“For children to grasp number sense, they need to understand that an abstract symbol (the number 3 or 8, for example) means an amount or quantity that could apply to anything. They need to learn that the number 7 can stand for the girls in the room, cups in a box, blocks on a table, pieces of a puzzle or how many scrapes they have on their leg. And they need to learn that a 6 stands for fewer things than a 9, even though there’s no way to understand that just by looking at the numbers themselves.”(more)
