Mental arithmetic is a skill that can be cultivated initially by adopting the pen or bead. In the pen method we use pen and paper to perform the calculation. In the bead method we use an imaginary abacus in our minds to calculate and arrive at the answer. We can use the bead method to perform addition, subtraction, multiplication, and division. The different methods of calculation can be divided into:
Dictation:This is also called "Mental arithmetic calculation through listening’ to the sum/problem ". Someone will read aloud the numbers and the listener will perform the calculation.
Observation: The person will use the numbers that he sees and imagines the numbers to be the beads on an abacus. He will use this imaginary abacus to perform the calculation.
Silent Dication: The person will dictate the number to himself silently and use an imaginary abacus to perform the calculation.
Operating Abacus and performing Arithmetic Process involves regular Solving by the way of Oral Math Question Solving Dictation and Solving by the way of Reading Dictated Math Question involves most of the sensory parts like Fingers, Hands, Eyes and Ears to co-ordinate with Mind for time to find a math result. This continuous practice of TIME (PLUS) ATTENTION with increasing difficulty levels by way of more numbers per question and time target to solve set of questions is nothing but improved concentration.
Dictation by various master trainers at different speed levels will increase the ability to concentrate. All skills are developed by practice. Keep practicing and you will be able to pay attention to the numbers. This ability will transfer to the classroom and to your environment. The cost will be Rs.400/-
