What Mathematics Looks Like at Hartlip School

At Hartlip School, mathematics is a core subject that helps children make sense of the world around them. Mathematics provides pupils with tools to analyse information, solve problems and communicate ideas clearly. Alongside its practical value, we believe mathematics should also be a source of delight, curiosity and intellectual excitement, fostering resilience, creativity and confidence.

Our mathematics curriculum is ambitious, inclusive and carefully sequenced in line with the National Curriculum for Mathematics, ensuring that all pupils develop secure knowledge, fluency and reasoning skills.

Our Vision for Mathematics

We want all pupils to see themselves as mathematicians. At Hartlip School, mathematics is taught in a way that promotes:

  • deep conceptual understanding

  • fluency and accuracy

  • mathematical reasoning and explanation

  • confidence in tackling problems and real‑life situations

Mathematics is not taught solely because it is useful, but because it develops logical thinking, perseverance and an appreciation of patterns and structure.

The Mathematics Curriculum

The National Curriculum areas taught at Hartlip School include:

  • Number

  • Measurement

  • Geometry (shape, position and direction)

  • Statistics

These areas are carefully sequenced across year groups to ensure clear progression, with regular opportunities to revisit, apply and deepen learning.

Our Teaching Approach: Mastery

We use White Rose Maths, NCETM Mastery of Number and Steps to Progress National Curriculum materials to deliver the mathematics curriculum effectively and consistently across the school. Steps to Progress supports clear progression, assessment and next steps, ensuring teaching is precisely matched to National Curriculum expectations.

A mastery approach ensures that:

  • key concepts are broken down into small, manageable steps

  • pupils develop a deep understanding before moving on

  • lessons focus on depth rather than acceleration

  • representations and structures support understanding

All pupils are encouraged to achieve success together, with challenge provided through depth of reasoning and problem‑solving rather than moving ahead prematurely.

Mathematics in EYFS and Key Stage 1

For our youngest children, mathematical learning is rooted in practical exploration and real‑life experiences. In addition to structured teaching based on White Rose Maths, children explore mathematical concepts through:

  • play‑based activities

  • manipulatives and concrete resources

  • stories, songs and everyday routines

  • cross‑curricular links

This approach ensures that children develop strong foundations in number sense, counting, comparison and pattern while maintaining curiosity and enjoyment.

In Key Stage 1, the Mastery of Number programme supports the development of automaticity, confidence and flexibility with number, preparing pupils for more complex mathematics as they progress.

Calculation and Fluency

Children are taught the three key methods of calculation:

  • mental calculation strategies

  • written methods using pencil and paper

  • use of a calculator, where appropriate, to support problem‑solving and real‑life applications

Fluency is developed through regular practice, varied representations and opportunities to apply skills in different contexts.

Reasoning and Problem‑Solving

Reasoning and problem‑solving are integral to every mathematics lesson. Pupils are encouraged to:

  • explain their thinking using mathematical language

  • justify answers and strategies

  • identify patterns and make connections

  • apply mathematics to unfamiliar and real‑life situations

This aligns with Ofsted expectations that pupils know more, remember more and do more over time.

Inclusion and Accessibility in Mathematics

Mathematics at Hartlip School is ambitious for all learners. Teaching is adapted to ensure accessibility without lowering expectations.

Inclusive practice includes:

  • use of concrete and pictorial representations

  • visual models and stem sentences

  • pre‑teaching of key vocabulary

  • flexible grouping and targeted adult support

  • adapted resources and tools where needed

All pupils are supported to engage with the full mathematics curriculum and to develop confidence and independence.

Assessment and Intervention

Assessment in mathematics is ongoing and used to inform teaching. Where pupils need additional support, targeted interventions are carefully planned and delivered, ensuring pupils quickly catch up and re‑engage confidently with whole‑class learning.

Interventions are:

  • closely linked to classroom teaching

  • time‑limited and purposeful

  • reviewed regularly for impact

A Strong Foundation for the Future

Through high‑quality teaching, a mastery approach and inclusive practice, Hartlip School ensures that pupils develop secure mathematical understanding and confidence. Children leave Hartlip School as fluent, confident problem‑solvers, well prepared for the next stage of their education and able to use mathematics creatively and effectively in the wider world.
