When your child’s got the concept of reading down, here are books to help with practice (and it takes lots and lots and lots of practice; be very, very patient–and keep reading aloud the fun, interesting, good books that they can’t read yet).
Teach Your Child to Read with Children’s Books by Mark Thogmartin (he has a new edition coming out and I’m hoping book lists will be updated; this is a great book but many of the books are becoming out of print)
Usborne’s Help Your Child Learn to Read (out of print but well worth finding a used copy)
Games for Reading by Peggy Kaye
Games with Books by Peggy Kaye
Games for Writing by Peggy Kaye (her games are great! kids really do learn just by playing)
