🇬🇧 UKBODMAS/BIDMASGCSE 9-1A-Level MathsMastery Approach (since 2014)

UK Maths Education

BODMAS, GCSEs, A-Levels — and why England has been importing Shanghai's mastery method since 2014.

QUICK ANSWER

UK students use BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) — the British equivalent of PEMDAS. At 16, students take GCSE Maths (graded 9-1). Those continuing to A-Level study calculus, statistics, and mechanics. UK says "maths" (plural); the US says "math." Since 2014, England's National Curriculum has adopted a mastery approach influenced by Shanghai — fewer topics per year, taught more deeply.

BODMAS — UK Order of Operations

BODMAS: Brackets → Orders (powers/roots) → Division → Multiplication → Addition → Subtraction. BIDMAS replaces "Orders" with "Indices" — same rule. Division and Multiplication have equal priority (work left to right), as do Addition and Subtraction.

The UK Qualification Pathway

Stage Age Key maths content
Key Stage 1 (KS1) 5–7 Counting, basic addition/subtraction, simple shapes
Key Stage 2 (KS2) 7–11 Times tables, fractions, decimals, column arithmetic, basic algebra
Key Stage 3 (KS3) 11–14 Algebra, ratio, geometry, probability, statistics
GCSE (KS4) 14–16 Full curriculum; exam at 16; graded 9-1; Foundation and Higher tiers
A-Level (KS5) 16–18 Pure (calculus, algebra, trigonometry), Statistics, Mechanics
Further Maths A-Level 16–18 Complex numbers, matrices, further calculus — for strongest students

The Mastery Shift — England Imports Shanghai

Since 2014, England's Department for Education has invested £41 million in the "Maths Hubs" programme — importing the Shanghai mastery model. English teachers have visited Shanghai; Shanghai teachers have taught in England. Key changes brought from Shanghai:

  • Fewer topics per year, taught with greater depth
  • Whole-class teaching rather than differentiated group work
  • Concrete-Pictorial-Abstract progression
  • No ability streaming in primary school

Results have been encouraging: England's PISA 2022 score (489) is above the OECD average (472) for the first time, up from 493 in 2018 and 493 in 2015.

Why British English Says "Maths" Not "Math"

"Maths" is an abbreviation of "mathematics" — a plural noun in British English. The plural ending is kept: "physics," "economics," "maths." American English simplified it to the singular "math" in the 20th century. Australian, Indian, South African, and most Commonwealth varieties follow British "maths."

Frequently Asked Questions

What grade is GCSE 9 equivalent to in the US?
GCSE grade 9 (the highest) is equivalent to an A*/A in the old grading system. In US terms, it roughly corresponds to a very strong A (95%+ equivalent). GCSE grade 4 ("standard pass") ≈ US C. GCSE grade 7 ≈ A. The GCSE examination style — heavy on problem-solving, multi-step questions, and mathematical reasoning — is often considered more rigorous than US Algebra 2 at the same age.
How does UK GCSE maths differ from US Algebra?
GCSE Maths (taken at 16) covers number, algebra, ratio & proportion, geometry, probability, and statistics — a broader curriculum than US Algebra 1 or 2 alone. GCSE Higher tier includes proof, trigonometry, quadratics, and circle theorems. US students typically need Algebra 1, Geometry, and Algebra 2/Pre-Calculus across grades 9-11 to cover equivalent content.
Does UK use metric or imperial measurements?
Officially metric — UK science, medicine, and most commerce use metric units. However, imperial survives informally: miles and mph on roads, pints for beer and milk in pubs and dairies, stone and pounds for body weight in everyday speech, feet and inches for height. GCSE Maths includes both metric and imperial units and conversion between them.
What is the difference between BODMAS and BIDMAS?
They are the same rule with one letter changed. BODMAS uses "O" for Orders (powers and roots); BIDMAS uses "I" for Indices (another word for powers). Both stand for Brackets, Orders/Indices, Division, Multiplication, Addition, Subtraction. Division and Multiplication share equal priority (worked left to right), as do Addition and Subtraction. The US equivalent is PEMDAS and Canada uses BEDMAS.
What is the mastery approach in UK maths?
Since 2014 England's National Curriculum has adopted a "mastery" approach influenced by Shanghai and Singapore, backed by the £41 million Maths Hubs programme. It means covering fewer topics per year but in greater depth, whole-class teaching rather than ability streaming in primary school, and a Concrete-Pictorial-Abstract progression. England's PISA 2022 maths score (489) sits above the OECD average for the first time.
What A-Level maths options can UK students take?
After GCSEs, students aged 16-18 can take A-Level Maths, which combines Pure mathematics (calculus, algebra, trigonometry) with Statistics and Mechanics. The strongest students can additionally take Further Maths A-Level, covering complex numbers, matrices, and further calculus. A-Levels are the main academic qualification used for UK university admission.
