Learn to code: write it, run it, make it better.

Ages 6 to 8: play and sequence

Block-style thinking: give a character steps, use loops and make choices. Code Jungle and Code Robot start here.

Ages 9 to 11: first Python

Print, variables, loops and if statements, using short programs you can change.

Ages 12 to 14: functions and projects

Functions, lists, dictionaries and puzzles such as primes, ciphers and binary search.

Ages 15 and up: algorithms and more

Sorting, searching, data structures, web development and competitive programming.

Code Jungle

Write Python to guide a monkey through 24 levels.

Code Robot

Give a robot commands to reach the goal.

Turtle Studio

Draw shapes and patterns with code.

Python practice

Small exercises with instant checking.

Predict the output

Read code and say what it prints.

HTML and CSS lab

Build and style a web page.

Sorting visualiser

Watch algorithms put numbers in order.

Pathfinding visualiser

See how a computer finds a route.

How the web works and your first HTML page

Complete the page: give it the title `My page`, put an `h1` heading inside the body, add two lines of text separated by `<br>`, and add an HTML comment.

Adding CSS: three ways and three selectors

Colour the `h1` text, give `.intro` a `background-color`, and give `#special` both a `color` and a `background-color`.

Responsive design and the 12-column grid

Inside a `div` with class `container`, build a `div` with class `row` that holds three `div` columns with class `col-md-4`, each containing an `h3` heading and a paragraph.

How fast is it? Counting steps

Write pair_checks(n): two nested loops that count every pair (i, j) with i smaller than j among n items, and return the count. The program prints pair_checks(10).

Euclid's shortcut

Write gcd_steps(a, b) returning (gcd, steps) where steps counts the remainder steps, and lcm(a, b). Print gcd_steps(48, 18) and lcm(4, 6).

Seeing the bits

Print each of 5, 12 and 255 as 8 binary digits, and write count_ones(n) that counts the 1 bits using & and >>.

Counting outcomes

Write ways(target), the number of dice pairs that add up to target, and as_fraction(top, bottom) that returns text like 1/6 in lowest terms. Print the chance of a total of 7.

Averages

Write mean(data), median(data) and mode(data). If several values tie for most common, mode returns the smallest of them. Print all three for the list.

Records, filters and rankings

Keep the students whose score is at least cutoff, sort them by highest score (ties by name), print how many qualified, and print the first top of them as a numbered list.

Your first drawing: a square

Use a for loop to draw a square with sides of 100.

Project: break the code

Write decode(text, shift) that undoes a shift code, and use it to read wkh txlfn eurzq ira (shift 3).

Project: a smiley factory

Write draw_smiley(x, y) that draws a gold face, two black eyes and a smile at that position, and call it three times at x = -120, 0 and 120.

Your first program

Make the program print exactly: Hello, world!

Putting values into text

Print Asha is 11 years old. using an f-string with the variables name and age.

Asking a question with if

If temperature is above 30 print Hot day.

Repeating with for

Print the numbers 1 to 5, one per line.

Lists: many values in one

Print the first pet, the last pet, and how many pets there are.

Functions: your own instructions

Write a function called cheer that prints Hip hip hooray! and call it twice.

Learn HTML

HTML is the language that builds every web page. Type a little code, watch the page appear next to it, and get a tick when you have it right.

Learn CSS

CSS makes a web page look good. The page is already written; you write the style rules and watch it change as you type.

Learn JavaScript

JavaScript makes pages do things. Write a few lines, press Run, and see what your program prints. The lessons start from nothing.

Hello world and variables

Print a message, store things in variables and join them together.

Times table printer

Print the seven times table with a loop.

Even or odd

Say whether each number from 1 to 10 is even or odd.

FizzBuzz

Count from 1 to 20. For multiples of 3 print Fizz, for multiples of 5 print Buzz, and for both print FizzBuzz.

Add up the numbers 1 to 100

Add 1 + 2 + 3 + ... + 100, and check the answer with a formula.

Countdown

Count down from 10 and finish with a message.
