DeHe, the only way I was able to get letters and numbers facing the right way is that I had a reliable picture of the lower case A in my head and I remembered ALL other letters, and even eventually numbers relative to the A. I think I remembered the A with some freaking relationship to my handedness, which I was only able to remember by holding out my hand to pick up a pencil. These were the bizarre coping mechanisms I came up with my issues were never even noticed really, let alone remediated, so I am not suggesting he do as I did exactly. But perhaps some reference point to refer to is why he has sorted the alphabet but he hasn't found something similar for numbers?
