How Eastbury Community School transformed primary maths outcomes through mastery

Located in the heart of Barking and Dagenham, Eastbury Community School is a vibrant, diverse 3–19 all-through school serving a multicultural community in East London. Facing the universal challenge of ensuring equitable mathematical progress for pupils of all backgrounds and starting points, the primary department embarked on a transformational journey to move away from procedural, rote learning toward deep conceptual understanding and mathematical fluency.

By embedding a comprehensive mastery framework centered around child-led exploration, tactile manipulatives, mathematical dialogue, and structured journaling, Eastbury transformed its mathematics culture. Today, the primary department stands as a beacon of academic excellence: 93% of Key Stage 2 pupils achieve the Expected Standard in national mathematics assessments, and 46% reach Greater Depth — far exceeding national averages.

Here is how Eastbury Community School restructured its approach to mathematics, built an inclusive learning environment, and leveraged expert coaching to achieve exceptional results.

School context and the initial challenge

Serving a diverse East London community

Eastbury Community School operates as a two-form entry primary phase within a larger 3–19 all-through institution. With approximately 470 primary pupils on roll, the school’s intake reflects the rich cultural and demographic diversity of East London. Classrooms comprise learners with a wide variety of initial language profiles, educational backgrounds, and learning needs, including pupils who are Working Towards Expectations (WTE), English as an Additional Language (EAL) learners, and high-attaining pupils who require constant intellectual challenge.

The search for true conceptual mastery

Historically, traditional primary mathematics instruction across the UK relied heavily on teacher-led instruction at the front of the classroom: teachers demonstrated a single algorithm or procedure, and pupils attempted to replicate the steps in their workbooks. School leadership at Eastbury recognised that while procedural competence might allow some pupils to pass routine checks, it often failed to build long-term retention, mathematical confidence, or deep problem-solving abilities.

The school leadership team established a clear vision: every child can succeed in mathematics. To realise this vision, Eastbury needed a curriculum framework that moved beyond superficial procedural drills. They required a structured mastery approach built on:

• Deep Conceptual Understanding: Ensuring pupils understand why mathematical algorithms work, not just how to follow steps.
• Mathematical Language and Communication: Giving children the vocabulary and opportunity to discuss, debate, and reason mathematically.
• Concrete Manipulatives: Providing tactile learning tools (such as place value counters, base-10 blocks, and ten-frames) to ground abstract ideas in physical reality.
• Child-Led Independence: Shifting the teacher’s role from the central authority to a facilitator of inquiry and problem-solving.

To achieve these ambitious goals, Eastbury Community School partnered with Maths — No Problem! to adopt its Singapore-inspired mastery textbook scheme, professional learning resources, and accredited framework.

Inclusivity and closing the attainment gap

Empowering learners at all levels

In traditional teaching environments, differentiation often means giving low-attaining pupils simpler work and high-attaining pupils extended worksheets. This practice can lock lower-attaining children into low expectations while depriving them of rich mathematical discussion.

Eastbury’s mastery model — supported by the inclusive design of Maths — No Problem! — keeps the entire class working together on the same core mathematical concepts, achieving differentiation through depth and scaffolding rather than content acceleration.

“It’s really allowed children to be free in maths lessons, and I really enjoy it because I can see the different levels of children being able to enjoy maths,” says Mr Collyer, a Year 5 teacher at Eastbury. “It’s not necessarily just your Greater Depth children being able to go off — you can see the confidence of your Working-Towards children, your Lower-Ability children who might need that boost. They've got the confidence now to become more independent in their learning.”

By grounding abstract mathematics in physical manipulatives and visual representations, pupils with EAL or special educational needs (SEND) can grasp complex ideas without language acting as an insurmountable barrier. Simultaneously, high attainers deepen their understanding by justifying their strategies, evaluating alternative methods, and mentoring peers.

