Re: "Do you think when to start?" or "When do you think to start?"

Neither one is correct. Perhaps you mean "When are you thinking of starting?" or "When do you think you will start?"

What is the context? What exactly are you asking the person about?

Re: "Do you think when to start?" or "When do you think to start?"

I found the first sentence in a handout by a junior high school teacher in Japan, at which my daughter studies. It has no context. It is used to explain the use of "what to buy", "how to drive a car", and so on. Something seems to be wrong with the first one. So I wrote the second one, but it is still strange...

I suppose the teacher wants to mean "When should we start? Are thinking of that?".

What do you say in that case?

The sentence from the handout is meaningless. When should we start? is correct and natural but I can't guess whether it's what the teacher meant to ask.
