So, I was taking DD6 back from swimming this morning - with 4 kids it's rare that she and I have much one on one time during the day. Anyway, she was looking out the window at the scenery and traffic and announced that many common objects she thinks of by their "number". So, 'car' is number 9, 'tree' is 4, her immediate family all have numbers and so on. She said that if she's doing boring maths in the class and sees the number 9 she automatically thinks of a car but if it's interesting maths she only sees the numbers.

Is this really weird? Or common for a gifted mathy kid?

It makes me a bit uncomfortable but I'm not sure why.
