The town list uses ONS built-up areas from that count. | Place | People | Place | People | | --- | --- | --- | --- | | Connah's Quay | 16,770 | Broughton | 6,530 | | Hawarden | 14,280 | Shotton | 6,500 | | Buckley | 13,560 | Bagillt | 5,945 | | Flint | 12,780 | Mynydd Isa | 4,735 | | Mold | 9,890 | | | | Holywell | 7,735 | | | Two built-up areas cross the county boundary and are left out: about 5,140 people inside Flintshire belong to the Chester built-up area, and most of Hope's 4,420 live on the Flintshire side. Penyffordd is next in size after the table. Flintshire pupils learn under the Curriculum for Wales and sit WJEC papers at GCSE and A level. Flintshire County Council sets school terms; we have not read them, so families share their own dates. ### Wrexham and WJEC exams The city of [Wrexham](/best-coding-class-in-wrexham) has its own page. For exam help: [WJEC GCSE Computer Science](/wjec-gcse-computer-science-help-wales) and [WJEC GCSE Digital Technology](/wjec-gcse-digital-technology-help-wales). The Flintshire project ## Thirteen digits, twelve drawn Stripes of seven, three code tables, and a hidden digit. The number is invented, not a real book. The learner takes twelve digits starting 978, adds a thirteenth check digit using the standard sum with weights of one and three, and gets 9780000000019. Then comes the barcode. Each drawn digit becomes a pattern of seven narrow stripes, dark or light, written in Python as ones and zeros. There are three pattern tables, called L, G and R. The right-hand six digits always use R. The left-hand six use a mixture of L and G, and here is the trick: the choice of L or G for those six digits spells out the first digit. For a first digit of 9, the left six follow the pattern L, G, G, L, G, L. | Part | What it holds | Stripes | | --- | --- | --- | | Start guard | A fixed pattern so the scanner can find the edge | 3 | | Left six digits | Each in L or G code; the L/G mix encodes the first digit | 42 | | Centre guard | A fixed pattern in the middle | 5 | | Right six digits | Each in R code, including the check digit | 42 | | End guard | The same as the start | 3 | | Total | Thirteen digits carried by twelve drawn ones | 95 | How can a scanner tell an L pattern from a G pattern? The learner counts the dark stripes: every L code has an odd number, every G code an even number. So a scanner reads the six left-hand digits, notes odd or even for each, and looks up the first digit from that pattern of six. The program decodes its own barcode and gets back 9780000000019. Read backwards, the patterns do not match the tables, so our decoder refuses it rather than returning a wrong number. Then the learner damages the barcode on purpose, flipping one stripe at a time, all 95 of them. Every single-stripe error is caught by the patterns themselves, because a flipped stripe changes the odd-or-even count or produces a pattern in no table, so the check digit is not even needed for these. It is a neat demonstration that careful design, not luck, lets a scanner say "I cannot read that" instead of guessing. ### Ages 8 to 11 Draw a barcode on squared paper from a code table, swap with a friend, and decode each other's. ### Ages 11 to 15 Write Python that turns digits into stripes of ones and zeros and prints a barcode as text. ### Ages 15 and up Build the full encoder and decoder, hide the first digit in the L/G pattern, and test every single-stripe error. ### A real library, an invented number The library's history comes from Cadw's record. The barcode number is invented and belongs to no real book, and nothing here describes the library's own catalogue or systems. Why Hawarden's library ## Gladstone's gift of 25,000 books What Cadw's record says about the building. | Record detail | What it says | | --- | --- | | Founded | 1890, by W. E. Gladstone | | Books | Some 25,000 of his own books, first lodged in a temporary building on the site | | Library wing | Built 1899 to 1902 as part of the National Gladstone Memorial | | Architects | Douglas and Minshull of Chester | | Later addition | An accommodation wing, 1904 to 1906 | | Materials | Red sandstone under a medium-pitched slate roof | Barcodes are one of the most successful pieces of everyday computing: they sit on groceries, parcels, tickets and library books, and the same ideas of fixed-width patterns, guard marks and built-in error detection reappear in QR codes, network packets and storage formats. A Flintshire pupil who has hidden a digit in odd and even stripes understands how clever encoding makes machines reliable. We have no connection with Cadw, the library or Flintshire County Council. Cadw wrote the record; we wrote the barcode program and chose the invented number, so any slips are ours. Learning path ## From secret codes to data formats Year bands are guides; the trial lesson finds the right level. Years 1 to 4 ### Codes and patterns Block coding with secret messages and simple patterns. [Coding for Kids](/courses/kids-coding-blocks-masterclass)[Scratch Coding for Kids](/courses/scratch-programming-complete-course)Years 5 to 8 ### Ones and zeros Typed Python with binary, strings and lookup tables. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Years 9 to 13 ### Encoding and testing Data representation and systematic testing alongside WJEC GCSE and A level Computer Science. [Python for Teens](/courses/python-complete-masterclass-teens)[Problem Solving for Teens](/courses/problem-solving-dsa-masterclass-teens)Adults ### Real formats Python for adults working with barcodes, files and data standards. [Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)AI and formats ## An AI can write a barcode generator in seconds. Will it test the damaged cases? A generator that works on one example is not yet a reliable encoder. Ask a chatbot for EAN-13 code and it will usually produce something that draws a plausible barcode. Whether it handles the hidden first digit correctly, rejects a backwards read, and catches a damaged stripe is only known after systematic tests. A Flintshire learner who has flipped all 95 stripes one by one knows how to test a format properly. That habit is what turns AI-written code into code other people can depend on. Breaking your own code on purpose, every way you can, is a habit worth learning, and a reason Flintshire teenagers should code in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How lessons run ## From Holywell to Penyffordd, lessons at home Every town and village in the county joins by video. ### Hands on, from the start Pupils build every program themselves, and the teacher, watching the shared screen, steps in only when a nudge will help. ### Fitted to Welsh schooling We match Shotton Year 5s and Buckley sixth-formers alike to their school year and Curriculum for Wales stage, and follow WJEC for exams. Lessons are in English. ### A free first lesson One complete lesson without charge, then honest advice. ### Groups at one level Five to ten learners at the same level, joining from many places. ### Term-time lessons Two lessons weekly in term, with holidays off. ### Same hour, all year British summer time or not, the lesson stays put at its UK hour; teachers working on India time adjust. Why groups span towns Five learners at one level, free at the same time, rarely live in one Flintshire town. Grouping by level gives a pupil in Bagillt or Mynydd Isa a class that fits. Fees ## Fees in Flintshire Mold or Connah's Quay, the fee is identical, the same as in every country we teach outside India. First class**USD 0** A complete lesson, free, followed by a recommendation. Group tuition**USD 100** About eight lessons a month in a group of five to ten. Private tuition**USD 150** About eight lessons a month, one-to-one. Fees are in US dollars; there is no sterling list. We start billing only after the free lesson has fixed a course and weekly time; the pricing page explains holidays, missed lessons and switching formats.
