Ask a Manchester commuter how far apart the tram stops are and you will get a feeling, not a number. We measured it. Between the 99 named Metrolink stops in OpenStreetMap there are 101 pairs of neighbours, and the straight-line gaps between them average 952.9 metres. Yet half the gaps are shorter than 819.5 metres. Two honest answers, 133 metres apart, from the same list: that gap between the mean and the median is the whole of GCSE statistics in one tram map. This page explains how we teach maths to Manchester learners from the Year 4 multiplication tables check to Further Maths and adult refreshers, and uses the Metrolink as a running example.

In short
As an online maths tutor we teach Manchester learners live from age 6 to 67: primary number, times tables and the Year 6 SATs, KS3, GCSE maths at Foundation or Higher tier for AQA, Edexcel or OCR, IGCSE, A level Maths and Further Maths, and adult maths from GCSE maths resits to plain refreshers. Group classes hold between five and ten learners of matching level, and private lessons are on offer too. Lessons follow the national curriculum and the GCSE and A level specifications, and every learner works on real data as well as textbook questions. Our Manchester example is the Metrolink: across 101 pairs of neighbouring stops, the mean straight-line gap is 952.9 metres and the median is 819.5 metres, because a few long gaps on the lines out to Bury, Oldham and Rochdale pull the mean up. We charge nothing for the opening lesson; continuing costs USD 100 monthly for a group seat or USD 150 monthly for private teaching.

Manchester schools follow the national curriculum for England, so the stages below are the ones a Manchester child moves through. Adults join at whatever point they left off.
| Stage | Ages | What we concentrate on |
|---|---|---|
| Key Stage 1 | 5 to 7 | Counting, place value to 100, number bonds, simple fractions of shapes and quantities. |
| Key Stage 2 | 7 to 11 | Times tables to 12 × 12 before the Year 4 check, written methods, fractions and decimals, and the reasoning questions of the Year 6 tests. |
| Key Stage 3 | 11 to 14 | Algebra as a language, ratio, negative numbers, angle facts, and the first proper statistics. |
| GCSE | 14 to 16 | Foundation or higher tier: number, algebra, ratio, geometry, probability and statistics, including box plots and grouped data. |
| A level | 16 to 18 | Pure maths, statistics and mechanics; Further Maths for those who want more proof and more abstraction. |
| Adults | 18 to 67 | Refreshers, helping with homework, maths for work, and a return to GCSE content at an adult pace. |
The government says the multiplication tables check "is statutory for all year 4 pupils registered at state-funded maintained schools, special schools or academies, including free schools, in England". In lessons we treat the tables as facts to understand, not a chant: 7 × 8 is 56 because 7 × 8 is 7 × 4 doubled, and a child who sees that can rebuild a fact they forget.
By Year 6 the work is about reasoning. A child who can explain why 0.3 is bigger than 0.25 is ready for the tests; a child who only knows a rule about lining up digits is not yet.
From Year 7 we build algebra slowly and properly, because almost everything later depends on it. At GCSE we teach to the learner's exam board and tier, and at A level we keep the statistics tied to real data sets so that a hypothesis test is about something.
Our national pages go deeper on each stage: Key Stage 2, Key Stage 3, GCSE, A level and Further Maths.

