Sight Reading Books for Piano

A few days ago, I searched sight reading/playing books for teaching piano. And luckily, I got it for free. :) The books are from grade 1 - 8. You can just download and print them. Like I did, and I use them already for my teaching. Here's the link.

1. Grade 1
2. Grade 2
3. Grade 3
4. Grade 4
5. Grade 5
6. Grade 6
7. Grade 7
8. Grade 8

Enjoy :)
