TO TEACH SIGHT READING YOU NEED...
Carefully and thoughtfully graded
material, and lots of it.
I would highly recommend buying these
five books and keeping them handy to have a steady supply of new
material to set in front of your students. Just a few minutes each
class, if done regularly and consistently, is bound to make them
better readers.
