A mathematics teacher is planning lessons on basic arithmetic operations. She notes that students who have a strong number sense understand addition and subtraction more easily. Later, these students grasp multiplication and division concepts because they build upon prior knowledge of addition. The teacher emphasizes the importance of sequencing topics so that each new concept connects logically to what students have already learned. This approach helps students develop a deeper understanding and avoids misconceptions that arise when topics are taught in isolation. Which of the following statements appropriately explain the hierarchical nature of mathematics? A) Multiplication follows and builds on the concept of addition. B) Addition and multiplication are distinct concepts independent of each other. C) Mathematical concepts should only be assessed through summative assessments. D) Number sense needs to be developed before the concepts of addition and subtraction.
