Lesson 9: Complex Patterns 1 - Diphthongs & Alternative Spellings
🎯 Learning Objectives
🧭 Pattern Spotter Sort (7 mins)
Live/local protocol: Complex spellings are learned by contrast, not by rule-recitation. Sort first, name the pattern second.
- Before: Put twelve words carrying the target patterns face-up (catch, badge, city, cage, patch, ridge). Do not name the rule yet.
- During: Ākonga sort into groups that feel alike and say what the groups have in common. Accept any consistent sort, then steer toward the sound-and-position pattern: -tch and -dge come straight after a short vowel.
- Kaiako move: Ask for the odd one out and why (rich, much). Naming an exception is stronger evidence of understanding than reciting the rule.
- After: Each ākonga writes the pattern in their own words plus one word that proves it, and one that breaks it if they found one.
- Immediate Use: Keep the sorted groups on the desk during the writing task so the pattern stays visible while spelling.
- Support / Stretch: Support by pre-sorting into two groups and asking only for the difference. Stretch by predicting the spelling of an unseen word from its vowel sound, then checking.
- Students understand that some vowel sounds are made by two vowels gliding together (diphthongs)
- Students can identify and read words with oi/oy and ou/ow patterns
- Students recognise alternative spellings for the same sound
- Students apply knowledge of complex patterns to decode unfamiliar words
- Students understand that English has multiple ways to spell the same sound
📦 Materials Needed
Teacher Materials:
- 'The Code' diphthong cards (oi, oy, ou, ow)
- Sound comparison charts
- Picture cards for diphthong words
- Whiteboard and coloured markers
- Alternative spelling reference sheets
Student Materials:
- Individual diphthong cards
- Word sorting mats
- Spelling choice worksheets
- Pencils and erasers
- Small whiteboards and markers
1. Warm-Up: Vowel Sound Journey (6 mins)
Teacher Script: "We've learned about vowel sounds that stay in one place. Today we'll discover vowel sounds that take a journey - they start in one place and glide to another!"
Sound Journey Demonstration:
- Listen: Say "boy" slowly - notice how the sound moves from /o/ to /i/
- Listen: Say "cow" slowly - notice how it moves from /a/ to /oo/
- Movement: Use hand gestures to show the gliding motion
- Discovery: "These are called diphthongs - sounds that glide!"
2. Teaching oi/oy Diphthong (10 mins)
Systematic Introduction: Teach the /oi/ sound with its two common spellings.
oi spelling:
- Sound: /oi/ (like in "oil")
- Position: Usually in the middle of words
- Words: oil, coin, point, join
- Memory: "oi in the middle"
oy spelling:
- Sound: /oi/ (like in "boy")
- Position: Usually at the end of words
- Words: boy, toy, joy, enjoy
- Memory: "oy at the end"
Teaching Process:
- Teach the /oi/ sound first (without spelling)
- Show that this sound has two different spellings
- Teach the position pattern (oi middle, oy end)
- Practice with examples and exceptions
- Apply to reading and spelling new words
3. Teaching ou/ow Diphthong (12 mins)
Second Diphthong: Introduce the /ou/ sound with its spelling variations.
ou spelling:
- Sound: /ou/ (like in "out")
- Position: Usually in the middle of words
- Words: out, house, about, count
- Memory: "ou in the middle"
ow spelling:
- Sound: /ou/ (like in "cow")
- Position: Usually at the end of words
- Words: cow, how, now, brown
- Memory: "ow at the end"
Important Note About 'ow':
Challenge: 'ow' can make two different sounds!
- /ou/ sound: cow, how, now (diphthong)
- /ō/ sound: snow, grow, show (long o)
- Strategy: Try both sounds to see which makes sense
4. Spelling Choice Practice (12 mins)
Decision Making: Students practise choosing the correct spelling for diphthong sounds.
Spelling Choice Activities:
oi or oy?
- b___ (boy/boi) → boy
- c___n (coin/coyn) → coin
- t___ (toy/toi) → toy
- p___nt (point/poynt) → point
ou or ow?
- c___ (cow/cou) → cow
- h___se (house/howse) → house
- n___ (now/nou) → now
- ab___t (about/abowt) → about
5. Independent Practice & Exit Ticket (5 mins)
Exit Ticket Task
"Read these words: 'enjoy', 'sound', 'brown'. Then write the correct spelling for these sounds: /oi/ at the end of a word, /ou/ in the middle of a word."
Success Criteria:
- Emerging: Reads most diphthong words correctly, identifies some spelling patterns
- Developing: Reads all words correctly and applies position rules accurately
- Secure: Demonstrates confident understanding of diphthongs and spelling choices
📊 Assessment & Differentiation
Formative Assessment:
- Observe diphthong sound production
- Check spelling pattern recognition
- Monitor position rule application
- Assess decoding of new diphthong words
Support Strategies:
- Struggling: Focus on one diphthong at a time, use gesture cues
- Confident: Introduce au/aw patterns, explore exceptions
- ELL Support: Compare to diphthong sounds in home language
Kaiako Planning Snapshot
English Literacy — Structured Literacy & Phonics Foundations — Years 7–8
Te Mātaiaho (2025 draft) | English — Years 7–8. This snapshot records Lesson 9's teaching focus; the unit overview carries the curriculum anchor.
Ngā Whāinga Akoranga — Learning Intentions
- Recognise alternative spellings for the same sound, including -tch and -dge
- Sort words by sound and spelling pattern
- Justify which spelling fits where a sound sits in a word
Differentiation & Proximal Guidance
Entry: pre-decodable word cards with visual supports and phoneme frames. On-level: target word list with blending practice. Extension: student-generated sentences using target pattern in context.
Cultural context: tikanga-based classroom protocols (karakia, mihimihi, manaakitanga) frame each session. Incorporate te reo Māori alongside structured literacy to honour hauora and whanaungatanga.
