Lesson Objectives

By the end of this 30-minute lesson, students will be able to:

2. Practice decoding strategies for unfamiliar words with "oi."
3. Use the identified words in simple sentences to reinforce comprehension.

Lesson Plan: Irregular Vowel "OI"

---

Materials Needed

• Flashcards with "oi" words (boil, coin, soil, foil, join, etc.)
• Magnetic letters or letter tiles
• A short story or poem with multiple "oi" words (teacher-created or provided).
• Whiteboard and markers
• Paper and pencils

---

Lesson Breakdown

1. Warm-Up (5 minutes)

• Start with a mystery sound game: Write “oi” on the board, and make the sound it represents /oi/. Ask students to repeat the sound while holding their hands around their mouths like a megaphone.
• Provide two examples: "coin" and "boil," and ask students to stretch out the sounds: c-oi-n, b-oi-l.
• Quick brainstorming: Can anyone think of other words with the "oi" sound? Write these on the board.

---

2. Direct Instruction (5 minutes)

1. Explain that some vowel combinations don’t follow usual rules, like "oi."
   • When "o" and "i" work together, they make the /oi/ sound.
   • Give examples: boil, join, foil, soil.
2. Show flashcards with "oi" words. Say each word, have students repeat, and briefly discuss the meaning of any unknown words.
3. Break down a sample word (“coin”) on the board:
   • Ask: “What vowel team do we see in this word?” [Students should respond “oi.”]
   • Blend the word aloud as a group: /c/ - /oi/ - /n/.

---

3. Hands-On Activity (10 minutes)

Option 1: Build-a-Word

• Use magnetic letters or letter tiles. Place the letters “o” and “i” together as a base.
• Challenge students to create new “oi” words by adding different consonants (e.g., “j” to make join, or “f” to make foil).

Option 2: Roll and Write

• Give each student a die. Write a word starter on the board, such as "s-" or "b-," and let students take turns rolling the die to complete the word using "oi." For example:
  • Roll 1 = Coin
  • Roll 2 = Soil
  • Roll 3 = Join (and so forth).

---

4. Reading in Context (5 minutes)

• Distribute the short story or poem that features "oi" words. Read it aloud as a group.
• Students circle all the "oi" words they hear or see. Compare findings together after reading.

Example Excerpt:
"Roy found a shiny coin in the soil while he boiled some water for tea!"

Discuss:

• What is Roy doing? Where did he find the coin?

---

5. Closing and Assessment (5 minutes)

• Have each student choose one “oi” word from the lesson and use it in their own sentence. Allow each student to share their sentence with the class.
• Write a group sentence on the board using as many "oi" words as possible to wrap up.

---

Extension/Challenge Activity:

If time permits, let the students pretend they’re pirates searching for treasure. Each “oi” word represents a clue to the location of the treasure. For example:

• Clue 1: It’s hidden in dark soil!
• Clue 2: You can use foil to reveal it!

---

Teacher Tips

• Be animated when teaching the sound /oi/. Exaggerate the pronunciation to make phonics fun.
• Provide differentiation by adjusting the complexity of "oi" words (e.g., using simpler words like “coin” for struggling readers, and complex examples such as “rejoice” for advanced learners).

---

Irregular Vowel "OY"

---

Follow a similar structure to the "oi" lesson, explaining the sound /oi/ as represented by the "oy" vowel team. Adapt activities slightly (e.g., focus on words like toy, joy, boy, enjoy).

---

Irregular Vowel "OU"

---

Teach the /ow/ sound of "ou" using examples like loud, cloud, shout, and round. Include activities tailored to this combo.

---

Irregular Vowel "AU"

---

For "au" (making the /aw/ sound), focus on words like cause, pause, fault, and launch. Use the same structure but with new engaging materials.
