Consonant Sounds /g/ and /j/
The Page Consonant Sounds by Spelling now has an extensive collection of word lists covering the various spellings of the /g/ and the /j/ sounds.
The /g/ and /j/ sounds are listed together because of the overlap of the letter g which can be the /g/ sound in words like grab and got as well as the /j/ sound in words like gem and gist.
In the OnTrack Reading curriculum, a Rule of g is only obliquely referenced because it is not as reliable as the Rule of c. Nonetheless, a very similar pattern does occur and it involves the same trailing vowel letters, e, i and y. While I will teach every client, no matter how young, the Rule of c once they get into longer multisyllable words, I rarely get into anything like a Rule of g except with some of the older clients (5th grade and up or so) who might be more likely to deal with the inconsistencies encountered.
Besides, teaching the digraphs ge and dge for the sound /j/ goes a long ways toward training the concept that the letter g usually represents the /j/ sound in front of the letter e and that is the most prevalent situation covered by the “rule” anyway.
