Year 7 Math Practice Questions and Topics
Year 7 (ages 11–12) is the first year of secondary school, and mathematically it's where algebra stops being an occasional topic and becomes a constant thread running through everything else. Children formalise work with negative numbers (including calculating with them, not just recognising them), study factors and primes properly, consolidate fractions/decimals/percentages from primary school into more demanding forms, and begin genuine algebra: writing and simplifying expressions, and solving simple equations. Geometry work on angles and area/volume continues at a higher level, ratio is applied more broadly, and probability is introduced as a topic in its own right for the first time.
By the end of Year 7, a student should confidently add, subtract, multiply and divide negative numbers, find factors and prime factors of a number, simplify a simple algebraic expression by collecting like terms, solve a one-step or two-step equation, and calculate a basic probability as a fraction.
The most common difficulty is negative numbers, specifically multiplication and division of them — the "two negatives make a positive" rule is easy to state and consistently misapplied under pressure, especially in multi-step calculations where a student loses track of how many negative signs they've already accounted for. The second frequent struggle is the jump from arithmetic to algebra itself: many students can substitute a number into an expression like "2n + 3" without issue, but struggle to manipulate the expression itself (simplifying, rearranging) because it no longer has one fixed numerical answer to check against, which feels unfamiliar and unanchored after years of arithmetic.
This year sets the tone for the whole of secondary maths — Years 8 and 9 build directly on this algebraic foundation, expanding it into factorising, more complex equations and eventually the full GCSE syllabus, so gaps here tend to widen rather than close on their own.
Parents can help most by normalising algebra as just another kind of arithmetic rather than something mysterious — practising negative number calculations regularly (temperature differences are a genuinely useful real-world context) and encouraging a student to explain what a letter in an equation actually represents, rather than treating it as a symbol to move around by rule alone.

Y7m Negative Numbers
Work out -4 + 9.
- 5✓ Correct
- -13
- 4
- 6
Why: -4 + 9 = 5.
Work out -5 + (-8).
- -12
- -13✓ Correct
- -14
- 3
Why: -5 + (-8) = -13.
Work out -6 × 7.
- -44
- -42✓ Correct
- 42
- -41
Why: A negative and a positive make a negative: -42.
Work out -5 − (-9).
- 5
- -14
- 4✓ Correct
- 2
Why: Subtracting -9 gives -5 + 9 = 4.
Y7m Factors Primes
Which number is prime?
- 21
- 13✓ Correct
- 15
- 9
Why: 13 has only two factors: 1 and 13.
What is the lowest common multiple of 4 and 6?
- 24
- 10
- 12✓ Correct
- 2
Why: The smallest number both divide into is 12.
What is the HCF of 24 and 36?
- 6
- 4
- 12✓ Correct
- 72
Why: The largest number dividing both is 12.
What is the LCM of 8 and 12?
- 4
- 24✓ Correct
- 96
- 48
Why: Multiples of 8: 8, 16, 24. 12 also divides 24.
Y7m Fdp
Write 0.4 as a fraction in its simplest form.
- 4/10 only
- 2/5✓ Correct
- 1/4
- 2/4
Why: 0.4 = 4/10 = 2/5.
Write 3/8 as a decimal.
- 3.8
- 0.375✓ Correct
- 0.38
- 0.83
Why: 3 ÷ 8 = 0.375.
Increase 250 by 12%.
- 262
- 280✓ Correct
- 238
- 300
Why: 12% of 250 is 30, so 250 + 30 = 280.
A price falls from £80 to £68. What is the percentage decrease?
- 20%
- 18%
- 12%
- 15%✓ Correct
Why: Decrease is £12, and 12 ÷ 80 × 100 = 15%.
Y7m Expressions
Simplify 8a − 3a + 2a.
- 9a
- 7a✓ Correct
- 13a
- 3a
Why: 8 − 3 + 2 = 7, giving 7a.
Expand 5(2x − 3).
- 10x + 15
- 10x − 15✓ Correct
- 10x − 3
- 7x − 15
Why: 5 × 2x = 10x and 5 × (−3) = −15.
Y7m Equations
Solve 4x = 36.
- 9✓ Correct
- 8
- 36
- 10
Why: Divide by 4: x = 9.

- 18
- 5
- 6✓ Correct
- 7
Why: 3x = 18, so x = 6.
Y7m Sequences
A sequence has nth term 3n + 2. What is the 10th term?
- 30
- 35
- 23
- 32✓ Correct
Why: 3 × 10 + 2 = 32.
Y7m Angles
Find the sum of interior angles of a hexagon.
- 360
- 540
- 900
- 720✓ Correct
Why: (6 − 2) × 180 = 720°.
