Use the 5 Finger Rule
Some parents often make the mistake of choosing a book for their child that is just above grade level. If you’re not sure if the book is too difficult, use the five finger rule. If your child mispronounces five or more words on one page, the book is too hard. If he misses four words, reading will be a challenge, but can be done. In this case, it’s wise for the parent to read two pages, the child to read one, and so on. Children will find more enjoyment in reading when you use this 2:1 ratio. If only two or three mistakes are made, the book is at the child’s interest level and is a-okay. And when your youngster can read an entire page perfectly, the book is likely a bit too easy, but for some very reluctant readers, that is perfectly fine.
