Lexile codes:
When looking for a book at your reading level, use the Five Finger Rule:
1) Find a book and read the first page or two.
2) Put one finger up for every word you don't know.
3) If five of your fingers go up while reading, find another book.
If less than five fingers go up, then you found a book at your reading level.
