Starting an answer with “I think”

[HastingsLikeTheBattle]

DD2 has just been doing a compression exercise at home (not school homework, she just loves them) and we were going through her answers. She’s Y6, bright but as this was an 11+ workbook she’s definitely challenging herself!

A few of her answers started with “I think...” and I said I wasn’t sure that was the best approach as she needed to be confident in her answers. Disclaimer- I’m not a teacher or educational professional. She replied that her teacher had told her class that when they weren’t sure of an answer, to start with “I think”. DD couldn’t remember the explanation as to why.

From what I remember from A level English personal voice was encouraged, but I’m not sure about using it when you’re just not sure of the answer.

Do other schools use this approach please?

I think it's a reasonable sentence starter if what you're going to say is a matter of opinion not a matter of fact. I think this word is an adjective - no. I think Character X is feeling sad because Y, yes.

That makes sense, thanks cat. My difficulty is that the questions were asking for a definitive answer, eg “what is a ...?”.
I think I’ll ask the teacher

Unless it is to indicate to the teacher where a child was unsure?

Not 100% sure, but if there aren't definite answer to the question, like if you are inferring the answer from the text, it's fine to say "I think"?
To me, it's just indicating your opinion, when there are no definite answer.
