This course introduces students to the four core abacus drills that reinforce the technical foundation established in the "Abacus for Beginners" course. These drills function much like daily technique practice for musicians. Just as pianists develop finger strength, speed, and independence through scales and arpeggios, consistent drill practice builds precision, rhythm, and fluency on the abacus.
Students are encouraged to work on one or all drills before working on their workbook assignments each time. Regular practice significantly accelerates progress by strengthening bead control, reinforcing number patterns, and improving calculation flow.
The four drills emphasize structured repetition and pattern recognition:
1. Drill 1: Add 1.23456789 for 10 times. It trains controlled addition through repeated sequences while introducing decimal numbers.
2. Drill 2: Subtract 1.23456789 from 12.3456789 to 0. It develops subtraction accuracy and stability through reverse sequencing, also incorporating decimal numbers.
3. Drill 3: Adding: 1+2+3+$+5+6+7+8+ ... + 97+98+99+100. It builds forward accumulation and endurance in continuous addition.
4. Drill 4: Subtracting: 5050-1-2-3-4-5-6-7-8- ... -97-98-99-100. It strengthens backward tracking and consistency in extended subtraction chains.
Together, these drills form the technical backbone needed for faster execution and a smoother transition into advanced mental calculation. Mastery of the drills prepares students to move beyond the beginner stage with confidence and efficiency.
The followings are highly recommended for students to take care of at the same time (not included in this subscription) in order to achieve the best result:
5. Abacus Multiplication for multiplying a 1-digit number. The workbooks are multiplication/division Levels 9 and 8.
6. Mental Multiplication for multiplying a 1-digit number. This includes multiplication/division levels 10, 9, 8, 7, 6, and 5 on the mobile app, MM Go.
7. Find the missing factors in a 1-digit times 1-digit question. The workbook is multiplication/division Levels 9.
8. Division without a remainder in the Times Tables range. The workbook is multiplication/division Levels 9.
9. Division with a remainder in the Times Tables range. The workbook is multiplication/division Levels 9.
10. Abacus division by a 1-digit number. The workbooks are multiplication/division Levels 9, 8, and 7.
