Why Number Sense?

Number sense is important because it encourages students to think flexibly and promotes confidence with numbers. A strong number sense provides the foundation needed for both simple and complex arithmetic. It refers to a child's fluidity and flexibility with numbers, the sense of what numbers mean and an ability to perform mental mathematics and to look at the world and make comparisons.
