Our Pedagogy

The Framework Behind Every Sigma Lesson

As a parent, you shouldn't have to take it on faith that your child is making progress. You deserve to understand exactly how they're being taught — and why it works. The Sigma 6E Method™ is a structured, research-informed teaching sequence applied in every lesson, by every tutor, every single week.

The Core Problem

Why Most Tutoring Doesn't Work — And What We Do Differently

Without a consistent framework, tutoring is just reactive gap-filling. A different topic every session. A different approach every time. Your child might improve slightly, but they never build the deep mathematical thinking that IGCSE exams actually test.

The 6E Method™ gives every lesson a deliberate structure — from how we open the session to how we close it — so your child isn't just learning maths, they're learning how to think mathematically. That's the skill that determines grades.

Six Stages. One Framework. Every Lesson.

How We Teach

Stage 01 / 06

Evoke

Preparing the Brain to Learn

Before introducing anything new, we prepare your child's brain to receive it. Using targeted retrieval practice, we bring previous learning to the surface — strengthening the memory pathways that connect old knowledge to new. This is a deliberate technique grounded in cognitive science, designed to reduce the "forgetting curve" that causes students to lose knowledge between sessions.

What this means for your child: They retain more, week on week, and enter each lesson ready to build — not re-learn.

Stage 02 / 06

Explain

Clarity Without Overload

New mathematical concepts are introduced through careful, step-by-step modelling. We start with the simplest version of the idea, ensure it's understood, then progressively increase complexity. We never move on until the foundation is solid. Our educators don't just present maths — they architect understanding deliberately, so no student is ever left sitting in confusion.

What this means for your child: They don't sit in lessons feeling lost. They follow every step — and they know when they've understood something, because they can actually do it.

Stage 03 / 06

Engage

Why Small Groups Change Everything

This is where Sigma's small-group model becomes a genuine academic advantage. Rather than listening passively, your child actively discusses solutions, identifies errors, and reasons through problems alongside carefully matched peers. Mathematical discussion deepens understanding in a way that solo study simply cannot replicate.

What this means for your child: They don't just hear maths explained — they articulate it themselves. Articulating a concept is the truest test of whether you've understood it.

Stage 04 / 06

Execute

Building Real Exam Fluency

Understanding a method once is not the same as being able to use it under pressure. Students apply what they've learned independently — starting from guided examples and progressing to unassisted problem-solving. The difficulty increases deliberately and gradually, so confidence and competence grow together.

What this means for your child: By the time they face the real exam, they've already solved problems like it dozens of times. There are no surprises.
E

Stage 05 / 06

Examine

Closing the Gap Between Class and Exam Room

There is a significant difference between understanding maths in a lesson and performing under timed, exam conditions. This stage bridges that gap. Students tackle genuine IGCSE past-paper questions, practise structuring written answers, and develop the exam technique that mark schemes reward.

What this means for your child: They don't just know the maths — they know how to communicate it in a way that earns marks. That distinction is often the difference between a B and an A.
E

Stage 06 / 06

Empower

Reflection, Metacognition, and Ownership of Learning

We close each lesson with structured metacognitive reflection, helping students evaluate what they now understand, identify remaining misconceptions, and develop the self-regulation skills needed for long-term academic success. This is not a motivational exercise — it is a cognitively rigorous process that trains students to think about their own thinking, close their own gaps, and take genuine ownership of their improvement.

What this means for your child: They leave each lesson knowing precisely what they have mastered and what still needs work — developing the academic self-awareness that drives sustained progress, not just short-term grade improvement.
