11+ maths practice:
fifteen questions,
every answer worked

Fifteen original 11+ maths practice questions in three timed sets, written in the style of the main tests and not copied from any real paper. Most 11+ maths is built on the KS2 curriculum up to Year 5; what makes it harder than school work is speed and multi-step problems, not new topics.

What is in 11+ maths, and how should you use this page?

11+ maths tests the key stage 2 curriculum, mostly up to the end of Year 5, under time pressure and with more steps per question than a school worksheet. The fifteen questions below are grouped into three short timed sets: number and calculation, problem solving and algebra, and measurement, geometry and data.

Have your child do a set without a calculator and within the suggested time, then mark it against the worked answers. Look at the method as well as the result: a right answer reached slowly is still a problem in a timed test.

This page covers 11+ maths only. ClassArc teaches the maths part of 11+ preparation; we don't teach verbal reasoning, non-verbal reasoning or English, so for those you will need other preparation.

11+ maths practice set A: number and calculation

Five questions, no calculator. Answers are under each question; cover them first.

1. Fractions and percentages of amounts

Multiple choice

What is ⅜ of 96 added to 25% of 64?  A) 44  B) 48  C) 52  D) 56  E) 60

C) 52. 96 ÷ 8 = 12, × 3 = 36. 25% of 64 is 64 ÷ 4 = 16. 36 + 16 = 52.

Where it usually goes wrong Dividing by the numerator. The denominator says what to divide by.

2. Rounding large numbers

Written answer

Round 4,596,381 to the nearest ten thousand.

4,600,000. The ten-thousands digit is 9 and the next digit is 6, so round up: 59 ten-thousands becomes 60.

Where it usually goes wrong Writing 4,590,000 or 4,500,000 when the 9 rolls over.

3. Missing numbers

Written answer

7 × ☐ − 18 = 45

9. Work backwards: 45 + 18 = 63, and 63 ÷ 7 = 9.

4. Remainders and common multiples

Written answer

What is the smallest number greater than 1 that leaves a remainder of 1 when divided by 2, 3, 4, 5 or 6?

61. It is one more than a common multiple of all five. The lowest common multiple is 60 (it needs 2 × 2, 3 and 5), so 60 + 1 = 61. Check: 61 ÷ 4 = 15 r 1.

5. Comparing fractions and decimals

Multiple choice

Which is largest?  A) ⅝  B) 0.6  C) 13/20  D) 7/12

C) 13/20. As decimals: 0.625, 0.6, 0.65 and about 0.583. Twentieths convert quickly to hundredths: 13/20 = 65/100.

11+ maths practice set B: problem solving and algebra

Five multi-step problems. Trying values is a perfectly good method at this age.

6. Pens and rulers

Written answer

A pen costs p pence. A ruler costs 15p more than a pen. Three pens and two rulers cost £1.80 altogether. How much does one pen cost?

30p. Without the extra 15p on each ruler, five items would cost 180 − 30 = 150p, so 30p each. Algebra: 3p + 2(p + 15) = 180, 5p = 150. Check: 90 + 90 = 180.

7. Ages

Written answer

Sam is three times as old as his sister. In 4 years he will be twice as old as her. How old is Sam now?

12. Try the sister at 4: Sam is 12. In four years, 8 and 16, and 16 is double 8.

8. Sequences

Written answer

What comes next? 3, 7, 15, 31, …

63. Each term doubles and adds 1: 31 × 2 + 1. Or: the gaps 4, 8, 16 double, so the next gap is 32.

9. Sharing in a ratio

Written answer

Mia and Tom share 84 sweets in the ratio 3 : 4. How many more sweets does Tom get than Mia?

12 more. Seven parts, so each is 84 ÷ 7 = 12. Mia 36, Tom 48. The difference is exactly one part.

Where it usually goes wrong Answering 48, the share, when the question asks how many more.

10. Up, then down

Written answer

A coat costs £60. Its price rises by 20%, then the new price is cut by 20% in a sale. What is the sale price?

£57.60. £60 + £12 = £72; 20% of £72 is £14.40; £72 − £14.40 = £57.60.

Where it usually goes wrong Answering £60. The decrease is 20% of a bigger number, so it removes more than the rise added.

