The children learning have to strain the eyes a bit to isolate ‘the value beads from no- value beads. Children are prone to commit errors in calculations and also the deficiency to provide clarity strains the children. Poor sight and more intense focus required reduces the speed of calculations.

Children’s attention is drawn by every moved slider for a value, as the moving of the slider towards the bar unhides the colour image. Stimulus is greater, hence strain is less. Learning will be therefore easy through quicker comprehension. Speed is enhanced since reflexes will be fast.
