I like to think of number sense as the linchpin to learning mathematics well. It plays a critical role in students’ confidence and risk taking. It helps them determine the reasonableness of their solutions and tinker with strategies and approaches when their solutions to problems are off. Number sense enables students to be flexible and efficient with both their computation and reasoning.
