The FLOSS Secret Rule
Unit 4 Core Standard
When do we give a letter its bonus twin?
Choral recite with me when you see the 3 golden keys:
1
1 Syllable
Just one chin drop! A short, snappy one-syllable word.
2
Short Vowel
Immediately after /ă/, /ĕ/, /ĭ/, /ŏ/, or /ŭ/.
3
Ends in f, l, s, z
Double it! Write ff, ll, ss, zz and add a star ⭐!
"One syllable, short vowel sound, double f, l, s, and z on the ground!"
I DO • Teacher Model Watch & Listen
Marking Routine
Target Word: "puff"
p
/p/
u
/ŭ/
f
/f/
⭐ f
silent twin
Teacher Think-Aloud:
- 1 syllable: "puff"
- Short vowel: /ŭ/ (u-up-/ŭ/)
- Ends in f: It must get a bonus letter f!
- Mark it: Put a small star ⭐ over the second f.
Anita Archer Rule: "Both letters make only ONE sound: /f/. The twin gives the short vowel protection!"
WE DO • Guided Tapping Together on Signal
Choral Response
Word 1: /b/ /ĕ/ /l/ 🔔
b /b/
e /ĕ/
l /l/
⭐ l bonus
1. Tap sounds: 3 taps (/b/ /ĕ/ /l/)
2. Spell check: Short /ĕ/ + ending /l/ = double ll!
Word 2: /m/ /ĭ/ /s/ 🎯
m /m/
i /ĭ/
s /s/
⭐ s bonus
1. Tap sounds: 3 taps (/m/ /ĭ/ /s/)
2. Spell check: Short /ĭ/ + ending /s/ = double ss!
Prompt: "Fingers up... Tap it... Spell it together!" How many taps? 3! How many letters? 4!

Word: buzz • Sound count: 3 sounds
🥤
f i z ⭐z
Word: fizz • Sound count: 3 sounds
Think time (2 sec)... Teacher drops hand... EVERYONE SAYS: "Short vowel, end in z, add bonus z!"
Detective Check Non-Examples & Rule Breakers
Why NO Bonus Letter?
Does every word ending in s or f get a bonus twin? NO! Look closely:
Intervention detectives check all 3 golden keys every time.
buss bus
Why only one 's'?
"Bus" and "gas" are rare sight exceptions. We memorize them with our visual memory!
leaff leaf
Why only one 'f'?
The vowel sound is long /ē/ (ea vowel team), NOT a short vowel!
helpp help
Why no bonus letter?
It ends in p, not f, l, s, or z! Only FLOSS letters double.
Anita Archer Tip: Always test: 1 syllable? Short vowel? Ends in f, l, s, z?

Teacher Error Analysis & Next Steps
| Observed Error | Root Cause Analysis | Targeted Intervention Action |
|---|
| Omits twin (*bel*, *cuf*) | Sound-to-letter 1:1 mapping reliance (only heard 1 sound). | Use 4-box Elkonin sound cards with pre-drawn star in box 4. |
| Doubles wrong letter (*help* → *helpp*) | Overgeneralized "double ending letter" without FLOSS limit. | Re-teach 4 specific FLOSS letters using tactile sorting cards. |
| Hesitant blending (>3 sec) | Weak vowel sound automaticity; pausing at the vowel. | Run 30-second rapid vowel sprint before decodable reading. |
