Teaching Kids to Read? Start with Their Age, Not the Alphabet

Index of English Lessons

<<< Previous Chapter    Next Chapter >>>

When we think about teaching reading, we usually start with letters.

A. B. C.

But children don’t start with letters.

They start with sounds.

And more importantly — they start with different sound skills at different ages.

If you’re building a phonics app, designing a curriculum, or even just teaching your own child at home, understanding developmental milestones changes everything.

Let’s walk through what typically happens between ages 3 and 7 — and why rushing ahead often backfires.

---

Age 3–4: Recognize Rhymes

At this age, children aren’t ready to read.

But they are ready to hear patterns.

If you say:

“Cat… hat…”

They might giggle.

If you ask:

“Do cat and hat sound the same at the end?”

They can often tell you yes — even if they don’t know what a vowel is.

That’s because rhyming is about listening, not reading.

This is called phonological awareness — the ability to hear sound patterns in spoken language.

And it is the foundation of everything.

At 3–4, the goal isn’t spelling.
It isn’t blending.
It isn’t decoding.

It’s simply:

• Hearing similar endings

• Enjoying silly rhymes

• Playing with sound patterns

Songs, nursery rhymes, playful word swaps — these are powerful at this stage.

If you push reading too early here, you skip the listening stage. And when listening isn’t strong, decoding later becomes harder.

---

Age 4–5: Identify Beginning Sounds

Now the child starts noticing something new.

Not just that “cat” and “hat” rhyme…

But that:

Cat starts with “c”
Dog starts with “d”

This is the beginning of phonemic awareness — the ability to isolate individual sounds.

If you ask:

“What sound does ‘bat’ start with?”

They can begin to answer:

“Buh.”

Notice something important:

We focus on the sound — not the letter name.

Not “bee.”

But “buh.”

At this stage, children start connecting:

Sound → Symbol.

But only lightly.

This is not the stage for reading books independently.

This is the stage for:

• Sorting pictures by first sound

• Playing “I spy something that starts with mmm…”

• Matching sounds to letters casually

It’s discovery, not mastery.

And this is where many parents accidentally create frustration.

They see recognition of letters and assume readiness for reading.

But identifying a beginning sound is very different from blending sounds together.

---

Age 5–6: Blend CVC Words

This is the big leap.

This is where reading actually begins.

Now the child can take:

b – a – t

And blend it:

bat.

This skill — blending — is the core engine of decoding.

Without blending, reading becomes memorization.

With blending, reading becomes mechanical and repeatable.

At this stage, CVC words (consonant-vowel-consonant) are ideal:

cat
dog
map
sun
hat

They are clean, predictable, and phonetically regular.

This is also where confidence can skyrocket — or crash.

If you give a child blends (like “br” or “st”) too early, they may struggle.

If you give them irregular sight words too early, they may start guessing.

But if you stay with simple CVC patterns until blending feels automatic, something magical happens:

They realize reading is solvable.

It’s not magic.
It’s not memorization.
It’s sound logic.

And that realization builds confidence.

---

Age 6–7: Decode Independently

Now we move from “learning to read” to “reading to learn.”

By this stage, a child should be able to:

• Blend smoothly

• Recognize common patterns

• Decode unfamiliar CVC words

• Start handling blends and digraphs

They don’t need to memorize every word anymore.

They can attack new ones.

They see:

ship
thin
crab
brisk

And instead of freezing, they try.

That’s decoding independence.

This is also when reading fluency starts to matter.

Not just correctness — but smoothness.

Because now the brain has freed up enough energy from decoding to begin understanding meaning.

And that’s the true goal of reading.

---

Why This Progression Matters

When we skip steps, we create fragile readers.

For example:

Teaching sight words heavily at age 4 may create early performance — but weak decoding.

Pushing long vowel rules before short vowel mastery creates confusion.

Expecting independent reading before blending feels automatic creates anxiety.

But when the sequence matches development:

• Age 3–4 → Enjoy sound

• Age 4–5 → Notice sound

• Age 5–6 → Blend sound

• Age 6–7 → Decode confidently

The process feels natural.

Not forced.

---

If You’re Designing a Phonics App

This timeline should shape your features.

For 3–4:
Make it rhyme-heavy. Audio-first. Playful.

For 4–5:
Focus on beginning sound identification. Tap-the-picture games.

For 5–6:
Design blending animations. Word-building tools.

For 6–7:
Introduce decodable stories and fluency tracking.

The biggest mistake in EdTech is designing for a “generic child.”

Development matters.

Sequence matters.

And respecting cognitive readiness builds confidence instead of pressure.

---

Reading isn’t just about letters on a page.

It’s about wiring the brain in stages.

And when we match instruction to development, children don’t just learn to read.

They feel capable while doing it.

And that confidence — more than any word list — is what truly changes their future.

Building a Phonics App? Think in Levels, Not Words

Index of English Lessons

<<< Previous Chapter    Next Chapter >>>

When we teach a child to read, we often make one big mistake.

We teach words.

But children don’t learn reading word-by-word.
They learn it pattern-by-pattern.

If you’re building a phonics-focused SPA (or any early literacy product), the most powerful thing you can do is structure it as a progressive roadmap of sound mastery.

Here’s a simple, powerful 5-level framework that mirrors how children’s brains naturally develop reading ability.

---

🟢 Level 1 – CVC Words (cat, bat, map, pan)

This is where everything begins.

