Lion Brand yarn's website provides a comprehensive and complete tutorial and here is the link to cut/paste into your browser:
Once on the page, towards the bottom center where it reads "Learn to Crochet: Before you Start" there is a link below to the left where one can download ALL of the directions (rather than view online page after page). This is what I suggest.
I contacted Lion Brand asking permission to reprint and utilize its instructions for teaching, and the response was "ABSOLUTELY, yes" - so long as I left the Lion Brand copyright on the papers -- which is what I do. Another good thing about its site is the variety of patterns for all categories and experience levels - AND - Lion Brand doesn't mind if you plan to sell what you make using their patterns. Over all, good website with lots of useful stuff.
Another good learning site is: http://www.nexstitch.com/a_articles.html This takes you to the instructions base, which are pdf downloads. There, one can even find instructions for left handed crocheters.
Happy learning to you all.
