That spread of ages shows up in our classes. A Year 4 child in Plympton might be building a first Scratch game, a Year 12 student in Mutley studying A level Computer Science, and an adult in Devonport learning Python to handle spreadsheets at work, each in a small group of learners at a matching level. Stone that moved ## A lighthouse brought ashore and a victualling yard in granite From The Box, which looks after Smeaton's Tower, and from Royal William Yard's own history. ### 1759 Smeaton's Tower was first built on the Eddystone reef, out in the Channel. In the early 1880s it was found that the sea was eroding the rock beneath it, and it was taken down. ### Stone by stone The Box says about two thirds of the lighthouse was moved, one stone at a time, to Plymouth Hoe, where it now stands 72 foot high with its lantern room restored. ### 1825 Royal William Yard, designed by Sir John Rennie and named after King William IV, began supplying the Royal Navy with food and drink and did so for over a century. We have no connection with The Box or Royal William Yard. Both belong here because they are a large part of why Plymouth's historic buildings sit where they do. Of the city's 22 Grade I list entries, nine are in Royal William Yard alone, which its owners describe as Europe's largest collection of Grade I listed military buildings. A map of listed buildings is partly a map of the navy. Where the points come from Historic England publishes the National Heritage List for England as open data under the Open Government Licence, with a grid reference for every listed building entry. Clipped to the Plymouth boundary it gives 782 entries: 669 at Grade II, 91 at Grade II* and 22 at Grade I. One entry can cover a whole terrace or a long wall, so the counts are entries, not buildings. Signature project ## Plymouth's listed buildings as a density map A kernel density estimate replaces each point with a smooth bump and sums them. The one decision that matters is how wide the bumps are. | Bandwidth | Peaks | What the map shows | | --- | --- | --- | | 75 m | 62 | Almost every cluster of a few entries becomes its own peak | | 175 m | 24 | Peaks in 11 wards, the Barbican, Stoke, Devonport and Plympton among them | | 300 m | 12 | Neighbouring clusters begin to merge | | 600 m | 7 | Fewer, broader hills, with the small clusters gone | | 736 m, the rule of thumb | 4 | Only four wards keep a peak, and Devonport is not one of them | | 1,500 m | 2 | One hill over the city centre and one over Plympton | ### 1. Try a grid first Count entries in one-kilometre squares. Slide the grid 500 metres east and north and the busiest square jumps from 109 entries to 170, with no change to the data. ### 2. Swap squares for bumps Place a Gaussian bump over each entry and add them on a 50-metre lattice. The map no longer depends on where a grid begins, only on the bump width. ### 3. Let the data choose Leave one entry out, ask how likely the map built from the rest makes it, and repeat for all 782. The width with the highest score is 175 metres. ### The rule of thumb that erased a district A common shortcut sets the bandwidth from the spread of the points. For Plymouth it gives 736 metres, four times the cross-validated width, because the entries are spread over a long, narrow city. At that width Devonport, with 104 list entries and the second-largest count of any ward, has no peak of its own and melts into the slope running down from the Barbican. At 175 metres the tallest peak, about 388 entries per square kilometre, sits near Southside Street on the Barbican, and the second, about 242, near Fore Street in Plympton. The ward with the most entries, St Peter and the Waterfront, holds 305 of the 782. Those are the numbers a learner can defend, because the width that produced them was tested rather than assumed. Smoothing with care ## Five checks before trusting a heat map Practised on listed buildings, then applied to open data of every kind: bus stops, trees, sensor readings, shop visits and the density plots inside data science notebooks. | Check | On the Plymouth map | What it catches | | --- | --- | --- | | Move the grid | The busiest square changes from 109 to 170 entries | A hotspot that is only an accident of where the lines fall | | Vary the width | Peaks fall from 62 to 2 as the width grows | A story that depends on one unexamined setting | | Cross-validate | Leave-one-out scoring picks 175 metres | A width chosen because it looked nice | | Know the unit | Counts are list entries, and one entry can be a terrace | Mistaking a record for a building | | Watch the edges | Bumps near the coast spill onto the sea | Density claimed where nothing can stand | The last check matters on a coastline. A bump centred on a quay spreads half its weight over Plymouth Sound, so densities along the water are understated and some density sits on the sea. Learners fix it the simple way, by reporting peaks rather than totals near the shore, and then read about the corrections statisticians use. ### Younger learners Dots of paint dropped on a map, blurred with a sponge, and the discovery that a wide sponge hides the small clusters. ### Teenagers The heritage list clipped to Plymouth in Python, a density map written by hand, and the bandwidth chosen by cross-validation. ### Adults Density plots in analysis tools at work, with the bandwidth reported and justified instead of left at its default. We are not connected with Historic England, The Box, Royal William Yard or Plymouth City Council. The heritage list and ward boundaries are open data under the Open Government Licence and the census tables are public; the density maps, peaks and cross-validation are our own analysis. Learning ladder ## From paint dots to a cross-validated map The age bands give a rough idea only; the free lesson finds the right first step. Ages 6 to 10 ### Dots and blurs Plotting points on a simple map, counting them in squares, and seeing how moving the squares changes the count. [Scratch Coding for Kids](/courses/scratch-programming-complete-course)[Elementary Maths for Grades 1-5](/courses/elementary-mathematics-complete-masterclass)Ages 11 to 13 ### Histograms Drawing bar charts from lists of numbers in code and noticing that the bar width changes the picture. