"But what about 'said' and 'was'? When do I teach those?"
This question comes up in every phonics training I lead. Teachers know they need to teach systematic patterns, but they also see kids struggling with high-frequency words that don't follow the rules they've been teaching.
It's the classic phonics dilemma: Do you stick to patterns and let kids struggle with exceptions? Or do you teach exceptions early and risk confusing the pattern learning?
The answer isn't either/or. It's strategic both/and.
The Pattern vs. Exception Balance
Here's what I've learned after years of trying to get this balance right: kids need a strong foundation in reliable patterns before they can handle exceptions gracefully. But they also need access to some irregular words for meaningful reading and writing.
The key is being strategic about which exceptions you teach when, and how you teach them.
The Exception Categories That Matter
Not all irregular words are created equal. Some are worth teaching early, others can wait:
Tier 1: Essential exceptions (teach early) Words kids need for basic reading and writing: the, was, said, come, some, one, two
Tier 2: Frequent exceptions (teach after solid pattern foundation) Common but not essential: their, where, what, who, been, does
Tier 3: Advanced exceptions (teach much later) Less frequent irregulars: colonel, yacht, debris, fatigue
The Strategic Teaching Approach
For essential exceptions: Teach them as "heart words" - words we learn by heart because they don't follow the patterns yet For patterns: Teach them systematically with lots of practice and application For frequent exceptions: Wait until kids have strong pattern foundations, then introduce strategically For advanced exceptions: Deal with them as they come up in reading, not through direct instruction
The Timing That Works
Here's the sequence I've found most effective:
Phase 1: Build pattern foundation Teach reliable CVC patterns, common consonant blends, short vowels Introduce 3-5 essential heart words for writing (the, was, said)
Phase 2: Expand patterns systematically Add digraphs, vowel teams, silent letters Gradually add more heart words as needed (come, some, one)
Phase 3: Handle exceptions strategically Once kids have solid decoding strategies, introduce exceptions as interesting variations rather than confusing contradictions
The Sofia Learning Journey
Sofia was a first-grader who got completely confused when her previous teacher tried to teach sight words and phonics patterns simultaneously. She'd see "come" and try to apply short vowel rules (/k/ /ŏ/ /m/), get frustrated when it didn't work, and start doubting all the patterns she'd been learning.
When Sofia came to my class, I took a different approach:
"Sofia, most words follow patterns that we can learn. But English has some special words that we learn by heart. We call them 'heart words.' Let's learn a few heart words that you need for writing, and then we'll focus on learning the patterns that work for most words."
I taught her 'the', 'was', and 'said' as heart words while we systematically built her pattern knowledge with decodable words. Once she had strong foundations, exceptions stopped being threatening and started being interesting.
The Heart Word Strategy
For essential exceptions, I use the "heart word" approach:
Step 1: Identify the regular parts Even irregular words often have some regular parts. In "said," the 's' and 'd' are regular.
Step 2: Highlight the tricky part "The part we need to remember by heart is the 'ai' that says /ĕ/ instead of /ā/."
Step 3: Practice the whole word "Let's practice reading and spelling the whole word: s-a-i-d, said."
Step 4: Use in meaningful context "Now let's use 'said' in sentences so we remember what it means."
The Pattern-First Philosophy
I'm convinced that teaching patterns first creates stronger readers than teaching exceptions first:
Pattern-first kids: Develop systematic strategies for unknown words, have confidence tackling unfamiliar text, understand that English makes sense at a deep level
Exception-first kids: Learn that reading is about memorization, develop weaker decoding strategies, approach unfamiliar words with anxiety
The Assessment That Guides Decisions
How do you know when kids are ready for more exceptions?
Pattern mastery check: Can they decode unfamiliar words using known patterns? Exception handling: When they encounter an irregular word, do they try patterns first, then ask for help? Confidence level: Do they approach unknown words with strategies or with anxiety? Transfer ability: Can they apply pattern knowledge to new situations?
Common Teaching Mistakes
Mistake 1: Teaching too many exceptions too early This confuses the pattern learning that needs to happen first.
Mistake 2: Avoiding exceptions completely Kids need some irregular words for meaningful reading and writing.
Mistake 3: Not explaining the difference Kids need to understand that most words follow patterns, but some need to be learned differently.
Mistake 4: Making exceptions seem scary Frame exceptions as interesting variations, not threats to the system.
The Gradual Release Strategy
Week 1-8: Focus heavily on patterns, introduce 2-3 essential heart words Week 9-16: Continue pattern building, add heart words as needed for writing Week 17-24: Strong pattern foundation allows for more exceptions without confusion Week 25+: Kids can handle exceptions as interesting variations on the system they understand
The Writing Connection
The need for exceptions often comes up in writing first:
Kids want to write: "I said I was going to come." Without heart words, they might write: "I sed I wus goeng to kum."
Teaching a few essential irregular words allows for more authentic writing while pattern learning continues.
The Multilingual Learner Consideration
For kids learning English as an additional language:
Start with even fewer exceptions: Focus more heavily on patterns initially Explain the concept explicitly: Some languages have more consistent spelling - explain that English borrowed from many languages Use home language comparisons: If their language has irregular words, connect to that experience
The Advanced Reader Challenge
Advanced readers sometimes get bored with systematic phonics because they can already read many words. For these kids:
Challenge them with advanced patterns: Complex vowel teams, morphology, etymology Use exceptions as investigation opportunities: Why is "colonel" spelled that way? Accelerate the timeline: Move through patterns more quickly but don't skip the foundation
The Long-Term Vision
Kids with strong pattern foundations and strategic exception knowledge become:
Confident decoders: They have strategies for unknown words Flexible readers: They can handle both regular and irregular words Strategic spellers: They know when to use patterns and when to memorize Curious learners: They're interested in why English works the way it does
What This Means for Your Teaching
Don't choose between patterns and exceptions - choose strategic timing for both.
Build strong pattern foundations first, then gradually introduce exceptions as variations rather than violations.
Teach essential irregular words as "heart words" that we learn differently from pattern words.
Help kids understand that most English words follow patterns, making the language learnable and systematic.
Frame exceptions as interesting rather than threatening.
The Strategic Balance
The art of phonics instruction isn't about perfect adherence to patterns or complete avoidance of exceptions. It's about strategic timing that builds both systematic decoding skills and flexible word recognition.
When kids have strong pattern foundations, exceptions become interesting variations rather than confusing contradictions.
The strategy makes all the difference.
