Five Finger Rule
1. Open the book to the middle of and choose any page to read.
2. Read the page.
3. Put out 1 finger for every word you do not know or cannot pronounce.
4. If you have 5 fingers out, the book is too difficult to read without help.
5. If you do not get any fingers up, but are reading very slowly and decoding almost every world, you will not enjoy the book.
Here's the finger guide:
1Finger: This book is okay for you.
2 Fingers: Still good.
3 Fingers: Could be a bit hard for you to understand.
4 Fingers: Will be too difficult to read and understand.
5 Fingers: Choose another book.
