The 5-Finger Rule for choosing a “Just right” book
Open a book to the middle and begin reading. For each word you don’t know, put up one finger. If at the end of the page you have:
5 or more fingers up - too hard and challenging, save for later book
4 fingers up - very challenging
2-3 fingers up - just right
0-1 fingers up - too easy
Enjoy Reading!