11+ maths practice set C: measurement, geometry and data

Five questions where units, cases and checking matter as much as the arithmetic.

11. Time

Written answer

A train leaves at 14:47 and the trip takes 1 hour 38 minutes. When does it arrive?

16:25. 14:47 + 1 hour = 15:47. Thirteen minutes reaches 16:00, leaving 25 more.

Where it usually goes wrong Adding times like decimals and writing 16:85.

12. Perimeter to area

Written answer

A rectangle has a perimeter of 34 cm and one side of 12 cm. What is its area?

60 cm². The two 12 cm sides make 24, leaving 10 cm for the other two, so 5 cm each. 12 × 5 = 60.

13. Isosceles triangles

Written answer

One angle of an isosceles triangle is 40°. What could the other two be? Give both answers.

40° and 100°, or 70° and 70°. If 40° is one of the equal pair, the third is 100°. If it is the odd one, the other two share 140°.

Where it usually goes wrong Stopping at one case. 11+ papers reward checking for a second.

14. The mean

Written answer

The mean of five numbers is 12. Four of them are 8, 15, 10 and 14. What is the fifth?

13. The total is 12 × 5 = 60. The four known numbers make 47, and 60 − 47 = 13.

15. Cubes in a box

Written answer

How many cubes with 2 cm edges fit exactly inside a box measuring 10 cm × 6 cm × 4 cm?

30. Along each edge: 5, 3 and 2 cubes, and 5 × 3 × 2 = 30.

Where it usually goes wrong Dividing the volumes. It works here only because every edge divides exactly by 2; counting along the edges always works.

Scoring: 13–15 correct within the times is a strong result on this set. 9–12 points to speed or particular topics. Below 9, start with the set that had the most errors.

How the main 11+ tests present maths

Which test your child sits depends on the school or area, not the family, and arrangements change more often than parents expect. Always check the school's or local authority's own admissions information.

TestCommonly used byHow the maths is set
GL AssessmentMany grammar-school areas in EnglandOn paper. Depending on the area, multiple choice with a separate answer sheet or written answers. Content mainly from KS2.
ISEB Common Pre-TestsMany independent schools, usually in Year 6 or late Year 5Online and adaptive: each question is chosen from how the last was answered. Maths draws on the national curriculum up to the end of Year 5, with a standard time of 40 minutes.
School-set or consortium papersMany independent schools and some grammar schoolsUsually written answers with working and longer multi-step problems. Schools often publish their own guidance or sample papers.

ISEB details from ISEB's published Common Pre-Tests framework. Other providers are used in some areas; the area's admissions pages will name the test, its format and the registration deadline, which for grammar schools usually falls in the spring or summer of Year 5.

Tips for 11+ maths that save marks on the day

ClassArc teaches the maths part of 11+ preparation, one-to-one

ClassArc's 11+ classes are maths only: 55 minutes, one teacher and one child, the same teacher every week. The first class checks the KS2 foundations — starting a little above where your child is and working back until the ground holds — then later classes move to timed problem solving in the style of your child's actual test.

Because teacher and child write on the same page, the teacher sees how a multi-step question is approached, not just the final number. Classes for this age are from £11 each on the largest block. For verbal reasoning, non-verbal reasoning and English you will need separate preparation.

Maths

the only 11+ paper we prepare for — we say so up front

More for Years 5 and 6

What maths is in the 11+?
Mostly key stage 2 content up to the end of Year 5, with some tests reaching into early Year 6: arithmetic, fractions, decimals and percentages, number properties, multi-step word problems, simple algebra, measurement, geometry and data. The difference from school work is speed and the number of steps per question.
When is the 11+ taken?
Most grammar-school tests are sat in the September of Year 6, with registration in the spring or summer of Year 5. Independent schools vary, and the ISEB Common Pre-Tests are usually taken in Year 6 or late Year 5. Check dates with the school or local authority.
Does ClassArc prepare children for verbal and non-verbal reasoning?
No. ClassArc teaches the maths part of 11+ preparation only. We would rather say that plainly than suggest otherwise; families usually cover reasoning and English separately.
Are these 11+ questions from real papers?
No. All fifteen are original questions written in the style of the main tests. For official practice, look at the sample materials the test provider or the school publishes.
