Children understand the concept of number size through innate approximate number systems
the verdict
SUPPORTED
the evidence backs this
confidence 64/100
Evidence largely supports the idea that children and infants possess an early, intuitive approximate number system that helps them understand numerical magnitude and size, though researchers debate the extent to which non-numerical visual cues influence these early tasks.
