1. Number Sense
Number sense refers to a person's general understanding of
number and opera1ons along with the ability to use this
understanding in flexible ways to make mathema1cal
judgments and to develop useful strategies for solving complex
problems.
Number sense can refer to an “intui1ve”
understanding of numbers, their magnitude,
rela1onships, and how they are affected by
opera1ons.

2. 2011 research on Number Sense
(2 studies: Univ. of Missouri & Johns Hopkins Univ.)
• A preschooler’s grasp of numbers predicts math performance
in school years
• Early number sense is linked to formal math achievement
(test scores)
• 1st graders that understand numbers, the quanGGes those
numbers represent, and low level arithmeGc will have beIer
success in learning mathemaGcs through the end of 5th grade
• Number Sense correlates with math tests scores through high
school

3. Number Sense is not just…
• CounGng
• Knowing basic facts (+, ‐, x, /)
• ComputaGonal fluency
• StaGng place value

4. Number Sense is more deeply about…
• Comparing, ordering, and equality
• Composing and decomposing numbers
• Reasonableness, esGmaGon, reasoning
• Internalizing value, magnitude, and base 10
