Grade Level: 3rd Grade

Duration: 50 minutes

Students: 1

Subject: English Language Arts (ELA)

Common Core Standards Focus:

• CCSS.ELA-LITERACY.RF.3.3.C: Decode multisyllable words with common prefixes and suffixes.
• CCSS.ELA-LITERACY.RF.3.3.D: Decode words with common Latin suffixes.

Learning Objectives

By the end of this lesson, the student will be able to:

1. Recognize and apply the CK spelling rule correctly in words when the sound /k/ occurs immediately after a short vowel sound.
2. Identify and correctly spell words containing digraphs ("sh," "ch," "th," "wh") in isolation and in sentences.
3. Decode and encode (spell) words using knowledge of the CK rule and digraphs to build fluency and spelling accuracy.

Materials Needed

• Whiteboard and markers
• Letter tiles or magnetic letters
• Word cards featuring CK words and digraph words
• Notebook (for written practice)
• Timer
• Flashcards with images corresponding to digraphs and CK words
• Small dry-erase board and marker (for student use)

Lesson Structure

1. Warm-Up & Review (5 minutes)

Objective: Activate prior phonics knowledge and introduce the focus for today.

• Begin by briefly reviewing short vowel sounds with the student.
• Quickly recap what a digraph is using simple examples (e.g., "sh," "ch," "th," "wh").
• Introduce the CK spelling rule: Explain that when you hear the /k/ sound right after a short vowel, you often spell the sound with "ck" instead of "k."
• Show examples: "back," "sock," "duck," and contrast with "bake," "bike" (single k at end after a long vowel).

---

2. Explicit Instruction (10 minutes)

Objective: Teach the CK rule and reinforce digraphs through teacher modeling and student participation.

• Write examples on the board of words that use “ck” after a short vowel sound: “pack,” “rock,” “sick.” Explain the rule explicitly.
• Show common digraphs: sh, ch, th, wh. Pronounce each one clearly and have the student repeat.
• Demonstrate how to segment these words by sounds (phonemes) and blend them together.
• Use letter tiles to build words such as "chip," "shell," "that," and "whip."
• Have the student build several words with the CK pattern and digraphs on their mini whiteboard.

---

3. Guided Practice (15 minutes)

Objective: Apply CK spelling rule and digraph knowledge with scaffolding.

• Present the student with a list of 10 words (5 CK words, 5 digraph words). Examples:
  • CK words: pack, lock, duck, sock, sick
  • Digraph words: ship, chin, thin, when, what
• Read each word aloud and have the student clap out the syllables and sounds.
• Student writes each word, emphasizing correct placement of "ck" or correct digraph letter combinations.
• Use flashcards with images to prompt the student to spell the corresponding word aloud and write it down.
• Have the student explain why “ck” is used in each CK word (answer: comes after short vowel sounds).

---

4. Independent Practice (12 minutes)

Objective: Strengthen mastery by using words in context.

• Provide 5 fill-in-the-blank sentences that require the student to write CK or digraph words from the practiced list. Example:
  • The ___ (duck) swims in the pond.
  • She will ___ (whip) cream for the dessert.
  • I lost my ___ (sock) in the laundry.
  • The cat likes to ___ (chase) mice.
  • He had a ___ (thin) slice of pizza.
• Have the student read the completed sentences aloud for fluency practice.
• Encourage self-correction and explain reasoning for each spelling choice where needed.

---

5. Assessment & Wrap-Up (8 minutes)

Objective: Check for understanding and solidify learning.

• Oral Spelling Test: Say 10 words (5 CK + 5 digraph). Have the student spell each aloud and write it on a mini whiteboard or notebook.
• Error patterns are briefly reviewed to clarify misconceptions.
• Close the lesson by summarizing the CK rule and digraph sounds.
• Challenge the student: Ask them to think of one new word with "ck" and one with a digraph for next time.

---

Adaptations & Extensions

• For extra challenge, incorporate multisyllabic CK and digraph words (e.g., “backpack,” “whistle”).
• Use phoneme manipulation games: swap digraph sounds with other consonants to form new words.
• Use a recording device to let the student hear their reading and spelling, promoting self-assessment.

---

Reflection Notes for Teacher

• Monitor student’s ability to apply the rule without prompting.
• Use visual and tactile aids (letter tiles, flashcards) liberally for engagement.
• Encourage verbalization of thinking to deepen phonological awareness.
• Celebrate successes with positive reinforcement and occasional movement breaks if needed.
