Objective

By the end of this lesson, students will:

1. Identify words that contain initial, middle, and final consonant digraphs (e.g., ch, sh, th, wh, ck, ng).
2. Accurately pronounce and fluently read words with consonant digraphs in isolation and in simple sentences.
3. Apply phonics knowledge to sort digraph words based on their positions in a word (initial, middle, final).

Materials Needed

• Flashcards with consonant digraphs (ch, sh, th, wh, ck, ng).
• Word cards (examples include: chair, shell, thick, bath, whisk, brick, king).
• A small whiteboard or chart paper and markers.
• A printable "Digraph Detectives" worksheet for sorting words.
• A small bucket labeled “Digraph Treasure Chest.”
• Magnetic letter tiles or movable letter cards.
• A short story with target consonant digraphs embedded in it (teacher-created or pre-existing).

Lesson Outline

Introduction (5 Minutes)

1. Hook Activity:

   • Say: "Today, we’re going on a fun adventure to crack the secret code of some tricky sounds that make ONE sound together. They’re called digraphs!"
   • Display a treasure chest on the board with a mix of digraphs (ch, sh, th, wh, ck, ng) scattered around it, visually resembling clues for the students to solve.

2. Interactive Demonstration:

   • Write the word “chair” on the board.
   • Say: "The letters c and h are buddies! Together, they make the /ch/ sound. What happens if we separate them?"
   • Erase one of the letters and ask, "Does it still sound the same?"
   • Conclude: "When certain letters work together, they make a new sound. That’s a digraph!"

Instruction & Guided Practice (12 Minutes)

1. Digraph Introduction (5 Minutes)

• On the whiteboard, write and introduce the target consonant digraphs in three categories:

  • Initial Position: ch-, sh-, wh-, th- (show, chair, where, think).
  • Middle Position: Words such as chicken, wishes, thicker, whiskers.
  • Final Position: -ck, -ng, -ch, -sh, -th (kick, king, beach, dish, bath).

• Emphasize their blended sounds through loud and clear enunciation. For example: “Listen to the /sh/ in shell – shhhhh, like you’re telling someone to be quiet!”

2. Team Practice (7 Minutes)

• Activity: "Digraph Treasure Chest"

  • Each child takes turns drawing a word card (examples: chop, wish, thick, whisk, kick, bang).
  • They place their card in the “treasure chest” labeled with the appropriate digraph position (either initial, middle, or final).
  • Encourage students to say the word aloud and emphasize the digraph sound clearly.

• Follow-Up Question: Ask, “What would happen if the digraph wasn’t in the treasure chest? Would the word still sound the same?”

Independent Practice (8 Minutes)

1. "Digraph Detectives" Worksheet

   • Students receive a worksheet where they sort 12 words into categories: Initial Digraph, Middle Digraph, and Final Digraph.
   • Example answers on the worksheet:
     • Initial: whale, think, chair.
     • Middle: chicken, wishes, quicker.
     • Final: shock, bring, dish.

2. Sentence Reading Challenge

   • Prepare a short story with lots of digraphs. Example:
     "Chip the Chick was wishing for a shiny shell. He sang a long song to thank his friend, King Chuck."
   • Each student takes turns reading a sentence aloud while the group identifies the digraphs in the sentence.

Wrap-Up & Assessment (5 Minutes)

1. Quick Quiz Game: “Odd Sound Out”

   • Say a sequence of words aloud (e.g., shop, ship, sing, shape). Ask the students to identify the word with a different digraph and explain why.
   • Example Answer: sing has the /ng/ sound, while the others have the /sh/ sound.

2. Reflection Question (Each student shares aloud):

   • “What’s one new word you learned today that has a digraph? Which digraph is it?”

3. Praise the students for being “Digraph Detectives” and invite them to use one new digraph word at home tonight or in writing tomorrow.

---

Assessment

• Formative: Observe students during the treasure chest and sorting activity to check understanding of initial, middle, and final digraph placement.
• Worksheet completion and sentence-reading fluency will serve as additional checks for comprehension and application.

---

Differentiation

For Advanced Learners:

• Provide a challenge activity to write a short story using at least three target digraphs.

For Struggling Learners:

• Offer one-on-one guidance during the treasure chest activity. Focus on two digraphs (ch and sh) first, before introducing the others. Use more visual supports like diagrams or videos showing sounds visually through mouth movements.

---

Homework

• Encourage students to play “word detective” at home. Their mission: Find five objects in their house or outside that have a digraph in their name. Write the word and circle the digraph.

Teaching Tip

Use exaggerated articulation when pronouncing digraphs to make the sounds clear and memorable. Keep the tone playful and encourage curiosity by framing the activities as detective work or treasure hunts, which can make phonics practice fun and engaging for second graders!
