The Indian Abacus is a "A Tool for calculation and Brain skills". The nimble fingers of a young child could manipulate the sliders for calculation purposes. It is semi abstract and pictorial with colour display in representing numbers. Numbers are represented by the slider positions displaying colour. Addition and Subtraction Abacus: 2, 3 & 4 digits - 15 rows (with and without decimals) 5 digits - 7 & 8 rows.
Mental: 2 digits - 6, 7, 8, 9 & 10 rows, 2 & 3 digits - 8 rows.
Multiply: 4 digits by 1 digit (Mental) , 2 digits by 2 digits (Abacus & Mental). Divide 5 digits by 1 digit (Mental), 3 & 4 digits by 2 digits (Abacus & Mental).
Decimal sums calculations bring in new challenges to concentration and speed. Practice in the level strengthens both the skills - concentration and speed. Listening based calculations strengthen Listening skills.
Speed writing which is an all - level practice attains a matured phase. Decimal calculations bring in stronger challenge and accomplishment possibilities. Listening skills strengthen further. Content : The advantage in using the Indian Abacus Non-Digital tool is that the children using this tool are able to relate the numbers / values to the slider positions since the colour images provide good clarity in reading the values of the images. This experience will make them confident. They will know the value for every move and also the final answer without any stress. Indian Abacus Non-Digital tool can be used for all levels of the Indian Abacus program. The tool facilitates better learning and practicing to do the arithmetic functions. Skills Acquired: Concentration, Visualization & Memory in addition to the skills acquired to attain speed and accuracy in calculations. They can replay the movement of sliders any number of times and meaningfully understand every move that they make. The children would demonstrate interest in learning Abacus based mental arithmetic calculations using the Indian Abacus Non-Digital Tool due to its user-friendliness. Visualization is the key to better understanding. Visualization is the key to better anchoring on to the object visualized.Visualization enables more reasons to be with the object of experience mentally.Visualization as the right brain routine is the key factor for Abacus to change the Abstract numbers into objective experience, through image capture by the brain.
