"The abacus helps children to hold large, exact numbers and to compute arithmetic calculations in a rapid and precise way."
What is an Abacus?
The abacus (a tool primarily used to do calculation in East Asia) largely influences the way how numbers are represented in children’s thinking.
The abacus is a counting board that uses a representation with place values mapped to individual columns. The abacus displays numbers exactly like arabic numerals in a system.
What is Mental Arithmetic?
The abacus training’s ultimate aim is to enhance the child’s ability to do calculation without the aid of any physical instrument such as pen, paper, abacus, and calculator. Children will be able to hold mental images and motor operations to calculate by using their own mental power.
“I don’t want my child be baffled by math when they are young.”
â€‹
You may be warned that sending your kid to learn math too soon is counterproductive. When they struggle, they begin to dread math.
This program will overthrow your stereotype about math learning.
We are not pushing our students to grasp math at higher levels before they are ready. Instead, our abacus program ground them in the basics. Some kids do start struggling from simple addition and subtraction. The abacus and mental arithmetic is an approach to train children tackle arithmetic problems using a base10 system instead of verbal counting.
â€‹
With a solid foundation in arithmetic, they will be more prepared to learn algebra and geometry. Most importantly, they won’t be intimidated by numbers. They can truly enjoy the challenges in math and play around it. Eventually, we won’t lose thousands of students who could be the scientists and engineers of tomorrow.
When is the best age to learn?
Age 4. When children have good control of their motor skills and able to write numbers.
What are the benefits?
â€‹

Calculate with great speed and accuracy

Improve concentration on tasks

Excellent mental calculation

Improve memory power
â€‹

Excellent mental processing

Develop positive attitude towards math

Selfconfidence and selfesteem

Development of the left and right brain
We are the first TwoHand Abacus Training Program in the Bay Area!
â€‹
Why TwoHand?
â€‹
Instead of using a single hand at abacus training, we advocate the use of both hands to manipulate the beads on the abacus.
After students have learned the basics of the abacus, they are trained to mentally operate the abacus in their brain.
â€‹
Mental arithmetic approach requires the combined use of both sides of the brain. The movement of both hands activates both the left brain and right brain.

“By visualizing an abacus to perform mental calculations, abacus users were able to make significantly more use of their right brain; therefore achieving a simultaneous and balanced usage of both brain hemispheres.”

Why abacus? Why base10?
Why not verbal counting?
What’s wrong with our Numerical Linguistic System?
â€‹
Children in East Asian countries are more likely to learn to use the abacus along with their base10 numerical linguistic system and tend to master mental calculations earlier and more efficiently than their peers in other countries.
â€‹
For most Englishspeaking children, they struggle with math when they are young because their numerical linguistic system does not match with arabic numerals in a base10 system.
â€‹
If the English numerical linguistic system has made simple arithmetic difficult, why don’t we use the abacus base10 system to make it easier?
â€‹
Wait…too many numbers!

6 + 8 = ? You may count verbally to solve this problem. But how about 1683 + 2059 = ? How about 38 x 25?
