Your Kid May Already Understand Numbers And Basic Math

Babies as young as 3 months can detect changes in quantities of objects, and their comprehension of numbers increases from there. At 6 months, babies can distinguish in ratios of 2:1, and by 10 months that improves to 3:2. There’s even evidence that they can perform basic arithmetic, displaying an understanding that certain outcomes of numerical visualizations were “wrong.” Researchers believe this stuff is hardwired into our brains at birth, since studies suggest monkey brains respond in similar ways. So, the good news is your kid is way smarter than you thought; the bad news is your kid isn’t much smarter than a monkey.
