Teaching spelling rules is essential because while many concepts may be predictable for reading, they can be irregular for spelling. One crucial rule that often trips up young learners is the Floss Rule. Understanding this rule can improve both spelling accuracy and reading fluency.
The Floss Rule states that when a one-syllable word ends in f, l, s, or z after a short vowel, the final consonant is doubled. For example, words like puff, bell, pass, and fizz follow this rule. However, it’s important to note that some words break the rule, and these exceptions must be explicitly taught (e.g., was, has, gas).
Three Checkpoints for the Floss Rule
To determine if a word follows the Floss Rule, ask yourself these three questions:
-
Is the word one syllable?
-
Does the word end in the letters f, l, s, or z?
-
Does the word have one short vowel?
If the answer is “yes” to all three, the final consonant should be doubled!
Essential Pre-Teaching Concepts
Before introducing the Floss Rule, ensure students have a strong foundation in:
-
Short vs. long vowel sounds
-
The difference between vowels and consonants
Additionally, for students with speech sound disorders, be mindful that they may attempt to pronounce the doubled consonant twice (e.g., /f/ /f/ in puff). Remind them that in English spelling, a doubled consonant is written but only pronounced once.
