Prologue - The Era When Coding Became Mandatory

By May 2026, coding is no longer optional. The UK introduced its Computing curriculum in 2014 and made it mandatory from age five, Korea mandated Software Education for middle school in 2018 and elementary 5-6 in 2019, and Japan added Programming Education to elementary schools in 2020, middle schools in 2021, and high schools in 2022.

Between those policy moves, the tools exploded. When MIT Scratch arrived in 2007, the very idea of children building their own games in class felt foreign. By 2026 it is normal for a five-year-old to make their first animation in Scratch Jr., publish a Roblox game at ten, and receive their first Devex payout at thirteen.

Then LLMs entered the room. Code.org strapped a chatbot named Kira onto its AI Lab so elementary students could train machine learning models. Roblox Studio shipped AI Code Assist that auto-generates Luau scripts. Tynker released AI Lesson Plans for teachers. Replit extended Code Mentor to teens.

Korea and Japan each grew their own standards. Korea consolidated around Entry from the Naver Connect Foundation, while Japan now leads with DeNA's Programming Zemi and Sony's Toio robots in schools. This guide threads every tool, every policy, and every safety question into a single narrative.

Chapter 1 - Why Kids Need to Code in 2026

Before the tools, the demand. There are four axes to children's coding in 2026.

- **Computational thinking** - Jeannette Wing proposed this in 2006 at CMU. Problem decomposition, pattern recognition, abstraction, algorithmic thinking. Coding is just the tool; the real target is the way of thinking.

- **AI literacy** - In 2024 Japan's MEXT (Ministry of Education) published an "AI Education Guideline" and Korea's Ministry of Education formalized a national AI standard for K-12 in 2025. The goal goes beyond using AI to understanding how it works.

- **Code as a creative medium** - Code is a means of self-expression. Mitchel Resnick (MIT, Scratch creator) emphasized the four Ps in "Lifelong Kindergarten": Projects, Passion, Peers, Play.

- **Labor market preparation** - Not direct vocational training, but computational thinking has soaked into every industry. Designers, marketers, accountants all need some coding fluency.

In an AI age, children's coding is less about training programmers and more about the gap between people who can build AI and people who can only consume it. Education exists to keep students from being stuck in the latter group.

[2026 Kids Coding Learning Curve - Five Stages]

Age 5-7 : Screenless coding, picture commands (Scratch Jr., Cubroid)

Age 8-10 : Block coding begins (Scratch 3.0, Entry, MakeCode)

Age 11-13 : Game creation (Roblox Studio, Minecraft Education, Tynker)

Age 14-16 : Text coding entry (Python, JavaScript, Swift Playgrounds)

Age 17-18 : Full development (Replit, GitHub, AI assistants)

Each stage uses different tools and demands different teacher roles. The 2026 challenge is how to bridge between stages.

Chapter 2 - Scratch 3.0 - The MIT Standard, 100 Million Projects

**Scratch** (scratch.mit.edu) was first published by the MIT Media Lab's Lifelong Kindergarten group in 2007. Scratch 3.0 launched in January 2019, abandoning Flash for HTML5 and WebGL.

- **Founder** - Professor Mitchel Resnick, a veteran of the 1980s Lego/Logo projects.

- **Language** - Block-based. Localized in over 70 languages including Korean and Japanese.

- **Cumulative projects** - Crossed 100 million in late 2025, with roughly 150,000 new projects per day.

- **Users** - Over 100 million registered, with 80 percent aged 8-16.

Scratch 3.0 brought two pivotal changes. First, Flash was dead, so the team rebuilt on WebAssembly and JavaScript. Second, it ran on tablets and iPads, where Scratch 2.0 could not.

Scratch follows a "low floor, wide walls, high ceiling" philosophy. You can make something in the first minute (low floor), span animation, games, music, and simulation (wide walls), and dig deep enough to build complex models (high ceiling).

The Extensions system enables external hardware integrations.

- **BBC micro:bit** - Connected via Scratch Link over BLE.

- **LEGO MINDSTORMS EV3 / SPIKE Prime** - Direct motor and sensor control.

- **Makey Makey** - The famous banana piano kit.

