Beyond the Bolton built-up area itself, the ONS lists Farnworth at 28,760, Westhoughton at 21,960 and Horwich at 20,700, all inside the borough. Children here follow the national curriculum for England, and lessons pause whenever your school breaks up. ### Wider area Our [Greater Manchester](/coding-classes-in-greater-manchester) page covers the county, and the [North West](/coding-and-ai-classes-in-north-west-england) page gathers the region. The Bolton project ## Pricing Crompton's yarn by length A count is a backwards unit, and the program has to respect that. Daniels's book gives the definition in passing: counts are "hanks in the pound". So 40's means 40 hanks weigh one pound, and 60's means 60 hanks weigh one pound. The learner first converts the prices into pence, at 12 pence to the shilling: 14 shillings is 168d and 25 shillings is 300d. Per pound, the fine yarn costs 300 / 168, or 1.79 times as much. That is the number most people stop at. | Yarn | Price per pound | Hanks per pound | Price per hank | | --- | --- | --- | --- | | 40's | 14s (168d) | 40 | 4.2d | | 60's | 25s (300d) | 60 | 5.0d | | Ratio, fine to coarse | 1.79 times | 1.5 times | 1.19 times | But a weaver buys thread to cover cloth, and cloth is measured by length. Dividing each price by its count gives the price per hank: 4.2d for 40's and 5.0d for 60's. Measured by length, Crompton's finer yarn cost only about 19 per cent more, even though a pound of it cost 79 per cent more. The program prints both, labels each clearly, and the learner writes one sentence saying which comparison answers which question. The second trap is averaging. Blend 60 hanks of 40's with 60 hanks of 60's. The learner's first guess is a count of 50. The code weighs it instead: the 40's weighs 1.5 pounds, the 60's weighs 1 pound, so 120 hanks weigh 2.5 pounds, a count of 48. Averaging rates over equal lengths needs the harmonic mean, the same rule that governs average speed over equal distances. A test checks that the function returns 48, and another that an equal-weight blend correctly returns 50. ### Ages 8 to 11 Weigh equal lengths of thick and thin string on kitchen scales and count how many fit a fixed weight. ### Ages 11 to 15 Write price_per_hank() in Python and compare it with the price per pound. ### Ages 15 and up Write blend_count() for any mix and prove when it equals the harmonic mean. ### Daniels's numbers, our arithmetic Crompton's prices and the definition of a count are quoted from The early English cotton industry by George W. Daniels, on Project Gutenberg. The conversions, the comparison and the blend calculation are ours. Why Crompton ## From Firwood Fold to the mule Dates and details from Daniels's chapter on the mule. | What | According to the book | | --- | --- | | Birth | 3 December 1753, at Firwood Fold in the township of Tonge | | Childhood home | Hall-i'-th'-Wood, from about the age of five | | First efforts | From 1772, to make better yarn for his own weaving | | The machine | Begun in 1778, first called the Hall-i'-th' Wood Wheel or Muslin Wheel | | Completed | 1779 | | What it did better | Spun thinner yarn, of higher counts, than earlier machines | Indirect units like the yarn count are everywhere in computing. Screen resolution is quoted as pixels per inch, fuel economy as miles per gallon rather than gallons per mile, and data rates as bits per second. Every time a program averages one of these, it has to decide whether an arithmetic or harmonic mean fits. A Bolton learner who has priced Crompton's yarn correctly will ask that question automatically. Modern Age Coders has no connection with Project Gutenberg or the ONS. The book and the census data are theirs; the code, and any error in it, is ours. Steps by school year ## From string on scales to data science Years are a guide only; the trial settles the level. Years 1 to 4 ### Patterns and loops Block coding with repeating patterns and simple games. [Coding for Kids](/courses/kids-coding-blocks-masterclass)[Scratch Coding for Kids](/courses/scratch-programming-complete-course)Years 5 to 8 ### Python and units First Python programs, measurements and conversions. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Years 9 to 13 ### Data and AI Averages, data and AI projects, beside GCSE and A level. [Python for Teens](/courses/python-complete-masterclass-teens)[High School Mathematics](/courses/complete-high-school-mathematics-mastery)Adults ### Practical programming Python and data analysis for adult learners. [Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)AI and averages ## Does an AI know which average to take? A mean is only right if it matches the question. Give a chatbot two yarn counts and ask for the blend, and it may simply add and halve. The answer sounds sure of itself, and it can be wrong in exactly the way Crompton's customers would have noticed. A Bolton learner who has written blend_count() knows to ask what is being held equal before trusting any average. Spotting the wrong average is one strong reason for Bolton teenagers to keep learning to code in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Running the lessons ## Farnworth to Horwich, one video link Every part of the borough joins the same way. ### The student drives Every line is typed by the learner, while the tutor reads along and prompts with questions. ### Pitched to the year Year 3 or Year 11, each learner begins where their year and trial point, and we use the right exam board. ### No-cost trial The opening lesson is free, followed by honest advice on what suits. ### Same-stage classes Five to ten learners at one level, gathered from across the UK. ### Weekly rhythm Two lessons a week in term time, with school holidays kept clear. ### Steady time slot Clock changes in spring and autumn are absorbed by our teachers; your time stays the same. Why classes happen online Five Bolton learners at one stage who are all free on the same evening seldom share a street. Online, everyone gets a class that fits. Fees ## Fees for Bolton learners Bolton families pay what every family outside India pays. First class**USD 0** A complete lesson at no charge, with a recommendation at the end. Group tuition**USD 100** About eight live lessons per month in a small class. Private tuition**USD 150** About eight live lessons per month, one-to-one. All fees are in US dollars; we do not bill in sterling.

Submitted details are used for placement and follow-up. FAQ ## Bolton questions answered The town, the yarn project and the practical side. ### How many people live in Bolton? The 2021 census counted 295,961 in Bolton borough and 184,090 in the Bolton built-up area. ### Are there online coding and Python classes for Bolton? Yes. We teach coding, Python, AI and maths live online to Bolton learners from age 6 to 67. ### What is the Samuel Crompton project? Learners use Crompton's own yarn prices to compare cost by weight and by length, and to calculate the count of a blended yarn. ### What does 40's yarn mean? It means 40 hanks weigh one pound; a higher count means thinner yarn. ### Where did Samuel Crompton invent the spinning mule? At Hall-i'-th'-Wood in Bolton, according to George W. Daniels, completing it in 1779. ### Do lessons happen in Bolton itself? No, they are live online, so Farnworth, Horwich, Westhoughton and the town centre are all covered. ### Can you help with GCSE and A level? Yes, in maths and computing, aimed at understanding; we do not promise grades. ### How old do learners need to be? Between 6 and 67, and adults are welcome. ### What does it cost? Nothing for the first lesson, then USD 100 monthly for a group or USD 150 monthly for one-to-one. ### What happens in school holidays? Lessons pause. Send us the dates.
