In non-human animals, number sense is not the ability to count, but the ability to perceive changes in the number of things in a collection. All mammals, and most birds, will notice if there is a change in the number of their young nearby. Many birds can distinguish two from three.

has made number sense a focus area of pre-K through 2nd grade mathematics education. An active area of research is to create and test teaching strategies to develop children's number sense. Number sense also refers to the contest hosted by the

is the term used for the hypothesis that some animals, particularly humans, have a biologically determined ability that allows them to represent and manipulate large numerical quantities. The term was popularized by
