Description: Have you ever tried to guess how many jelly beans are in a jar without counting? The Panamath test measures your number sense -- your intuitive recognition of numbers and their relationships -- and approximate number system (ANS) aptitude. Practice estimating quantities online or with the free download; see classroom tips for giving the test, example studies, and journal articles. The "pana" in Panamath stands for Psychological Assessment of Numerical Ability, an acronym that "also highlights how the approximate number system is found everywhere -- in people and in animals all over the world." Hosted at Johns Hopkins University, with funding from the National Science Foundation (NSF).
