This week we will cover the last of the Short Vowel Rules in Orton Gillingham. So far, we have made it through FLOSS, “K” Rule, and the “J” Rule. The fourth and final short vowel rule is the “CH” Rule.
The “CH” Rule says: -tch is used after one short vowel at the end of one syllable words to spell “ch.”
This means, in a one syllable word where there is a short vowel sound followed by a “ch” sound, the letters –tch are being used to make that sound.
Examples of this rule are:
ă snatch, match, hatch, patch
ĕ sketch, stretch, fetch, etch
ĭ ditch, snitch, stitch, switch
ŏ splotch, scotch, blotch
ŭ clutch, hutch, crutch, Dutch
Of course, as with most rules, there are exceptions. There are four words which should use –tch but they don’t:
In class, we were given the acronym, WØRMS (the O is not really used) to help remember the words.
This word should NOT have –tch (because it is a multi-syllabic word) but it does: dispatch
Someone learning this rule might have a desire to put –tch after every short vowel they hear, especially in a one syllable word like, lunch.
It is important to distinguish that if there is a consonant between the short vowel and the “ch” sound, then –ch is used.
Examples: scrunch, bunch, finch, bench, pinch, punch,
In order to be sure that the rule is learned, dictation with nonsense words can be given. Words like: splutch, quitch (remember: qu is considered a consonant, so the ui is NOT a vowel team in this instance), bletch
