Regular number-sound systems
Why spoken number structure, place value, regularity, and brevity matter when multiplication facts are encoded into sound.
The Book Behind ChantCode
ChantCode: Multiplication
A Multiplication Code Stored in Sound
The book is the primary long-form explanation of the ChantCode method. It examines how number sounds, compact multiplication chants, memory storage, and retrieval practice fit together.

Core Ideas
What the book explains
The Chinese multiplication-chant tradition
How the traditional 9×9 chant functions as compact spoken memory, while remaining an educational practice rather than a controlled proof of ChantCode.
The 36 core facts
Why the 1s can be understood by rule and commutative duplicates need not be stored twice, leaving the non-duplicate 2s–9s core for concentrated memorization.
From ordered chant to automatic recall
How children move from listening and sequence replay to random retrieval, mixed retrieval, and increasingly direct access to known facts.
The Central Question
Can regular number sounds help children perceive place value more clearly, reduce unnecessary processing during multiplication, and support the storage and retrieval of multiplication facts?
This is a design and research question, not a guaranteed result. The effectiveness of ChantCode should be evaluated through children's actual learning and testing data.
