What the September 2026 Ofsted Update Means for Early Years Practice
The updated Ofsted Early Years Inspection Toolkit, which comes into force in September 2026, places a renewed emphasis on the explicit teaching of mathematics. Additional evidence gathering prompts have been introduced to support inspectors in evaluating how settings teach mathematics intentionally and effectively.
This is not about formal teaching. Rather, it highlights the importance of purposeful teaching, skilled interactions and a carefully planned curriculum that supports children to develop deep mathematical understanding from an early age.
Mathematics has always been a fundamental part of the Early Years Foundation Stage (EYFS). However, the revised inspection toolkit serves as a timely reminder that mathematical learning should be woven into everyday experiences, supported by knowledgeable practitioners who recognise and extend opportunities for children to think mathematically.
Mathematics: More Than Counting
The EYFS framework states that developing a strong grounding in number is essential if children are to acquire the building blocks needed to excel mathematically.
Children should:
- Count confidently
- Develop a deep understanding of numbers to 10
- Understand relationships between numbers
- Recognise patterns within numbers
- Develop spatial reasoning skills
- Explore shape, space and measures
- Build positive attitudes towards mathematics
Effective mathematics teaching is therefore much broader than teaching children to recite number sequences. It includes helping children understand what numbers mean, how they relate to one another and how mathematical thinking helps them make sense of the world around them.
The Role of the Practitioner
The Ofsted update reinforces the importance of practitioners’ interactions in supporting mathematical development.
Children do not learn mathematics simply by having resources available. They learn through meaningful experiences, careful modelling, questioning and discussion with practitioners who understand mathematical progression.
Practitioners should:
- Notice and respond to mathematical moments during play
- Introduce mathematical vocabulary naturally and consistently
- Encourage children to explain their thinking
- Support children to solve problems independently
- Create opportunities for repetition and practice
- Foster curiosity and confidence
Importantly, mathematics should be enjoyable. Children need to feel safe to experiment, make mistakes and try again.
Developing Strong Number Sense
Research consistently shows that secure number sense is one of the strongest predictors of later mathematical success.
Children need frequent opportunities to:
- Count meaningful objects
- Compare quantities
- Recognise small groups without counting (subitising)
- Explore patterns within numbers
- Link numerals to quantities
- Solve simple real-life problems
Manipulatives play a crucial role in this process. Resources such as:
- Pebbles
- Counters
- Loose parts
- Number tracks
- Tens frames
- Counting blocks
help children visualise mathematical concepts and develop deeper understanding.
For example, when children use a tens frame to organise objects, they begin to see patterns and relationships within numbers rather than relying solely on rote counting.
Mathematics in Everyday Contexts
One of the most effective ways to develop mathematical understanding is through real-life experiences.
Children learn best when mathematics has purpose and meaning.
Throughout the day practitioners can draw attention to numbers and mathematical concepts by discussing:
- Snack time (“We need four cups. How many do we have already?”)
- Registration (“How many children are here today?”)
- Outdoor play (“Which wellies are bigger?”)
- Tidying up (“Can you put three cars in the garage?”)
- Going home routines (“How many sleeps until Friday?”)
Numbers are everywhere: in street signs, bus stops, house numbers, calendars and clocks. The more children see mathematics used in meaningful contexts, the more likely they are to understand and apply it independently.
Supporting Babies and Toddlers
Mathematical learning begins long before children can count accurately.
For children from birth to three years, practitioners can support mathematical development by:
- Singing number rhymes and finger games
- Counting fingers, toes and everyday objects
- Drawing attention to changes in quantity
- Using language such as “more”, “lots”, “all gone” and “another”
- Providing opportunities to fill, empty, stack and sort
- Encouraging counting-like behaviours
At this stage, the focus is on exploration and exposure rather than accuracy. Young children build understanding through repeated experiences and interactions.
Building Mathematical Thinking Through Patterns
Patterns are at the heart of mathematics.
Research suggests that children’s ability to recognise and create patterns forms an important foundation for later mathematical thinking and reasoning.
Children naturally notice patterns in:
- Songs and rhymes
- Daily routines
- Nature
- Fabrics and artwork
- Movement and music
Practitioners can support pattern awareness by:
- Discussing patterns during play
- Using language such as “same”, “repeat” and “next”
- Encouraging children to create their own patterns
- Exploring simple repeating patterns such as ABAB
- Helping children identify mistakes in patterns
Importantly, children should have opportunities to invent their own patterns rather than simply copying adult-made examples. This supports reasoning, prediction and problem-solving skills.
Developing Spatial Reasoning
The revised EYFS guidance continues to emphasise the importance of spatial reasoning across all areas of mathematics.
Spatial reasoning involves understanding:
- Shape
- Position
- Movement
- Direction
- Size
- Distance
These skills underpin later learning in geometry, problem-solving and mathematical reasoning.
Children develop spatial reasoning through activities such as:
- Building with blocks
- Constructing dens
- Completing puzzles
- Climbing and navigating spaces
- Using shape sorters
- Exploring containers and capacity
Practitioners should introduce rich mathematical language throughout these experiences, including words such as:
- Inside
- Outside
- Above
- Below
- Behind
- In front
- Corner
- Curved
- Straight
- Heavy
- Light
The more opportunities children have to hear and use this vocabulary, the stronger their conceptual understanding becomes.
Creating a Positive Mathematical Culture
Perhaps one of the most important messages within both the EYFS framework and the updated inspection toolkit is that children should develop positive attitudes towards mathematics.
Children should learn that mathematics is something they can explore and enjoy.
Practitioners can foster this by:
- Celebrating effort rather than simply correct answers
- Encouraging children to explain their ideas
- Modelling curiosity
- Valuing different approaches to solving problems
- Treating mistakes as learning opportunities
- Creating an environment where children feel confident to “have a go”
When children feel successful and capable, they become more willing to tackle challenges and persist with problem-solving.
What Inspectors May Be Looking For
With mathematics teaching now explicitly referenced in the updated inspection toolkit, settings should be able to demonstrate:
- A clear mathematical curriculum with logical progression
- Strong practitioner knowledge of mathematical development
- Intentional teaching alongside child-led exploration
- Effective use of mathematical vocabulary
- Opportunities for children to develop number sense
- Rich experiences in pattern, shape, space and measure
- Meaningful use of mathematics across the daily routine
- Positive attitudes towards mathematical learning
Inspectors are likely to be interested not simply in what resources are available, but in how practitioners use them to deepen children’s understanding.
Final Thoughts
The September 2026 Ofsted inspection toolkit update is not introducing a new requirement. It reinforces what high-quality early years practice has always recognised: mathematics is a vital part of children’s understanding of the world.
Effective mathematical teaching happens when practitioners intentionally create opportunities for children to explore, notice patterns, solve problems, develop number sense and talk about their thinking.
By embedding mathematics throughout everyday experiences and providing rich opportunities for exploration, practitioners help children develop the confidence, understanding and enthusiasm that form the foundation for future mathematical success.
Mathematics should not be seen as a separate subject in early years; it should woven through everything children do. The challenge for practitioners is to recognise those moments and transform them into meaningful learning opportunities.