The Manchester project
One list of 101 distances, measured by us, carries a learner from rounding at primary school to box plots at GCSE and spherical distance at A level.
On 1 October 2026 we downloaded the Metrolink routes from OpenStreetMap, the free map that volunteers keep up to date. The 23 route records name 99 stops. Wherever two stops sit next to each other on any route, we counted that pair once, which gives 101 pairs of neighbours. For each pair we took the straight-line distance between the mapped stop positions, the distance a bird would fly, not the length of track.
The shortest gap is 217.9 metres, from Market Street to Piccadilly Gardens in the city centre. The longest is 3,502.3 metres, from Bury to Radcliffe. Every number on this page is our own calculation from that download, and the map will change as volunteers edit it.
The mean gap is 952.9 metres. The median, the middle gap when all 101 are put in order, is 819.5 metres. So which is the typical distance between stops? A learner who says the mean is not wrong, and a learner who says the median is not wrong either. The interesting question is why they differ by 133 metres.
The answer is the shape of the data. Most gaps are short and similar, but a handful are very long, and all five of the longest are on the lines to Bury and to Oldham and Rochdale. Those few big values pull the mean upwards. The median only cares about the middle position, so it barely moves.
| Measure | Value | What it tells a learner |
|---|---|---|
| Mean | 952.9 m | Add all 101 gaps and share the total equally. |
| Median | 819.5 m | The 51st gap when they are sorted from shortest to longest. |
| Lower quartile | 621.2 m | A quarter of the gaps are shorter than this. |
| Upper quartile | 1,158.7 m | A quarter of the gaps are longer than this. |
| Interquartile range | 537.5 m | The spread of the middle half, which ignores the extremes. |
| Range | 3,284.4 m | Longest minus shortest, which is all about the extremes. |
| Gaps under 500 m | 16 | Mostly in the city centre and around Salford Quays. |
| Gaps over 1,500 m | 13 | Seven of them on the lines out to Bury, Oldham and Rochdale. |
The DfE content for GCSE maths asks for measures of "spread (range, including consideration of outliers, quartiles and inter-quartile range)". A common convention calls a value an outlier if it lies more than 1.5 interquartile ranges above the upper quartile. Here that fence is 1,158.7 + 1.5 × 537.5 = 1,965.0 metres.
Five gaps lie beyond it: Radcliffe to Whitefield (2,121.2 m), Monsall to Victoria (2,516.3 m), Newhey to Shaw and Crompton (2,759.2 m), Derker to Shaw and Crompton (3,043.6 m) and Bury to Radcliffe (3,502.3 m). Take those five away and the mean falls to 857.3 metres while the median only slips to 788.8 metres.
At primary, learners round each gap to the nearest 100 metres and find the shortest and the longest. At Key Stage 3 they find the mean, median and range and argue about which to quote. At GCSE they draw the box plot, test for outliers and estimate from grouped data. At A level they ask why we used a great-circle formula rather than flat Pythagoras, and how much difference it makes over three kilometres.
The point at every stage is the same: an average is a choice, and a good mathematician says which one they chose and why.

A GCSE skill, checked
GCSE questions often hide the raw data and give only a grouped frequency table. Because we have all 101 gaps, we can see exactly how good the estimate is.
| Gap, metres | Frequency | Class midpoint | Midpoint × frequency |
|---|---|---|---|
| 0 to under 500 | 16 | 250 | 4,000 |
| 500 to under 1,000 | 51 | 750 | 38,250 |
| 1,000 to under 1,500 | 21 | 1,250 | 26,250 |
| 1,500 to under 2,000 | 8 | 1,750 | 14,000 |
| 2,000 to under 2,500 | 1 | 2,250 | 2,250 |
| 2,500 to under 3,000 | 2 | 2,750 | 5,500 |
| 3,000 to under 3,500 | 1 | 3,250 | 3,250 |
| 3,500 to under 4,000 | 1 | 3,750 | 3,750 |
The method every GCSE student learns: assume each gap sits at the middle of its class, multiply, add and divide. The products add to 97,250, and 97,250 ÷ 101 = 962.9 metres. The true mean is 952.9 metres, so the estimate is 10.0 metres too high, about 1%.
The modal class is 500 to under 1,000 metres, with 51 of the 101 gaps. The median falls in the same class: reading from a cumulative frequency graph, the estimate is 838.2 metres against a true median of 819.5.
Change the class width and the estimate changes. With 250 metre classes the estimated mean is 959.2 metres, only 6.2 too high. With 1,000 metre classes it is 905.9, which is 47.0 metres too low, because a wide class hides where its gaps really sit.
That is a lesson worth more than the formula: grouping throws information away, and the wider the groups, the more you throw away. Students who have seen it happen with real numbers stop treating an estimated mean as if it were exact.
All figures are Modern Age Coders' calculations from the OpenStreetMap download above. The table and the worked estimates are ours and are not taken from any exam paper.
Maths around Manchester
A lot of maths happens in Manchester outside any classroom of ours. We list it here because families ask; we run none of it and are linked to none of it.
The NCETM page says the lead school for the North West One Maths Hub is Altrincham Grammar School for Girls, and that the hub serves schools in Bury, Manchester, Oldham, Rochdale and Stockport. Maths Hubs work with teachers and schools, not with families directly.
The Department of Mathematics, in the Alan Turing Building, runs activities for school students. Its MathsBombe competition releases puzzles online: "Every fortnight a new chapter is released online consisting of two mathematical puzzles."
The department lists Taking Maths Further days, usually for groups of schools and mainly for Year 10; it says "There is no charge, and lunch is provided." A Mathematical Modelling Day for Year 12 is held in June.
The same department also runs The Alan Turing Cryptography Competition, and it says it will continue in 2026/27 as the northwestern partner for the mA*ths Online and Further mA*ths Online Programme for Year 12 and 13 students. Schools usually arrange places on these, so a learner who is interested should ask their maths teacher.
National challenges run alongside them. Our UK competitions calendar lists the UKMT challenges and others by age, and our olympiad page explains how we prepare learners for the harder rounds.
For a learner who enjoys puzzles, the Metrolink project above is a good warm-up for this kind of competition. It has no single right answer and rewards a clear explanation. In our lessons, a student who argues well for the median scores as highly as one who computes the mean correctly.
Our lessons are live on video, so a learner in Wythenshawe, Moston or Didsbury joins from home after school. Because we group by level rather than by postcode, a classmate might be logging in from Leeds or Bristol.

