@Linzeyhun, that to me suggests that the girl perhaps had something else going on in her head that day. Maybe she wasn't feeling very well. Maybe there is trouble of some sort at home and she was distracted. I used to help in my son's class and I remember that the capable children who generally worked hard were consistent about that. I'd have been concerned about her rather than punitive in your shoes.
I vividly remember being a small child at school, actually. I started school just after my fifth birthday. I was one of the very youngest in the class at an academically selective school which I'd got into by mistake (long story!). I couldn't read. My mother was a primary school teacher and had made the conscious decision not to teach me because she thought it might be confusing for me if my teacher used a different method. She'd talked and read to me a lot, I knew my colours, numbers and so on, but I couldn't read.
Everyone else in the class could read, or so it seemed to me. My teacher was very clearly extremely irritated to find that she had a new child who couldn't read and couldn't keep up. I remember sitting in class wondering what I was supposed to be doing and how it was that everybody else seemed to understand. One day as I came in I knocked something over and she made a dismissive remark to another teacher about me, which I heard and which cut me to the quick.
Fortunately for me - very, very fortunately - we moved house at the end of my first term. I went to a bog standard local school after that. By the summer I was reading and writing so fluently that I wrote and illustrated a little book, which I still have. At the risk of sounding very bigheaded, I was a clever, bookish child who went on to do very well academically all the rest of my time in education. That first teacher didn't see that in me, she just saw a nuisance who didn't fit the template she had for her pupils. If I'd been in that environment for longer it would have damaged me.
One of the things teachers need more than anything, it seems to me, is kindness and empathy for children. They should like children. I'm not getting any sense from your posts that you like children. That's sad.
