Mental Arithmetic

Arithmetic is remarkably important for helping young children build up a solid academic foundation. Teachers who work with young children know that it is not easy to introduce the concept of numbers and their values. It is a long learning process for young children to comprehend the concepts of mathematics when presented only in the abstract form. By abstract it means using nothing but brain power to solve problems. It is difficult for children to comprehend numeric relationships without using a concrete object such as the abacus beads to relate numerical values.
