98% of words in English follow 31 phonogram and spelling rules and there’s one in the bunch that gets kids AND their dentists excited: the Floss Rule!

It’s a handy little trick that explains why some letters need to be doubled like F in the word PUFF and S in the word MISS.

And thanks to its playful name, not only is the rule fun to learn, it also helps beginning readers successfully sound out words.

So what’s the Floss Rule?

When the letters F, L, S, and Z appear after a short vowel in one syllable words, they get doubled.

You can try it out with words like hill, doll, ill, yell, and of course… FLOSS.

Once you learn it, you’ll start seeing it EVERYWHERE. 

Your students can truthfully say they “floss” every day!

IMPORTANT NOTE: As with any spelling rule, it’s important to mention that there will be some exceptions including some words that end in s, but have a sound (his, has, and is) and any plural words that end in s (boys, dogs, and wigs).

But just like finding Floss Rule words is fun, so is discovering all of the exceptions!
