“Number sense can be described as a good intuition about numbers and their relationships. It develops gradually as a result of exploring numbers, visualizing them in a variety of contexts, and relating them in ways that are not limited by traditional algorithms.”  (Van de Walle et al., 2005)

Information about Number Sense

As part of my Elementary Math Methods class at Kansas State University, my students contributed to this padlet summarizing number sense: https://padlet.com/chepina_rumsey/zo2bvpjjrrfy

“Number Sense Series: Developing Early Number Sense” (Way, 2011). The NRICH website has a lot of great resources and activities. https://nrich.maths.org/2477
