Coding classes in Tower Hamlets

What are the best coding classes in Tower Hamlets?

Tower Hamlets is the east London borough of Canary Wharf, Whitechapel, Bow, Bethnal Green, Poplar, Limehouse, Stepney and the Isle of Dogs, with 310,306 residents at the 2021 Census and the White Tower of the Tower of London inside its boundary. The coding classes that stick teach one idea so deeply a learner can reuse it everywhere, and this page does it with recursion: the Tower of Hanoi, a puzzle solved by a function that calls itself, whose 64-disc version would need more moves than there are seconds in hundreds of billions of years. Everything is taught live on video by our teachers in India, to anyone from six to sixty-seven, alone or alongside five to nine classmates at the same stage. Lesson one is free; a class seat then costs USD 100 each month and private tuition USD 150 each month.

The Tower of London's White Tower, its curtain walls and its chapel are all Grade I entries on Historic England's list, and all stand inside Tower Hamlets. Our learners borrow the name for a very different tower. The Tower of Hanoi is a stack of discs on one of three pegs, largest at the bottom. Move the whole stack to another peg, one disc at a time, never putting a bigger disc on a smaller one. With three discs it takes seven moves; with ten, 1,023. The solution is the classic example of recursion: to move ten discs, move nine out of the way, move the biggest, then move the nine back on top. Learners write that in a few lines, count the moves, time their computer, and discover a hidden pattern shared with the binary counting used in digital sensors.

Facts last verified 25 September 2026. Teaching is online; no Tower Hamlets branch is claimed.

Course picks for Tower Hamlets

First courses in Tower Hamlets

Imagine a Year 1 child in Bow who stacks everything into towers, a Year 8 pupil in Whitechapel who enjoys logic puzzles, a Year 12 student in Poplar planning to study computer science, and an office worker at Canary Wharf who has heard of recursion but never quite trusted it. All four can start with a free lesson.

The Tower

The White Tower, the inner and outer curtain walls with their mural towers, the Middle Tower and the Chapel of St Peter ad Vincula are all Grade I.

East End churches

Christ Church, the churches of St George in the East, St Anne and St Dunstan and All Saints, and St John on Bethnal Green are among the other Grade I entries.

Docks and almshouses

Warehouses, quay walls and Blackwall Basin from the old docks are Grade I, as are the Trinity Green almshouses and chapel.

Tower Hamlets calls its libraries Idea Stores; the service's website names Idea Stores at Bow, Canary Wharf, Chrisp Street, Watney Market and Whitechapel.

The puzzle

Three pegs, a stack of discs, one rule

The moves needed double, plus one, with every disc you add. Learners find the pattern by counting small cases before any theory.

Moves needed for each number of discs, checked by our program
DiscsMovesAs a formula
112 - 1
378 - 1
101,0231,024 - 1
201,048,575about a million
6418,446,744,073,709,551,6152 to the power 64, minus 1

Each extra disc doubles the work and adds one, because you must move everything above it twice. Twenty discs need just over a million moves. Sixty-four need more than eighteen quintillion. The pattern is exact, so learners can check the formula against every run of their program, and it is the clearest possible picture of exponential growth: small at first, then impossible.

Signature project

Recursion, a stopwatch, and a hidden binary pattern

Learners write the recursive solver, time it, then find a second, surprising way to generate exactly the same moves.

1. A function that calls itself

To move n discs from A to C: move n minus 1 discs to B, move the biggest to C, move the n minus 1 from B to C. Zero discs means do nothing. That is the whole program.

2. Time it

On our computer Python produced 4,194,303 moves for 22 discs in about one second: roughly four million moves a second.

3. Find the pattern

List which disc moves at each step: 1, 2, 1, 3, 1, 2, 1, 4. It is the same sequence as the bit that flips in a binary reflected Gray code.

How long a 64-disc tower would take, run 25 September 2026
SpeedTime for 2 to the 64, minus 1, moves
One move a second, by handabout 585 billion years
Our computer, about 4 million moves a secondabout 145,000 years

Both times are extrapolations, calculated rather than run, and learners are asked to show the arithmetic. The Gray code discovery is the surprise. In a Gray code, counting from one number to the next changes exactly one binary digit. For all 1,023 moves of a ten-disc tower, the disc moved at each step is exactly the digit that changes in the Gray code, and also one more than the number of zeros at the end of the step number written in binary. Disc 1 moves every other time, 512 times in all; the largest disc moves once.

