According to National Curriculum Framework, 2005 ________must be given least importance in mathematics at primary level.

Correct option is B

According to the National Curriculum Framework, 2005, the emphasis at the primary level of mathematics education should be on developing children's understanding of mathematical concepts, fostering their interest in mathematics, and equipping them with basic problem-solving skills. Precision, which involves focusing on exactness and accuracy, is considered less important at this stage as it can hinder the development of conceptual understanding and creativity. At the primary level, the focus should be on developing children's broad mathematical understanding and problem-solving abilities, rather than emphasizing precision and rigor.
