FunnyStrange

"Funny" can mean "strange", but it can also mean "amusing". I think that "strange" would be better here because I kept waiting for an amusing moment while I was reading your post, but it never came.

In themy morning reading class, after I turned off the radio, none of the students kept reading.

If you say "In *the* morning reading class", it suggests that we're familiar with it already. But this is the first sentence of the post, so "my" is better.

More generally, it's not clear what you mean here. Do you usually play the radio and have students read something along with it, with the understanding that when you turn it off, they're supposed to keep reading? I'm having trouble understanding how that's supposed to work.

I blametold them that they were quiet when they were asked to read, on the contrarybut when they were asked to be quiet, they were noisy.

"Blame" means to assign someone the responsibility for something that went wrong. But here you're not trying to figure out who is responsible; you're criticizing their behavior. If you want to emphasize the criticism, you could say:

I criticized them for being quiet when they were asked to read, but noisy when they were asked to be quiet.

They kept silent, ev. Even when the headmaster appeared, they were [as] silent as stones.

There was a comma splice in the original (a comma joining two sentences that can stand alone on their own).

Wieirdly, the headmaster said nothing, because she usually would talk with the teacher or students about the bad performancebehavior.

When the bell rang, nobody moved as usual, tthey usually do. They still were silent.

another comma splice

It was really surpriseding and funnystrange.

There were ten of mythe students were mine.

Then I sayid nothing and went to the office.

Did they know they were supposed to go to the office, too?

However, some of them walked into the classroom instead.

I stepped in,to the classroom and said angrily, "Who told you that you can come back?"

Then I walked into the office, and told them that I've reminded them countless times to put on the whole uniform all day for countless times, but they didn't take it seriously.

Since I was unable to handle their problem so that, I would poset the picture on the parents' chat group to ask the parents for help.

I took out a handbook which records the details of students' bad behaviour details, and asked them to sign.

I looked out, t. There wasere several boys walking in the corridor.

It was time for math class, so they should not have been there.

Thus,When I went to the classroom and, I saw nobody there.

He answered that they had wentgone running.

I had told them to run 5 laps last night.

BHowever, because the playground was wet now, I didn't askexpect them to run. today. [?]

Is this what you meant?

Also, I'm puzzled by what you told them the night before. Did you tell them that you wanted them to run five laps every day?

I said to the boy, "It is time for math class, j. Just tell them to go back to have class."

I went to the end of the corridor and looked at the playground, s. Some boys had nearly finished one lap whilebut all the girls were falling behind.

The girls didn't stop until they had run one lap.

What about the boys?

Ms. Li said that it seemed they were really scared of me.

Was it the fact that the girls completed the lap that made it seem as though they were scared of you? Or something else?

"If they really were, they wouldn't be so noisy ," I replied.

Note that there shouldn't be a space before a comma.

I know the it is unfair to punish the guys who didn't violate the rules.

But since most of them were noisy, I caouldn't accurately found out whoich ones were making noise.
