My daughter is on the young end of teenager.
BUT - she came home BEAMING because the teacher TOOK HER SUGGESTION SERIOUSLY.
So, I would say let them have input. She was ecstatic because he was talking about the field trip to the Museum of Science and Industry and she said that they go there every year and this year in science they are studying constellations and could they please go to Adler Planetarium because it fit better with the plan (I would have jumped up and down if she could have uttered curriculum, but I take what I can get!!!!!!).
He said - I see your point. Let me see what I can do. I'm not sure if I can change it, but it makes sense that we would go where we are studying.
She said to me "even if we don't go there.... Mom, he LISTENED to me and will think about what I said".
I think this age is all about that. so, do that where you can.
Good Luck.
