Are they negative items?

Hi guys,
I'm analyzing a questionnaire using a 3-likert scale (Agree - Not sure - Disagree).

There are some items that I want to make sure they are negative to choose the right code for them.

1. I can do some tasks and activities without thinking about what I am doing.
2. As long as I remember what I have done with my group, I do not need to think too much about what I will do alone.
3. If I follow what the teacher says in the class, I do not need to think too much about this program.

If a student responds "Agree" to any of the items above, which code I use ?
1 or 3?
I am looking forward to hearing from you!
