Article in English: Since you're taking the time to research and draw your family tree, pick out nice drawing materials so that the information is presented well.  Art supply stores sell individual sheets of large paper. Choose one that is sturdy and attractive, such as watercolor paper. A more convenient option might be a piece of posterboard. This type of paper is also sold by the individual sheet, and it comes in a variety of colors. You can find it at drugstores. Plan to draw the family tree in pencil and trace over it with a nice ink pen or marker. Some family trees are drawn in the shape of actual trees that have a branch for each "branch" of the family. Others are more like family diagrams; the end effect is tree-like, but the family names aren't actually superimposed on a tree drawing. Use the style that was assigned to you in class or simply choose the one you prefer.
