Need help for a simple script - Is what I have the only way?

Hello this is my first post!

I'm making a little script that reads a text file.

#/bin/bash
COUNTER=1
while read line
do
    echo "$COUNTER"
        COUNTER=`expr $COUNTER + 1`
done < mytextfile

I simply want to print the line number I'm currently reading but isn't there a more simple way to do this than what I have above?
Is the only way to do this is by using a temporary variable?
Thanks in advance

This sounds a lot like homework....

Well it's not like I don't know how to do what I want but I thought it'd be nice to know other ways by experienced people.
