Year 9 is the awkward bridge year: still Key Stage 3 in school life, but already starting GCSE habits. This page gives free Year 9 Maths practice from GradeNinja's own bank - 58 auto-marked questions across 2 Year 9 topic sets.
The aim is not to cram GCSE papers early. It is to make the first GCSE topics feel normal: short retrieval practice, clear corrections, and enough repetition that classwork sticks before Year 10 gets busy.
Use these as ten-minute checks after a lesson or before homework. If you miss one, read the explanation, then come back tomorrow and answer it cold.
Year 9 questions are pulled from late Key Stage 3 and foundation GCSE bridge material. They should feel harder than Year 8, but they are not meant to be full Year 11 exam questions.
Answer first, then reveal. The useful bit is the retrieval attempt, not reading the answer. If a topic keeps going wrong, paste the homework or Google Classroom text into GradeNinja's Classroom import tool and turn it into a focused pack.

90°
The angle in a semicircle is always 90°. Any angle subtended by a diameter at the circumference is a right angle.
2³ × 3² × 5
360 = 2 × 180 = 2 × 2 × 90 = 2 × 2 × 2 × 45 = 2 × 2 × 2 × 9 × 5 = 2³ × 3² × 5.
opposite ÷ hypotenuse
Remember SOH-CAH-TOA. SOH: Sin = Opposite / Hypotenuse. CAH: Cos = Adjacent / Hypotenuse. TOA: Tan = Opposite / Adjacent. The hypotenuse is always the longest side, opposite the right angle.
4
In y = mx + c, the gradient is m. Here m = 4, so the gradient is 4.
4.5 × 10⁴
Standard form needs a number between 1 and 10 multiplied by a power of 10. 45,000 = 4.5 × 10⁴.
4.7 × 10^-4
Standard form needs a number from 1 up to 10 multiplied by a power of 10. Moving 0.00047 four places gives 4.7 × 10^-4.
2:3
The HCF of 24 and 36 is 12. Dividing both by 12 gives 2:3.
(x + 2)(x + 3)
We need two numbers that multiply to 6 and add to 5: those are 2 and 3. So x² + 5x + 6 = (x + 2)(x + 3).
x² + x − 6
Use FOIL: First (x × x = x²), Outer (x × −2 = −2x), Inner (3 × x = 3x), Last (3 × −2 = −6). Collect like terms: x² + (−2x + 3x) − 6 = x² + x − 6. FOIL always works for expanding double brackets.
Union (all elements in either set)
In set notation, the symbol ∪ represents the union of two sets, which includes all elements that are in either set. This means if an element is in set A or set B, it is included in A ∪ B. Key concept: union combines elements from both sets.
£150
Total parts = 3 + 5 = 8. One part = 240 ÷ 8 = £30. Larger share = 5 × 30 = £150.
3
From equation 1: x = 5 − y. Substitute into equation 2: 2(5 − y) + 3y = 12 → 10 − 2y + 3y = 12 → y = 2. Then x = 5 − 2 = 3. Check: 3 + 2 = 5 ✓ and 2(3) + 3(2) = 6 + 6 = 12 ✓.
10 cm
Pythagoras: c² = 6² + 8² = 36 + 64 = 100. c = √100 = 10 cm.
The median and interquartile range
Cumulative frequency graphs let you read off the median (at the 50th percentile), lower quartile Q1 (25th percentile), and upper quartile Q3 (75th percentile). The interquartile range (IQR) = Q3 − Q1 and measures the spread of the middle 50% of data.
14
Substituting x = 4 into the function f(x) = 3x + 2 gives f(4) = 3(4) + 2 = 14. This demonstrates how to evaluate a linear function.
0 to 1
Probability ranges from 0 (impossible) to 1 (certain).

Start revising free →They are bridge questions: harder than early Key Stage 3, but not pitched as full Year 11 GCSE exam papers. The point is to prepare the habits and core knowledge early.
Yes. Use Classroom import in the app: paste the Google Classroom post, homework email or assignment brief and it turns the topics into practice questions and flashcards.
Short and often. Ten minutes after a lesson or a few times a week is more useful than one long session before a test.
