Thanks for your info.
But what I am asking for is that if my grammar correct here in the question?

I am still beginning to learn Japanese Grammar
Did you play yesterday?

And what I studied so far is that "didn't" is not in Japanese but it makes the verb in Past tense and adds the suffix "mashita" to the verb "wakarimashita"

And I also learned that we don't need to mention pronouns in our Japanese questions, so "you" is not needed.

So, we only have the verb here and "yesterday"...
I studied that "play" means "shimasu" just like "do" which has the same meaning "Shimasu"....

I studied that words of adverbs of time like "yesterday" "tomorrow" and "today" comes at the beginning of the sentence... and that I don't forget to add "ka" to the form of the verb to make the sentence a question.....

So, from applying these grammar lessons I answered:-
Kinou shimashitaka.
きのうしましたか。
Did you eat yesterday?
Kinou tabemashitaka.
きのうたべましたか。

If I have an object like:
Did you read a book yesterday?

I studied that we use the word 'yesterday" before the object and then we use the object and an object marker after it then we end the question with our verb having "ka" at it's end.

kinou hon o yomimashitaka.
きのうほんをよみましたか。
