About Number Sense
Subitizing
Subitizing is the ability to instantly recognize small quantities (1-4) without counting. Beyond 5 items, we switch to estimation or counting. This is an innate ability shared with many animals.
Estimation Strategies
For larger quantities, experts use clustering (count one cluster, multiply) or reference points (compare to known quantities). Estimation accuracy improves with practice and math skills.
