IPA Sounds and their letters
This is yet another definitive work. There are 53 IPA letters of every sound in words and pictures linked to their phonics (sound) and graphemes (written letter symbols).
As a teaching resorce, this book of lists is a perfect springboard for teacher-directed language activities. These include spelling, creative work (both oral and written), dictionary games, research skill development, reporting, hearing small differences in words, and much more.
