- Batch of 8
- Free demo every Saturday
Four things parents notice within a year
The abacus itself is only the first year. After that the child pictures it in the head and moves the beads with the mind. That is the real skill.
Concentration
A child doing ten-row sums in the head cannot think about anything else. Teachers tell us the same child sits still in school too.
Speed with accuracy
By Level 4 most children add fifteen two-digit numbers in under thirty seconds without paper, and get it right. School maths stops being a fear.
Memory and listening
Dictation sums train the child to hold numbers in the head while listening. Spelling and tables improve as a side effect.
Confidence
Every level ends with a certificate. Every year there is a competition hall. Finishing a paper on a stage at seven is something a child keeps.
What your child can do at the end of each level
Each level takes three to four months. There is a written and a speed test at the end, with a certificate from our affiliating body. The full course takes about two and a half years.

Twenty sums at the child's own pace. The teacher walks the room and corrects fingers, not just answers.
- 35-42 minMental round
Abacus goes into the bag. Dictation sums, eyes closed, answers written down.

Our children, in and out of class
Two honest notes from parents
My daughter counted on her fingers in Class 2. A year later her class teacher asked me what had changed. Now she does the shop bill before the shopkeeper does.
At the demo they told us our son was too young and to come back in six months. We did. That honesty is why we have stayed four years.
Questions we are asked at every demo
What is the right age to start?
Five to seven is ideal. The child should know numbers 1 to 100 and be able to sit for 45 minutes. We take children up to 14; older children join a separate batch and move faster.
Will it clash with school maths?
No. Abacus gives the answer; school teaches the method. Children write school sums the school's way and use the mental picture to check. Teachers usually notice only that the child is faster.
How much practice at home?
Ten minutes a day from the practice book. Not more. Parents do not need to know abacus to help; the book has answers at the back.
What if my child misses a class?
Tell us and the child sits in another batch the same week. If a whole month is missed for illness or travel, we pause the fee for that month.
Is the certificate recognised?
Level certificates come from our affiliating abacus association and are accepted at state and national competitions. They are not a school-board qualification and we do not claim they are.
Can we try before paying?
Yes. The Saturday demo class is free and parents sit in. If the child enjoys it, you join from the next week. If we think the child is too young, we say so and ask you to come back later.
