Sliding Sound Teacher Guide Teacher Guide: The Sliding Sound
Lesson 1: Phonemic Awareness of /oi/
Objectives
Identify and isolate the /oi/ sound in spoken words.
Observe and describe the articulatory movement (mouth glide) for /oi/.
Distinguish /oi/ from other vowel sounds.
Materials
Small hand mirrors (one per student)
Picture cards: Boy, Toy, Coin, Oil, Boil, Soil
Distractor cards: Bat, Dog, Sun, Cat
The Hook
"Class, today we are going on a sound adventure! We are going to make a 'sliding sound.' Watch my mouth—it starts open like a circle and slides into a smile: /o/ -> /ee/ ... /oi/! Can you try that?"
Activity Steps
1
The Mirror Check
Hand out mirrors. Have students watch their lips. Ask: "Do your lips stay still, or do they move?" (They move/slide). Explain that /oi/ is two sounds sliding together.
2
Thumbs Up Treasure
Say a list of words. Students give a 'Thumbs Up' if they hear the /oi/ slide and a 'Thumbs Down' if they don't.
Words: Coin (Yes), Cat (No), Toy (Yes), Sun (No), Soil (Yes), Point (Yes), Big (No)
3
Sound Detective Hunt
Look around the room or use picture cards. "I spy something that makes an /oi/ sound and we play with it..." (Toy).
Teacher Tips & Differentiation
Scaffolding
Exaggerate the mouth movement. Have students touch their jaw to feel it move upward during the slide.
Extension
Ask students to count how many sounds they hear in "coin" (/k/ /oi/ /n/ = 3) or "boy" (/b/ /oi/ = 2).

Lesson 3: Decoding Final 'oy'
oy
Objectives
Identify that 'oy' is a digraph that makes the /oi/ sound.
Learn that 'oy' is typically found at the end of a word.
Decode and read words with final 'oy' in a gaming context.
The Spelling Rule
'oy' comes at the end of words.
Think: "Oh boy, a toy at the end!"
Lesson Flow
1
The Mystery Toy Box
Bring a box labeled "TOYS". Pull out picture cards of a boy, a toy, soy sauce, and a joy-filled face. Ask: "Where do you hear the /oi/ sound?" (The end).
2
The 'Y' Connection
Remind students that 'y' likes to be at the end of words (like 'my' or 'play'). This helps them remember that 'oy' is the end-of-word spelling for /oi/.
3
Blending Endings
Model blending words with only two sound boxes: b - oy, t - oy, s - oy.
Game: Toy Tag
Place 'oy' word cards around the room. When you call out a word, students must "tag" the word and shout the final sound "OY!"
Words: Boy, Joy, Toy, Soy, Roy, Troy, Coy.

Lesson 4: Comparative Sorting of 'oi' and 'oy'
Objectives
Apply the positional spelling rule to sort words into 'middle' and 'end' categories.
Explain the reasoning for choosing 'oi' vs 'oy' based on position.
Practice reading mixed 'oi' and 'oy' words accurately.
The Key Question
"Where is the sound?"
Middle = oi
End = oy
The Inquiry Hook
"Oh no! A pirate ship crashed and all the treasure is mixed up! Some of these treasures belong in the Coin Chest (Middle /oi/) and some belong in the Toy Box (End /oi/). How can we tell them apart?"
🪙
"I see a word 'Boil'. B-oi-l. Is the sound at the end?" (No). "So it goes in the..." (Coin Chest!)
🧸
"I see a word 'Joy'. J-oy. Is the sound at the end?" (Yes!). "So it goes in the..." (Toy Box!)
Discussion Questions
Rule Check:
"Why did we put 'point' in the middle chest even though it's near the end?" (Because the 't' is still after it!)
Visual Hint:
"What letter do we usually see at the very end of words that we also see in 'oy'?" (The letter Y!)
