Teaching Double Consonants “ff”

Phonics, Spelling, & Grammar Resources

Teaching spelling and phonics can be challenging, especially when it comes to Teaching Double Consonants “ff” Rules. However, understanding this rule is crucial for students to develop strong spelling skills. In this comprehensive guide, we’ll explore the ins and outs of the double “FF” consonant rule, provide examples, and address common issues and confusions students may encounter. You’ll also find a stack of fun and engaging resources to help your learners master double consonants as well as handy hints and info for Teaching Double Consonants.

The Double “ff” Consonant Rule FLOSS Rule

Using spelling rules is a great way for students to learn when to use double letters in their spelling and writing and there are two to teach them about when and how to use double “ff” in words; the FLOSS Rule and the Double Consonant ‘ff’ Rule.

Knowing when to use double “ff” at the end of a word comes down to understanding certain spelling rules and one of these rules is the FLOSS Rule.

The FLOSS Rule is a mnemonic used to remember when to double the final consonant at the end of one-syllable words after a short vowel sound.

which says that in one-syllable words, if a vowel is immediately followed by “f,” “l,” “s,” or sometimes “z,” you double the final consonant. This helps keep the vowel short and the pronunciation clear.

For example, in the word “fluff,” we double the “f” because the vowel “u” is immediately followed by “f.” Without the double “f,” the word would be pronounced differently. So, the double “ff” helps us spell words in a way that matches their pronunciation and keeps things consistent in English spelling.

So now let’s talk about the Final Double “ff” Consonant Rule. It’s pretty straightforward, actually. If you’ve got a word that already ends in a double “ff” and you want to add on something like “-ed” or “-ing,” you don’t need to change a thing!

For example, let’s take the word “puff,” if we want to say “puffed” or “puffing,” we still keep that double “ff,” giving us “puffed” and “puffing.”

Common Issues and Confusions


Despite the straightforward rule, students may encounter some issues and confusion when learning about the double “ff” consonant rule. Let’s address them:

1. Overgeneralisation:

  • Issue: Students may incorrectly apply the rule to words where the final syllable is not stressed, leading to misspellings.
  • Solution: Provide ample practice opportunities and emphasize the importance of recognising stress patterns in words before applying the rule.

2. Lack of Phonemic Awareness:

  • Issue: Students may struggle to identify short vowel sounds, leading to difficulties in determining when to double the “F.”
  • Solution: Incorporate phonics activities and exercises focused on short vowel sounds to improve students’ phonemic awareness.

3. Memorisation of Exceptions:

  • Issue: Students may find it challenging to memorise exceptions to the rule, such as words where the final syllable is stressed but the “F” is not doubled.
  • Solution: Highlight common exceptions like “belief,” “chef,” and “calf,” and provide mnemonic devices or word association techniques to aid memorization.

By understanding the rules, providing examples, and addressing common issues and confusions students will develop strong spelling skills.
