There is nothing wrong with the question itself. Only 0-9 can be filled in the blank of the question, and there is no place to fill in 10. There is also a sentence "among these numbers" below. "These numbers" can only be the numbers in the above table. The numbers greater than 7 are naturally only 8 and 9, and the largest of these numbers is 9, which is correct.

The teacher thinks that the maximum number is 10, which is estimated to be the number from 0 to 10 just after teaching, and thinks that the maximum number in children's cognition should be 10. Obviously illogical, the child's answer is 9, indicating that the child's logical thinking is meticulous and thoughtful.

This should not be wrong, it will discourage children.

If you want to take the test 10, you should be more rigorous, and the space above should be left 10, which is reasonable!

I think, as a teacher, we should give all ambiguous questions right, encourage children more, and should not discourage children in this way. It seems insignificant, but it is a considerable blow to a child.

I have had personal experience, that is, I made a big mistake in the senior high school entrance examination, but I remember it correctly and wrongly.
