It All Adds Up for Kindergarteners

See, I have been saying this for a long time! Math should start sooner in school. :)
It All Adds Up for Kindergarteners: "Preschoolers with no conscious understanding of arithmetic were still able to add two numbers and compare the total to another number. They weren't as accurate as a calculator, but that's not the point, said study co-author Elizabeth Spelke, a professor of psychology at Harvard University.

'What we've shown in the children is an ability to get to approximately the right answer,' she said. And that, she added, gives educators more insight into the 'building blocks' of mathematical knowledge."
