Sound Sack Teacher Guide Teacher Resource • Lesson 1 Guide
Sound Sack Facilitation
2nd Grade Phonics
/oi/ and /oy/ Discovery
Objective
Students will isolate and identify the /oi/ phoneme in various word positions through auditory discrimination.
Duration
45 Minutes (15 Hook, 10 Practice, 20 Independent Sort)
Prep
Opaque sack/bag, objects: coin, toy, foil, boy doll (or pictures).
1
The Hook: Mystery Sound Sack (15 min)
Action: Gather students on the rug. Hold up your "Sound Sack." Pull out one object at a time and have students name it chorally.
"Class, I have some secret items in my sack. Let's see what they are! (Pull out coin) What's this? A coin ! (Pull out toy) And this? A toy ! Listen to those words: c-oi-n, t-oy. What's the secret sound they share?"
Key Point: Explain that /oi/ is a diphthong (a gliding sound). Your mouth starts open and circles to a smile.
2
Guided Practice: Thumbs Up! (10 min)
Say a list of words. Students give a Thumbs Up if they hear /oi/ and a Thumbs Down if they don't.
Boil (Yes)
Enjoy (Yes)
Boat (No - /ō/)
Point (Yes)
Cow (No - /ow/)
Oyster (Yes)
Detective Tips (Differentiation)
Scaffolding
Have students touch their throat as they say /oi/ to feel the vibration. Use a mirror so they can see their mouth "glide" from a round O to a small smile.
Extension
Ask students to count how many phonemes (sounds) are in words like oil (2) or point (4). This builds deeper phonemic awareness.

Roy is a boy who likes to sail. One day, Roy saw a big buoy in the bay. He wanted to go on a voyage. Roy put some oil in his small boat. He did not want the boat to make a bad noise.
The sun was hot. Roy felt great joy as he sailed. He saw a shiny gold coin in the soil near the shore. "I must point this out to my dad!" Roy said. He used a piece of foil to wrap the coin. Roy was a loyal friend and shared his find. It was a wonderful day for a boy like Roy.
