The main purpose of introducing 'mapping' in the primary Mathematics curriculum is/are A. to promote spatial thinking B. to promote proportional reasoning C. to make subject easy and interesting D. to break the monotony of numbers

The main purposes of introducing mapping in primary mathematics curriculum are to promote spatial thinking (A) and proportional reasoning (B). Maps require understanding of spatial relationships, directions, and orientation, while also involving scaling and proportional thinking when converting real distances to map distances. These are important mathematical skills that go beyond just numbers and provide a meaningful context for mathematical reasoning.
