INDIAN ABACUS- Colour images
Indian Abacus Program is structured with a special focus to facilitate the children to learn numbers and identify them as colour images, to add, subtract, multiply and divide them in doing the calculations. The importance of identifying the numbers as colour images is a predominantly strong factor that Indian Abacus program could establish with the strength of the Indian Abacus tool. This is a conspicuously lacking feature in the conventional abacus in use now due to the inherent inadequacy in the Abacus tool which has beads which when manipulated to move towards a value position retain their original image and do not emerge as a disclosed colour image as an output of the systematic manipulation.
Whereas in Indian Abacus, when the child moves a specific slider to a value position with the finger, the kinesthetic activity (touching and moving) is one which gets completed. Simultaneously, the slider which is moved towards the bar results in a colour image emerging, which is a visual. So there are two strong features of information and & related memory registry that become available for the child one to feel the touch and the other to see visually. Visual, the input for the sight has a greater impact on the brain for it to receive and store the information as memory.
In the Abacus the conventional one - the bead when moved towards the bar, no doubt the kinesthetic activity gets completed but with regard to the image registry the bead before and after moving retains its unchanged image, so it is received as a comparatively weaker image (due to the crowded matrix of beads and lacking distinction) hence the initial learning becomes difficult, a little stressful and the memory registry is also that much fragile. The children especially the very young ones of the age group 5 to 7 years find the visual learning difficult and less effective with the conventional abacus. The drop outs in the initial levels and errors in calculation experienced could be related to the difficulty in visual learning and the shortcomings thereof.
Manipulation of the slider images using physical Indian Abacus during initial learning phase and practice and using mental abacus in the later stages in the process of doing arithmetic calculations are meant to attain speed in calculations and to maintain accuracy throughout. This process makes the child concentrate well on the images created and re-created to finally fix on the image for the answer. In the process of calculations using abacus there are a number of stages. A direct addition involving a simple movement of slider image/s in one or two slots or it could be moving up and down of slider images in different slots for executing a formula based working to add or subtract. Concentration on every movement of the slider image and every resultant slider image and incorporation of specific formulas to add or subtract number/s of a sum and the final answer in the form of an image, apparently look to be a single activity of focus falling under Concentration but considering the various constituents as stages of calculations, they are all individual and collective objectives of focus.