Exceptional outcomes and academic impact

KS2 SATs results: Outperforming national benchmarks

The systematic implementation of this high-quality mastery curriculum has delivered extraordinary, measurable results for Eastbury Community School.

"Our maths results are absolutely exceptional: 93% of our children achieve the expected standard for maths and 46% of our children achieve at greater depth, and that is due to Maths — No Problem!" says Aisha Raymond, Head of Primary at Eastbury.

In national Key Stage 2 assessments (SATs), Eastbury pupils achieve outcomes well above national averages:

Beyond test scores: Pupil voice and mindset shift

While statistical outcomes validate the academic rigour of the program, the qualitative impact on pupils' attitudes toward learning is equally striking. Pupil voice evaluations reveal that children at Eastbury no longer view mathematics as a daunting subject filled with rigid rules to memorise. Instead, they view it as a collaborative, creative, and engaging discipline.

Key qualitative shifts observed across the primary phase include:

• Elevated Mathematical Oracy: Pupils articulate their thought processes using precise mathematical vocabulary (e.g., regrouping, commutative, quotient, perimeter, bar model).
• Increased Resilience: A positive classroom culture has eliminated anxiety surrounding incorrect answers.
• Peer Collaboration: Children actively listen to alternative solution strategies and construct logical arguments to defend their mathematical thinking.

Leadership, quality assurance and professional development

Achieving consistency across an entire primary department requires more than just high-quality textbooks; it demands ongoing coaching, leadership alignment, and continuous professional development (CPD).

Strategic support from Maths — No Problem! consultants

Eastbury Community School’s journey to becoming an Accredited School was accelerated by deep, structured support from dedicated Maths — No Problem! professional consultants. Rather than applying a generic, one-size-fits-all training session, the consulting team worked closely with Eastbury’s senior leaders and subject leads to embed sustainable practices.

“We've had lots of support from Maths — No Problem!,” says Simon Hack, Associate Assistant Head at Eastbury. “We've had our consultant in, so we had our pupil voice, our quality assurance documents and our book looks documents all produced with the support of the maths consultant. It's been able to actually give individual feedback to all the different parts of a Maths — No Problem! lesson, which has helped massively, and which then has helped the consistency across the whole school.”

Key components of the Quality Assurance Framework

Through this partnership, Eastbury established robust internal monitoring mechanisms:

1. Targeted Book Looks: Reviewing pupil journals and workbooks to evaluate the progression from concrete exploration to abstract reasoning, checking for rich journal entries and reflection on mistakes.
2. Structured Pupil Voice Surveys: Interviewing learners across Year 1 through Year 6 to measure confidence, conceptual understanding, and enjoyment of mathematics.
3. Granular Lesson Feedback: Observing specific segments of the mastery lesson (Explore, Masterclass, Journaling, Guided Practice) to offer precise, actionable coaching to teachers.
4. Cross-Phase Moderation: Ensuring consistent expectations, vocabulary, and pictorial models are used seamlessly from Early Years and Key Stage 1 through Key Stage 2.

Key takeaways for school leaders

For primary heads, trust executives, and mathematics leads considering a transition to a mastery framework, Eastbury Community School’s journey offers several strategic insights:

• Commit to Child-Led Discovery: Limit initial teacher presentation time during lessons. Give pupils the autonomy to explore concepts using manipulatives and dialogue before formalising algorithms.
• Culture Precedes Computation: Create a classroom atmosphere where mistakes are celebrated as learning opportunities. When fear of failure is removed, mathematical risk-taking and depth of reasoning soar.
• Invest in Journaling for Metacognition: Provide unstructured, low-stakes spaces for children to explain their thinking, draw diagrams, and reflect on strategies.
• Prioritise School-Wide Consistency: Mastery is most powerful when children experience the same structure, vocabulary, and Concrete-Pictorial-Abstract (CPA) representations as they progress through year groups.
• Leverage Expert Coaching: Pair textbook resources with structured, professional consulting, book looks, and quality assurance frameworks to support teacher confidence and ongoing CPD.
