One of the best places to learn about phonics (other than here, of course!) is the book “Phonics from A to Z” by Wiley Blevins. It is one of my phonics favs, and provides tons of great information is a way that is understandable. He provides word lists for each phonogram, books to read for phonics patterns, and much more. One of the things I especially like are the charts that show the frequencies of patterns.
A chart that shows the frequencies of long vowel patterns from the Phonics Pow Toolkit is based on a pdf of English-Language Spelling Pattern Generalizations at anyflip.com.
