day. So, we highly recommend practicing for at least 10 minutes once in 2 days. Every time it will not be possible to practice daily, so in that case, you can practice alternate days/once in 3 days. Or, if you can practice daily for 10 minutes, that would be great. 2. How to improve speed? a. Practice frequently. b. Fast finger movements. c. Track your speed periodically. d. Follow the speed tips. 3. How is Abacus useful? a. Abacus is useful to solve calculations quickly. It is helpful in improving your concentration, focus, memory power, listening skills, writing skills, visualization power, and gaining more interest in Math. 4. How to remember Abacus concepts for long?
a. Don't just solve the assignments, but also, apply Abacus methods in your school. Also, try to solve real-world calculations using Abacus/Visualization. In that way, you will automatically practice the Abacus & you will remember the concepts for a long time. 5. Where to buy the Abacus tool? a. You can buy an Abacus Tool on Amazon or any local store in your country. It is easily available. I highly recommend you to buy a 13-rod Abacus rather than a 15 or 17-rod Abacus. The reason is, 13-rod Abacus is easy to hold & it is very comfortable. 6. How parents should assess their kids? a. Parents should periodically check their kids by making them practice assignments & dictations or any real-world calculations & ask them to use Abacus to solve them. Parents should make their kids practice frequently & also check whether they are using the Abacus method/school method/using a calculator while completing the assignments. b. Parents should encourage their kids to participate in Abacus Competitions held by various institutions.

Participating in various Abacus Competitions is very important because Competitions are challenging, students get exposure to other students from different places, the environment is very competitive. Students get motivated by seeing other students, and on top of all these, students want to win. They will develop the spirit to win. 10. How fast you can solve using Abacus? a.
