I can't find much on this on the web for some reason...but I was curious about this mental construct: the idea that numbers could have gender (or color) or maybe other characteristics.
I personally have never had this idea, but my sister has told me that's how she thinks of numbers (with both gender and colors) and she's always just been great at mental computation as well. I thought I'd heard that this can help people organize and recall numbers...
My ds8 just piped up the other day about certain numbers being boys or girls. I asked if he'd been talking to his aunt about it, but he said no. It seems kind of neat to me.
Is anyone else (parents or kids) out there thinking of numbers this way?

Just curious about your thoughts or if anyone can point me to any actual research on this.
