Sound Isolation Challenge
Close your eyes and listen. Focus entirely on the phoneme sounds!
1 Target Sound Detection
Listen to these words: knot, knee, know.
Teacher Prompt:
"What is the very first sound you hear in these words?"
Answer: /n/
2 Phoneme Manipulation
Say wrap (/r/ - /æ/ - /p/)
Swap the /r/ to /n/
What word is it? → nap
Keep ears sharp—letters can be tricky! Slide 3 of 14

The Mystery of the Silent Partners
Sometimes two consonant letters team up, but only one of them makes a sound!
k/ n
/n/
The k stands silently in front. The n speaks clearly!
w/ r
/r/
The w stands silently in front. The r speaks clearly!
g/ n
/n/
The g stands silently in front. The n speaks clearly!
Why do we write them? History! They used to have sounds long ago. Slide 5 of 14

The Spelling Rule
We use kn at the beginning of base words to make the sound /n/.

The Spelling Rule
We use wr at the beginning of words when the word is about bending, twisting, or hand/writing action!
Read Aloud Challenge: Identify silent guards
wrap
wreck

wrist
To twist or turn is 'wr' (like wrestle, wrap, and wreath)! Slide 7 of 14

The Spelling Rule
We use gn to spell /n/. Unlike kn, gn can be found at the beginning OR the end of words!

A tiny 'gnat' is gnawing on a tree—both have silent 'g'! Slide 8 of 14

| Time | Step / Module | Core Teacher Action & Script Prompt |
|---|
| 5 Mins | Auditory Drill | Warm up ears! Do sound manipulation. Say "wrap". Swap /r/ for /n/. What is the new word? ("nap"). |
| 5 Mins | Rapid Naming | Run slide 4. Point to phonics card boxes. Students say sounds /n/, /r/, /n/ rapidly with automatic retrieval. |
| 10 Mins | Concept Cards | Explicitly introduce the 3 silent letters. Explain the "Silent Guard Partner" concept. Point out that these digraphs contain a silent first letter and are found at word starts (except gn). |
| 10 Mins | Sound Mapping | Model sound isolation on slide 9 (knight). Guide students to tap 3 beats: /n/-/ī/-/t/. Fill in the Elkonin boxes on Worksheet Page 1. |
Step 1 Instruction Script (Auditory Drills)
Teacher Script Prompt:
"Sleuths, look at me and close your eyes. Listen to these three words: knee, knock, know. What is the very first sound you hear in all three? Yes, /n/! Today we are learning how to spell that /n/ sound when there is a silent partner letter standing guard in front."
Expected behavior: Students echo words, tap fingers for each phonetic beat, and identify isolating phonemes.