Maths for grown-ups
Plenty of the people who ask us about maths are adults. Many left school some time ago and want to understand what they were once only told to do.
A GCSE maths resit, or simply percentages, fractions and algebra from the start, at an adult pace and without the embarrassment of a classroom. Many adults find the reasons make sense now in a way they never did at fourteen.
Parents learn the methods their children are taught now, from the grid method to bar models, so homework at the kitchen table stops being an argument.
Spreadsheets, rates, statistics for reports, and the numbers behind data work. Our Functional Skills page and adult maths page say more.
Adults use the same Metrolink data as the teenagers, and often get more from it: anyone who has waited at a stop in the rain has an opinion on the gaps between them. The difference is that an adult tends to ask straight away whether the median is the fairer number to quote, which is exactly the right question.
A route through
The steps below are the order we teach in. A learner can join at any of them, and the free first lesson tells us which.
| Usually | Step | The sign it is secure |
|---|---|---|
| Years 3 and 4 | 1. Facts | Knows the tables to 12 × 12 and can rebuild one from another |
| Years 5 to 7 | 2. Methods | Multiplies, divides and works with fractions on paper, accurately and neatly |
| Years 8 to 10 | 3. Algebra and data | Writes a rule with letters and finds a mean, median and range from a table |
| Years 10 to 13 | 4. Judgement | Chooses an average or a model and explains, in words, why it fits the data |
A GCSE student who joins in Year 11 still gains a lot, as long as we fix the foundations first. A shaky understanding of fractions shows up everywhere from ratio to probability.
If the gap is larger than the time left before an exam, we will say so honestly at the free lesson.
The maths keeps going. Many learners move on to statistics and probability or to maths through coding, where the Metrolink distances become a short program.
Learners who enjoy problems for their own sake often try competition maths next.

Manchester maths questions
Maths tuition is teaching outside school hours that follows the learner rather than a class: it finds the gaps, explains the ideas behind them and builds confidence step by step. Ours is live and online, in small groups of five to ten at one level or one to one.
There is no single right age. We teach from 6, when number sense and times tables are being built, and we also teach adults up to 67. The useful moment is when a learner first feels lost, before the gap grows.
Yes. We teach to the national curriculum for England and to whichever board the school uses, AQA, Edexcel or OCR, at Foundation or Higher tier, or to IGCSE where that is the course.
Yes. We teach the tables to 12 × 12 so that each fact can be rebuilt from another, which makes them stick. The check is statutory in Year 4 at state-funded schools in England.
Both. Sixth formers can add Further Maths topics alongside A level Maths, and keen younger pupils can work on UKMT-style problems in our competition maths course.
The mean shares the total equally; the median is the middle value when the data are in order. In our Metrolink data the mean gap is 952.9 metres and the median 819.5, because a few long gaps pull the mean up.
No. All lessons are live on video with a real teacher, so a learner anywhere in the city joins from home.
No. We teach carefully and report honestly on progress, but no tutor can promise a grade, and we do not.
Yes. We teach the GCSE content again at an adult pace, from whichever topic feels weakest. The entry is made through a college or exam centre, and we have no link with the NCETM, any Maths Hub or the university.
Nothing for the trial lesson. Ongoing places cost USD 100 per month in a small group or USD 150 per month one to one, with no joining fee and no minimum term.
