As mentioned in my post about multi-letter phonograms, some reading programs go beyond the letter sounds and primary multi-letter phonograms and also teach advanced phonograms. There are three programs that I’m aware of, which cover advanced phonograms.
“The Writing Road to Reading” covers 17 advanced phonograms. They are: tch, eo, eau, augh, ce, gh, gi, our, di, cu, aigh, sc, ge, rh, eu, sci and pn.
“Spell to Write and Read” covers 21 advanced phonograms. They are: gu, qu (alternate pronunciation to /kw/), augh, gu, our, gi, ge, aigh, cu, sc, et, eu, ai (alternate pronunciation), gh, eau, rh, ae, yr, au (alternate pronunciation), pn and ah.
“Uncovering the Logic of English” covers 33 advanced phonograms. The main reason there are more phonograms on this list than the other lists is because it includes 10 phonograms that are repeats from the primary phonogram list. This program repeats some phonograms in order to introduce more pronunciations of the phonogram, which don’t occur frequently enough to introduce directly, but occur enough to warrant learning the pronunciations at some point after the primary pronunciation(s) have been mastered. For example, EI could initially be taught as making five sounds, but Uncovering the Logic of English covers just three sounds initially and revisits the other two later as an “advanced phonogram.” The full “advanced phonogram” list in “Uncovering the Logic of English” includes: ae, ah, ai (2 alternate pronunciations to long A), aigh, au, ay (alternate pronunciation to long A), cc, ce, cu, eau, ei (2 alternate pronunciations in addition to the long A, long I and long E pronunciations), et, eu, eur, ge, gh, gi, i (1 alternate pronunciation), ie (2 alternate pronunciations), oe (1 alternate pronunciation), oi (1 alternate pronunciation), ot, our, ps, pt, qu (1 alternate pronunciation), rh, s, sc, th, ut, yr, x (1 alternate pronunciation) and z (1 alternate pronunciation).
At the moment, I’m planning to cover 77 phonograms in the Story Hour Academy curriculum. If you estimate that 72 of the 77 are letter sounds and primary multi-letter phonograms, then it would be accurate to say that the Story Hour Academy curriculum will cover 5 advanced phonograms. These will be covered in section 8 of the curriculum, which I’m calling the “More Phonograms” section. This sequence can be reviewed in detail here.
