Question : linq to sql how to model claases

I am using linq to sql to build questionnaire app.  
I want to build structure the classes in a logical way.
So I will have questionnaire class and question class and so on

My question is this;  what properties and methods will I need on each class?

So say I want to create a new questionnaire full of questions willl I have a questionnaire class that then links to the question class?

So  like

questionnnaire.AddNewQuestion("text");
