The best definition of number sense for students in kindergarten to fifth grade is a student's overall understanding of numbers and their relationships. This definition encompasses several fundamental aspects of mathematical thinking that are crucial at this developmental stage.

Number sense includes not just the ability to recognize and work with numbers, but also the comprehension of how those numbers interact with one another through various operations such as addition, subtraction, multiplication, and division. It involves understanding concepts such as greater than, less than, and the effects of combining numbers in different ways, which lays the foundation for more advanced mathematical concepts later on.

This broad understanding helps students develop the skills necessary to approach problem-solving with confidence. It allows them to use numbers flexibly, understand numerical patterns, and make reasonable estimates, enhancing their overall mathematical readiness. Additionally, this foundational knowledge is vital for their success in more complex arithmetic and algebraic operations as they progress in their education.

In contrast, the other definitions may capture important elements of number sense but do not encompass its overall scope as effectively. For example, understanding quantities and abstract representations contribute to number sense but are not as comprehensive as the overall understanding and relationships that students must grasp.
