Number Line

Type: tool

A number line is helpful for visualizing counting.

\begin{tikzpicture}[x=1.15cm,y=1cm]
  \draw[<->, line width=0.8pt] (-3.65,0) -- (3.65,0);
  \foreach \x in {-3,-2,-1,0,1,2,3} {
    \draw[line width=0.8pt] (\x,-0.13) -- (\x,0.13);
    \node[below=4pt] at (\x,-0.13) {$\x$};
  }
\end{tikzpicture}

We can put arrows to indicate which direction we count in.
