How do we support a pupil with dyscalculia in maths?

Start by adapting high-quality maths teaching: use manipulatives and visual models, teach number vocabulary explicitly, cut working-memory load. Then layer SEN support through assess-plan-do-review, diagnosis or not. You do not have to wait for a formal assessment to act. A pupil has special educational needs if they have a learning difficulty that calls for special educational provision, and that judgement is needs-led, not diagnosis-led (Children and Families Act 2014, section 20).

Adapt the everyday teaching first

The SEND Code of Practice is explicit that high-quality teaching, adapted for the individual pupil, is the first response to any pupil who has or may have SEN, and that extra intervention cannot make up for teaching that does not work for them (SEND Code of Practice 2015, paragraph 6.37). For a pupil stuck on number, that means changing how the maths is taught before adding anything on top.

The moves that help most in dyscalculia:

• Use manipulatives and visual models (Dienes base-10 blocks, Cuisenaire rods, number lines and arrays) so the pupil can see the maths rather than count in ones. The Education Endowment Foundation (2022) is clear these work only when you link the object to the idea out loud and plan to fade them, not leave them as a permanent prop.
• Teach the number vocabulary explicitly at the start of each topic (sum, product, difference, factor) rather than assuming it.
• Cut the working-memory load: give a times-table square and a formula crib sheet, break multi-step problems into steps, and let the pupil jot working rather than hold it in their head.
• Allow more processing time, keep the maths multi-sensory and practical, and check understanding before moving on.

Then run the graduated approach

Where good teaching alone is not closing the gap, the school provides SEN support through the four-part cycle: assess, plan, do, review (SEND Code of Practice 2015, paragraphs 6.44 to 6.56). Assess what the pupil can and cannot do in number and why; plan the specific adaptations and any targeted intervention with the class teacher and SENCO; do them consistently; then review the impact and decide what changes. Each cycle should draw on more frequent review and more specialist input than the last. Record this on the pupil’s SEN support plan so the next teacher does not start from scratch.

Escalate if progress stalls

If the gap keeps widening despite two or three review cycles, talk to the SENCO about a specialist dyscalculia or maths assessment. Some schools buy in an accredited specialist teacher, and the House of Lords Library (2024) notes specialist dyscalculia teaching is essentially high-quality maths teaching tailored to the individual, usually delivered in class. Where needs are significant and the pupil is not making adequate progress, the school or a parent can request an education, health and care needs assessment from the council.