Why this beats asking an AI to solve it

An AI assistant can print a Tower of Hanoi solver instantly. What it cannot give a learner is the moment recursion clicks: trusting a function to solve the smaller problem before it has finished solving the bigger one. Learners who reach that moment, then time their code and find the Gray code hiding in the output, understand recursion, exponential growth and binary at once, and can reason about why some problems are hopeless even for the fastest machines.

Why Gray codes matter

Counting where only one digit changes

Gray codes are not just a puzzle curiosity. They solve a real engineering problem.

Ordinary binary

Going from 3 (011) to 4 (100) flips three digits at once. If a sensor reads them a split second apart, it can briefly report nonsense.

Gray code

In a Gray code, neighbouring numbers differ in one digit only: 000, 001, 011, 010, 110, 111, 101, 100.

One formula

The Gray code of k is k combined bit by bit with k shifted right once. Learners code it in a single line and check it against the Hanoi moves.

GCSE computer science students meet binary and can follow the doubling pattern; A-level students study recursion formally and can prove the move count by induction. The list entries are Historic England's; every count, timing and Gray code check on this page was produced by our own program on 25 September 2026, and other computers will give different speeds. Historic England, Tower Hamlets Council, the Idea Store service, TfL and the ONS have no connection with Modern Age Coders.

Getting around

Whitechapel's four lines, and a quiet desk

Tower Hamlets is threaded with Underground, Elizabeth line, DLR and Overground routes. A lesson with us needs none of them.

Whitechapel

TfL's open data lists the District, Hammersmith & City, Elizabeth and Windrush lines at Whitechapel.

Isle of Dogs to Bow

A learner at the southern tip of the Isle of Dogs and one in Bow can be in the same class from home.

One step at a time

Like the discs, learners move up one stage at a time, in groups of five to ten at the same level.

Coding and AI

AI can write recursive code. Why should a Tower Hamlets teenager learn to think recursively?

Because recursion is a way of thinking, and thinking is what you bring to the tools.

AI assistants write recursive functions readily. Understanding them is another matter: why the function can trust itself, where it stops, and how fast its work grows. A learner who has written the Tower of Hanoi solver, watched a 22-disc run take a second and calculated that 64 discs would take 145,000 years on the same machine, understands exponential growth in a way that protects them from impossible plans, whether a human or an AI proposes them.

Recursion appears in file systems, search, parsing and many AI methods. Learning it through a physical puzzle makes it stick. Code generators will keep getting quicker, and the people who can judge the size of a problem before starting will stay in demand.

Tower Hamlets has stood guard over the Thames for nearly a thousand years. A learner here who can reason about a tower of discs that would outlast the stars has a lasting skill of their own. The longer argument is in why teenagers should still learn to code in 2026.

FAQ

Tower Hamlets questions

About the borough, the Tower of Hanoi project and our lessons.

How many people live in Tower Hamlets?

The 2021 Census counted 310,306 usual residents in the London Borough of Tower Hamlets, in ONS table TS001.

Is the Tower of London in Tower Hamlets?

Yes. Historic England's list entries for the White Tower, the inner and outer curtain walls, the Middle Tower and the Chapel of St Peter ad Vincula, all Grade I, fall inside the borough's boundary.

How many moves does the Tower of Hanoi need?

For n discs, 2 to the power n, minus 1. Three discs need 7 moves, ten need 1,023 and sixty-four need 18,446,744,073,709,551,615.

What is recursion?

Solving a problem by using a smaller version of the same problem. To move n discs, the program moves n minus 1 discs, moves the largest, then moves the n minus 1 again, stopping when there are no discs left.

What is a Gray code?

A way of counting in binary where each number differs from the next in only one digit. The digit that changes at each step matches exactly which disc moves in the Tower of Hanoi solution.

When would lessons be?

The free session tells the teacher where the learner stands; we then propose a class at that stage with a seat, meeting on a fixed evening that we always express in UK time.

What does a learner need?

A computer with sound and a reliable connection. The recursion project needs only Python.

Is there a Modern Age Coders centre in Tower Hamlets?

No. There is no Tower Hamlets centre and no premises anywhere in the UK, because every lesson is live online. A learner needs a computer with sound and a stable connection, and our phone number is Indian.

What do coding classes in Tower Hamlets cost?

The first lesson is free. After that, a group place costs USD 100 a month for two live lessons a week, about eight a month, with five to ten learners, and one-to-one teaching on the same timetable costs USD 150 a month. Nothing is charged until the course, format and time are agreed.

How are the groups made up?

By level, pace and goals rather than by age or neighbourhood, with five to ten learners at one stage. Where no group fits the learner's week, one-to-one lessons are offered.
