Number Sense = Mathematical Common Sense

Number sense is something we like to call “mathematical common sense”. Students with number sense skills are good with numbers,

which means they are good with math facts, counting, adding, subtracting, and identifying common sets with relative ease. These students also intuitively and efficiently identify number relationships, make mathematical judgments based on prior knowledge, and solve mathematical problems.

Research studies show that kindergartners who do not develop number sense while in kindergarten are highly likely to develop math difficulties in later grades. These problems are likely to persist and require substantial and costly intervention.

Kids’ Education for Number Sense (KENS Math) is a supplementary curriculum that targets three specific components of number sense.

  • Teaching young learners to subitize or quickly identify the number of items in a small set without counting.
  • Teaching young learners to order numbers on a number line and recognize the relative magnitude of these numbers (how much greater one number is than another number).
  • Teaching young learners to compose and decompose numbers – know the sum of single-digits numbers without counting.

This early education math curriculum is specifically designed to meet the needs of students with varying abilities by addressing perceptual and conceptual number sense skills. The perceptual skill of subitizing relies on the brain’s almost autonomic response to identify small sets of number. It interconnects with conceptual skills that include recognizing number relationships. Read more about subitizing.
