## Other Instructional Approaches for Developing Number Sense

Here are some instructional approaches that encompass multiple big ideas and may contribute to the development of students’ number sense:

“Number sense goes well beyond being able to carry out calculations. In fact, in order for students to become flexible and confident in their calculation abilities, and to transfer those abilities to more abstract contexts, students must first develop a strong understanding of numbers in general. A deep understanding of the meaning, roles, comparison, and relationship between numbers is critical to the development of students’ number sense and their computational fluency.” – SK Curriculum, Gr. 2, p. 8