CVC stands for:

Consonant – Vowel – Consonant

Examples:

• cat

• bat

• hat

• pan

• map

• tap

Why start here?

Because CVC words are predictable. Clean. Decodable.

They teach a child the most important reading skill of all:

Blending sounds.

b + a + t → bat

This is where the brain first realizes:

“Oh… reading is just sounds joined together.”

Within this level, you group by word families:

• -at

• -an

• -ap

• -og

• -it

That way, the child isn’t memorizing 30 words.
They’re learning one sound pattern and swapping the first letter.

CVC mastery builds decoding confidence.

Without this foundation, everything else becomes memorization.

---

🟡 Level 2 – Blends (br, cr, st, tr)

Now we gently increase difficulty.

Instead of one consonant at the beginning, we introduce two that blend together:

• br → brush

• cr → crab

• st → star

• tr → tree

Notice something important:

In blends, both sounds are heard.

b + r → br
s + t → st

The child must now process:

Two consonant sounds → vowel → ending sound.

Cognitively, this is a big step up from CVC.

This is where phonemic awareness deepens.

But because they’ve already mastered blending in Level 1, this feels like a challenge — not a shock.

---

🔵 Level 3 – Digraphs (sh, ch, th)

Now we introduce something different.

Digraphs are pairs of letters that make one sound.

• sh → ship

• ch → chip

• th → thin

Here’s the twist:

In blends, both letters keep their sound.
In digraphs, the two letters become a new sound.

This requires a mental shift.

The child must now learn:

“Sometimes two letters behave like one.”

If your app visually groups these letters (for example, slightly closer spacing or same color), it helps reinforce this concept.

This level is powerful because it expands reading ability dramatically. Suddenly:

ship
shop
thin
chat

become decodable instead of mysterious.

---

🟣 Level 4 – Silent e (Magic e)

This is where things feel magical.

Because they are.

We teach the child:

When an “e” comes at the end, it changes the vowel sound.

cap → cape
tap → tape
hat → hate

This is the moment reading feels powerful.

The child sees:

“Wait… I can change the sound just by adding one letter?”

Silent e teaches:

• Long vowels

• Pattern transformation

• Predictive decoding

It’s not just a new rule — it’s a reading upgrade.

And because the child has already mastered short vowel sounds in Level 1, this makes sense rather than feeling random.

---

🔴 Level 5 – Sight Words

Now we introduce something different.

Sight words are words that don’t always follow decoding rules:

• the

• was

• said

• come

• you

These must be recognized instantly.

But here’s the important part:

Sight words should come after decoding skills are strong.

Why?

Because if you introduce too many irregular words too early, children start memorizing everything instead of decoding.

Decoding builds independence.

Sight words build fluency.

Both matter — but sequence matters more.

---

Why This Roadmap Works

This progression mirrors cognitive development.

It moves from:

Simple and predictable →
to complex but logical →
to rule-shifting patterns →
to exceptions.

Each level builds directly on the previous one.

It’s not random vocabulary expansion.
It’s structured neural layering.

---

If You’re Building a Phonics SPA

Here’s what this means practically:

Don’t unlock random words.

Unlock patterns.

Instead of:

“Today’s 20 new words”

Design:

“Today we master -at family”

And don’t move forward until blending feels automatic.

Your app becomes:

Less of a word game
More of a reading gym

---

The Bigger Picture

When a child masters:

CVC → Blends → Digraphs → Silent e → Sight words

They move from:

“I recognize some words”

to

“I can read.”

That shift is enormous.

It’s the difference between dependency and independence.

---

If you’re building long-term, this 5-level roadmap gives you:

• Curriculum clarity

• Feature sequencing

• UX progression

• Adaptive learning milestones

And most importantly:

It respects how the child’s brain actually develops.

<<< Previous Chapter   

If you have been following my blog lately, you must have come across the name “David Goggins” from the book “Can’t Hurt Me.” The tough guy wrote a follow-up to that book, giving more recent updates from his life in his 2022 book called “Never Finished.”

Like the first book, this one continues to offer tips, tricks, and techniques on how to become mentally strong.

First, let me be honest about this guy — his story moved me. I mean, I think I was regular at the gym for over a month — lost 4 kg.

But I was also exploring other books, and there was this one called “Light From Many Lamps” — which was teaching almost the antithesis of what Goggins was trying to preach.

And as I sit down to think about the two books, trying to settle myself, I realize that maybe neither book is wrong — just right in different contexts. Like Newton’s Laws of Motion and Einstein’s Theory of Relativity.

“Light From Many Lamps” by Lillian Watson teaches about happiness and enjoyment, faith in God, courage and fear, among other things.

I feel you need Goggins’ book in the morning — when you need motivation to get out of your warm, comfortable bed — and Lillian’s at night — when you want the storm of thoughts about events and people to settle down, when you want to soothe your soul to sleep.

I feel you need Goggins’ book when you are leading people in a professional or academic space — and Lillian’s book when you are leading or guiding people in your relationships.

I feel you need Goggins’ book when you want to go to war with yourself — and Lillian’s book when you want to make peace with yourself.

Personally, I feel Goggins’ book has helped me a lot — no pain, no gain — but yes, at the same time, I need Lillian’s teachings — about happiness, about contentment, about faith, about the good in the world — when I am in bed at night, trying to fall asleep.
