Doing Mental maths or mental calculation is a process where one performs the calculation without the help of any paper, calculator or any other external medium. They perform the calculations depending on their mental ability. Mental maths involves calculating by listening, data storage and processing, logical implementation of desired functions to solve and to reproduce the answers confidently & correctly. All these are done in few seconds with accuracy.
The minimal involvement of time and the precise accuracy in doing mental maths adds to the maths learning ability of an individual.
Abacus course training is initiated in a child with a set of rules. Initially the child learns to use the Abacus tool to give the correct answer. Gradually the child learns to visualize and imagine an abacus, while the actual tool is removed. The child is then taught to calculate normally like they would do on abacus, but this time they will use the visualized abacus. Over a period the child confidently does larger digit calculations with speed and accuracy, without the aid of any tool. His mental learning abilities are enhanced and so is his accuracy in mental maths
Teaching a child Math is not a child play. Scholars since ages have been mulling over it so as to design methods that could increase the inclination of a child towards numbers. The ancient tool abacus has proved to be the best instrument to help teach a child maths. 'Child Maths' can become a child's play with the help of an abacus & SBS.
