> I guess a single math class was enough for all of you to recognize all the digits the next day.
I'm curious what makes you think that. My experience with what's going on at my sons school is telling me that the children spends a massive amount of time on getting recognition of digits and letters right.
When I was living in China I had difficulty recognizing handwritten 9's and 1's. Their 9's are less half-circular than Westerner's are, and the 1's have a long stroke the top that looks like a sloppily written 7 to me. I would frequently look at a handwritten number and have to analyze what it was.
