Why start with S A T P I N? Why not A-Z?

Learning to read is not as easy as ABC. Learning to read might look simple on the surface, but it’s much more complex than memorizing the alphabet. If we want children to become confident readers and writers, how we introduce instruction really matters. This post explores why a systematic, carefully planned sequence is the most effective way to support early reading and spelling.

Why Not A–Z?

Starting at A and finishing at Z feels logical, but the English alphabet code doesn’t work in such a neat, straightforward way. English is complex, and children benefit most when new sounds and letters are introduced in small, manageable steps, moving from simple to more complex patterns. That’s why many high-quality phonics programs begin with the letters S A T P I N rather than the alphabet in order.

Starting at A and finishing at Z might seem like a good idea, but it doesn’t quite work that way for effective practice. The English alphabet code is not the easiest to learn. A systematic sequence that works in tiny, incremental steps from simple to complex is best. Many programs use the letters S A T P I N to introduce the alphabet code. Why not A-Z?

Why use S A T P I N?

The use of these six letters is all about frequency. This combination of letters generates lots of words for sound manipulation activities. The letters S A T P I N also include two continuous sounds /ssssss/ and /nnnnnn/. Continuous sounds are a good starting point for blending because they can be stretched and held for a long time.

It’s all about the sounds — not letter names.

When children build words using sounds, they begin to understand how reading and spelling connect. Linking phonemes (sounds) to graphemes (letters) shows children that reading, spelling, and writing are not separate skills—they support each other.

Word building is a powerful activity

Helps children hear and manipulate sounds
Shows how changing one sound creates a new word
Provides a meaningful context for learning phonics

Instead of memorising isolated facts, children actively use what they’re learning.

Children need lots of playful practice — it is essential! Word building, games, playful activities, short decodable sentences, and texts that use previously taught knowledge are ideal for repeated practice.

Students should get as much repetition and consolidation as they need so no gaps appear along the way.

Why a Cumulative Approach Matters

A cumulative practice continually revisits and reinforces what children have already learned, preventing gaps from forming later on. This kind of structure supports all learners and builds a strong foundation for reading and spelling success. And if there’s one thing we know for sure every child loves to play. Learning might be challenging at times, but when there’s a playful element, the load feels lighter—and progress keeps moving forward.
