[jlamber]

Hello,

I am trying to create a number line such as those on page six of this paper

I have looked at coordsys package but it's hard to control the interval and the length of the number line. Do you have any other suggestions?

Please help.
Thank You,
John

One option is to use TikZ. Load the package with \usepackage{tikz}, and then do something like this:

\begin{tikzpicture}[font=\Large]
\draw (0,0) -- (12.5,0);
\foreach \x in {0,3,6,9,12}
\draw[shift={(\x,0)},color=black] (0pt,3pt) -- (0pt,0pt);
\foreach \x in {0,1,2,3,4,5,6,7,8,9,10,11,12}
\draw[shift={(\x,0)},color=black] (0pt,0pt) -- (0pt,-3pt) node[below] 
{$\frac{\x}{3}$};
\draw (0,0) node[above]{$0$};
\draw (3,0) node[above]{$1$};
\draw (6,0) node[above]{$2$};
\draw (9,0) node[above]{$3$};
\draw (12,0) node[above]{$4$};
\end{tikzpicture}

The above code produces output like in the attached PDF. Note that I know very little of LaTeX compared to some other people here, so there may well be better options available.

I may venture some modifications to the code of torbjorn t. that optimize it slightly.

\documentclass{minimal}
\usepackage{tikz}

\begin{document}
  \begin{tikzpicture}[thick]
    \draw(0,0)--(12.5,0);
    \foreach \x/\xtext in {0/0,3/1,6/2,9/3,12/4}
      \draw(\x,0pt)--(\x,3pt) node[above] {\xtext};
    \foreach \x in {0,1,...,12}
      \draw(\x,0pt)--(\x,-3pt) node[below] {$\frac{\x}{3}$};
  \end{tikzpicture}
\end{document}

For more information refer to the pgf/tikZ manual. Could be done similar with pstricks.
