Number Sense - Part 1

What Is Number Sense?
Number sense is about a student’s ability to work and use numbers.
To know what numbers mean, understands what their relationship is to one another, perform mental maths, understand symbolic representations and use numbers in real world situations.  

It is about
what numbers mean
number relationships
number size or magnitude
ability to carry out operations involving numbers 
knowing numbers and quantities
Why is it important?
Number sense is important because it encourages students to think flexibly and promotes confidence with numbers.

 If students lack number sense they have trouble developing the foundation needed for even simple maths. 

  • We need to model different methods for computing

  • We need to ask students regularly to calculate mentally

  • Have many class discussions about strategies for computing

  • Make estimations everyday

  • Question students about how they reason numerically

  • Pose numerical problems that have more than one possible answer
