The blurb on the unit 1 (module 1) download page describes this new chart as:
I designed this because a colleague asked me to produce something suitable to send home to parents which would tie in with the latest Alphabetic Code Overview Chart with key phoneme pictures added recently to the free unit 1 - and which complements the new Alphabetic Code Frieze Posters.Just four sides of A4, this handy information chart would benefit school staff and parents. It includes the key phoneme pictures down the left hand column. A grey tinted background highlights the graphemes taught in units 1 to 5 and distinguishes STAGE ONE teaching from STAGE TWO.
