Millions of high school and college algebra students are united in a shared agony over solving for x and y, and for those to whom the answers don’t come easily, it gets worse: Most preschoolers and kindergarteners can do some algebra before even entering a math class.
In a recently published study in the journal Developmental Science, lead author and post-doctoral fellow Melissa Kibbe and Lisa Feigenson, associate professor of psychological and brain scienes at Johns Hopkins University’s Krieger School of Arts and Sciences, find that most preschoolers and kindergarteners, or children between 4 and 6, can do basic algebra naturally.
“These very young children, some of whom are just learning to count, and few of whom have even gone to school yet, are doing basic algebra and with little effort,” Kibbe said. “They do it by using what we call their ‘Approximate Number System:’ their gut-level, inborn sense of quantity and number.”
The “Approximate Number System,” or ANS, is also called “number sense,” and describes humans’ and animals’ ability to quickly size up the quantity of objects in their everyday environments. Humans and a host of other animals are born with this ability and it’s probably an evolutionary adaptation to help human and animal ancestors survive in the wild, scientists say.
