[bobert]

Would the following translations be correct, given the context represented in the image? Thanks!

Write twenty sentences on the blackboard!
Напишите двадцать предложений на классной доске!

I will not do anything bad ever again.
Я не буду ничего плохого делать никогда.

1] Whether or not напиши or напишите is used depends on the situation I suppose. I believe Russian does fall into the category of languages that uses the informal (ты) when an adult speaks to a child, regardless of relation.
предложе́ние literally means pre-pose-al (pose~*ложить), but does mean sentence as well; all good there with cases and whatnot.
I......... would think you would say "write onto something" with на + acc, otherwise you're standing on top of the board while you write. Could be wrong.
классая доска is blackboard for classes-- that's correct. I'm fairly sure I've seen cases where классная is left out due to sufficient context.

2] Я больше не сделаю ничего плохого.
Idunno... Nothing in Russian will line up word for word because of double negatives and the way Russian expresses "again". I can imagine the argument for Imperfective being used here, and it sure seems convincing enough to me, but it may very well be downright wrong.

• If the phrase is said by a teacher in a classroom, blackboard is just доска, not классная доска. The latter is used only outside the context for disambiguation reasons.
• I’d omit the word предложений and used the word раз ‘times’ instead.
• I will not … ever again. — Я больше никогда не буду … (imperf. infinitive) or just Я больше не буду … (imperf. infinitive)
• The most hard thing for me is translating to do (something) bad. I think, it would be better to replace it with something more specific according to the context. E. g. хулиганить ‘behave like a hooligan’.

Напиши́ на доске́ два́дцать раз: «Я бо́льше никогда́ не бу́ду хулига́нить».


(As far as I know, the tradition of writing lines on the blackboard as a punitive measure does not exist in Russian/Soviet schools.)

Yes.

Написать на доске (prep.) is correct.
One can say переписать из книги на доску or maybe выписать на доску, but not писать/написать. Dunno why.
