Why don't we use to before home when we use at before it?

Please give me an example and I'll correct it with you.

Your question is not clear to me.

I mean we use the preposition 'at' with the word 'home' but why can't we use the preposition 'to' with the word 'home' such as:

I'm at home now doing nothing.

I'm going home now. It's too late.

OK I think I understand.

In English we write or say, I am going home...not I am going "to" home. It's an exception (present continuous).

It's confusing, especially since you can write or say "I am going to school" or "I am going to Church". It's an exception that you just have to learn.

Of course, you can always say "I am going to my home".

My students asked me that why can't we use "to" with the word home but we can use "to" with another words

No special reason.
It's just idiomatic.
