Today’s topic is FLOSS, and I’m not talking about teeth here. FLOSS is a helpful reminder to a short vowel rule that says: double f, l and s after a short vowel at the end of a ONE SYLLABLE word. This concept is taught in mainstream methods, but calling it FLOSS is something done in OG.
Seen here is a whole list of words from a book, How to Teach Spelling.
As in most rules, there are exceptions to the FLOSS rule.
First, when a final s makes the “z” sound it is never doubled, Examples: is, as, has, was, his
These words do NOT double, but if we were following the rule, they would.
Examples: Bus, gas, plus, if, chef, gal
And, some words double but they should NOT.
Examples: egg, odd, add, err, shirr
Some proper names ending in consonants will double.
Examples: Matt, Todd, Squibb
See the worksheet example here for a great representation of the FLOSS rule. As you can tell, the O in FLOSS is just there to create the word to help to remember the other three letters.
Here is another worksheet example on FLOSS that gives dictation and examples.
Another letter that doubles after a short vowel in a one syllable word in most cases is z.
Now, about your teeth, have you FLOSSed lately?