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Ages 14 to 18 ### Density maps in Python Gaussian kernels, a lattice of grid points and leave-one-out cross-validation on real open data. [Data Science for Teens](/courses/data-science-course-for-teens-python-data)[High School Mathematics](/courses/complete-high-school-mathematics-mastery)Ages 18 to 67 ### Estimating distributions Kernel density, smoothing choices and clear reporting for adults analysing data in their work. [Statistics & Probability](/courses/statistics-probability-maths-course)[Data Science Course](/courses/data-science-complete-masterclass-college)Coding and AI ## A plotting library draws a density map by default. Why should a Plymouth teenager choose the bandwidth? Because the default made Devonport vanish, and nobody would have noticed. Ask an AI assistant for a heat map of these points and it will produce one in seconds, usually with a bandwidth picked by a rule of thumb. The picture will look authoritative. A learner who has tried several widths and scored them knows that the same 782 points can show four peaks or twenty-four, and knows how to decide which to believe. Machine learning is full of the same trade. Every model has a setting that controls how smooth or how detailed it is allowed to be, and cross-validation is the standard way to choose it without fooling yourself. Kernel density is one of the clearest places to see that idea at work, because the effect of the choice is visible on a map of streets the learner knows. So a Plymouth teenager should still learn to program in 2026, in a city that moved a lighthouse ashore stone by stone: software makes the map instantly, but deciding how much detail it is allowed to keep is still a human judgement. The longer argument is in [why coding is worth learning in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Stoke, Plymstock or Southway, from home Crossing Plymouth at the end of a school day takes time, and a live online lesson simply removes the journey. ### Either side of the Plym A learner in Plymstock and another in St Budeaux can join the same lesson without anyone crossing the river. ### Reception to A level Reception, Key Stages 1 to 4, GCSE options and A levels, named as Plymouth schools name them, with all teaching in English. ### A lesson, not a pitch The free session teaches a real piece of work, then suggests a level, a course and a weekly slot. There is nothing to pay and no card to enter. ### Grouped by stage Five to ten learners at the same level, drawn from Plymouth, other parts of Britain and abroad, so each stage has a time that suits. ### A steady rhythm Two regular lessons a week, roughly eight a month, with half terms and exam periods arranged with the teacher beforehand. ### Clocks that do not move India keeps the same time all year, four and a half hours ahead of Plymouth during British Summer Time and five and a half in winter, so UK afternoon and evening lessons stay within the teaching day. Across the Tamar and beyond Families in Saltash, Ivybridge, Tavistock or Torpoint join the very same classes, because groups are built around level and every lesson happens online. Fees ## Plymouth lesson fees The first lesson is free, and then there is one monthly fee. First class**USD 0** A whole lesson at no charge, closing with a suggested level, course and weekly time. Group tuition**USD 100** Roughly eight live lessons a month in a class of five to ten learners at one level. Private tuition**USD 150** Roughly eight live lessons a month, with the teacher focused on your learner alone. Outside India every family pays one US dollar fee, so Mannamead and Efford pay the same, and no prices are shown in pounds. We take no payment until the free lesson has settled a course and a slot; details on pausing, missed lessons and changing between group and private teaching are on the pricing page.

Census 2021 recorded 264,695 usual residents in the Plymouth council area: 257,494 living in households and 7,201 in communal establishments such as halls of residence and care homes. ### How does Plymouth compare with England? In 2021, 8.0% of residents were aged 20 to 24 against 6.0% for England, 21.8% of residents aged five and over were students against 20.4%, and there were 3,314.8 residents per square kilometre against 433.5. ### What is kernel density estimation? A way of turning a set of points into a smooth map of where they are concentrated, by placing a small bump over each point and adding the bumps together. The bump width, called the bandwidth, controls how much detail survives. ### Why does the bandwidth matter so much? On Plymouth's 782 listed building entries, a 175-metre width shows 24 peaks and a 736-metre width shows four, losing Devonport entirely. Cross-validation chose 175 metres as the width that most accurately predicts entries left out. ### Where does the listed building data come from? Historic England's National Heritage List for England, published as open data under the Open Government Licence. Inside the Plymouth boundary it has 782 entries, 22 of them Grade I. ### What is the story of Smeaton's Tower? The Box says it was built on the Eddystone reef in 1759, taken down in the early 1880s because the sea was eroding the rock beneath it, and largely rebuilt on Plymouth Hoe. We are not connected with The Box. ### What times are Plymouth lessons? Weekday afternoons and evenings or weekends, at a UK time chosen during the free lesson. India is four and a half hours ahead of Plymouth in summer and five and a half hours ahead in winter. ### Is there a Modern Age Coders centre in Plymouth? No. There is no Plymouth centre and we have no premises anywhere in the UK; all lessons are live online. Learners need a computer with working sound and a stable connection, and our phone number is Indian. ### How much do Plymouth lessons cost? The first lesson is free. After it, a group place costs USD 100 a month for two live lessons a week, about eight a month, in a group of five to ten, and one-to-one lessons on the same pattern cost USD 150 a month. Course, format and time are agreed before anything is charged. ### How are Plymouth groups arranged? By level, pace and aims rather than age or where a family lives, with five to ten learners at one stage. When no group fits the learner's week, we offer one-to-one lessons.
