Step 1. Fingering Method
Before a child will start to work with the abacus method, he must learn the method of fingers. Using their fingers a child learns to keep score from 0 to 99. On the right-hand one finger - it is one count, and on his left hand, each finger - it is a group of ten counts. A child learns perform addition and subtraction using the method of the fingers.
Step 2. The Abacus
In the method of abacus a child learns to tolerate the method of fingers on the abacus board. This method is considered the highest term in the study of arithmetic. Only the right hand is used to handle Abacus. At the bottom of the board are used the thumb and index finger. Board consists of four abacus beads in each row, the index finger is used on top of boards, which has a single beads on each line. Now, with the help of the abacus method a child learns to count mathematical operations such as addition and subtraction, but between 1 and 1,000.
Step 3. Mental Arithmetic
At this stage, a child learns tolerate mathematical operations from abacus board to mind. With or without the use of abacus a child has learned to calculate mentally. Now there is a challenge in front of him - to learn to multiply.
Step 4. Division Method
This level is designed for complex and sophisticated mathematical numbers. Throughout the period of the fourth a child learns the division method of calculation.
Step 5-8. Visualization of Other Functions
In later levels, students learn to perform calculations with larger and complex numbers. We introduce a method of visualization of other functions.
