Cognitive science and maths education

Interesting article in the New York Times on application of cognitive science on education.
Suggesting that children are better at maths than is often assumed. Talks about a method where numbers are learnt by recognising how many there are by sight rather than counting. Also preschool ability for simple division (sharing).
Also of note ”A study published in March by neuroscientists at Maastricht University in the Netherlands suggested that the brain does not fully fuse letters and sounds until about age 11”
