I'm trying to actually figure out how I handle this myself. I definitely don't visualize numbers to nearly the extent of the OP, but I guess I do to some extent kiiind of 'see' the blocks of 10. IE if I add 8 + 5, I do think of the 5 splitting into a 2 and a 3, and I guess there's an.. almost visual aspect to it. It's just in situations with carries though; I certainly don't visualize each number as a different shape.