- **Translate + speech synthesis** - Google Translate API integration.

Scratch is free, ad-free, open source. The nonprofit Scratch Foundation runs on roughly USD 6 million per year, funded by Google, the LEGO Foundation, the MacArthur Foundation, and others.

Chapter 3 - Scratch Jr. - First Coding from Age Five

**ScratchJr** (scratchjr.org) is the preschool and early-elementary version of Scratch. It was released free for iPad and Android tablets in 2014.

- **Developers** - MIT Media Lab plus the Tufts DevTech lab (Professor Marina Bers) plus the Playful Invention Company.

- **Target age** - 5-7 years old.

- **Interface** - Coding with picture blocks only, no text.

- **No AI integration** - Deliberately kept simple.

ScratchJr is designed so that children who cannot yet read can still code. Every block is a pictographic icon. Kids move a cat character, record their own sounds, and even draw custom sprites.

Marina Bers argues in "Coding as a Playground" (2017) that the right metaphor for early coding is a playground: a space where there is no fixed right answer and exploration is free.

ScratchJr works fully offline once downloaded. There is no data collection or account signup. It satisfies COPPA (US under-13 privacy law), GDPR-K (EU), and Korea's Personal Information Protection Act for minors.

Chapter 4 - MakeCode - Microsoft's Classroom Weapon

**Microsoft MakeCode** (makecode.com) is Microsoft's block coding platform, created in 2016 for the BBC micro:bit.

- **Operator** - Microsoft Education and Research.

- **Editor modes** - Blocks, JavaScript, and Python (added 2024).

- **Target hardware** - micro:bit, Adafruit Circuit Playground, LEGO MINDSTORMS EV3, Minecraft, and Arcade.

MakeCode's distinguishing feature is the ability to flip the same program freely between Blocks, JavaScript, and Python. Students who start in Blocks experience a natural transition to text code on the same screen.

The main variants are:

- **MakeCode for micro:bit** - The board the BBC distributed free to one million UK 11-12 year olds. Built-in 25 LEDs, accelerometer, gyroscope, thermometer, and BLE.

- **MakeCode Arcade** - An 8-bit-style retro game console emulator. Hardware (Meowbit, GameGo) is sold separately.

- **MakeCode for Minecraft** - Block commands inside Minecraft Education Edition. Drive an NPC called the Agent to build and mine.

- **MakeCode for LEGO MINDSTORMS** - EV3 motors and sensors.

- **MakeCode for Circuit Playground** - Adafruit's round microcontroller.

micro:bit started in 2016 as a BBC project that handed one million boards free to every UK Year 7 student. As a result, micro:bit became the de facto school coding standard in the UK. Korea began adopting it in 2018, and Japan ramped up quickly after the 2020 elementary mandate.

Chapter 5 - Tynker - Bridging Blocks to JavaScript

**Tynker** (tynker.com) is a kids coding company founded in California in 2012. It was carved out of the BYJU'S group in 2025 and now operates independently.

- **Target age** - 7-14 years.

- **Editor modes** - Blocks, JavaScript, Python.

- **Content** - Licensed courses featuring Minecraft, Roblox, and LEGO characters.

- **AI Lesson Plans** (launched 2024) - Auto-generated lesson plans for teachers.

Tynker's strength is leveraging well-known IPs (Minecraft, LEGO, Barbie) for course content. Children stay motivated when they get to code with characters they already love.

Pricing (May 2026):

- Family plan around USD 20 per month.

- School plan roughly USD 6 per student per year.

- Some content is available free as a trial.

Tynker's "Mod Maker" lets children build mods for Minecraft Bedrock Edition. Outputs export as .mcaddon files that load into the actual game.

Chapter 6 - Code.org - Hour of Code and AI Lab

**Code.org** (code.org) is a nonprofit founded by Hadi Partovi in 2013, famous for the Hour of Code campaign and its "one hour of coding experience" slogan.

- **Hour of Code** - Held annually during Computer Science Education Week in December. Cumulative student participation has passed one billion.

- **Code Studio** - K-12 curriculum for every grade band.

- **AI Lab plus Kira** (launched 2024) - Machine learning training tool for elementary classrooms.

- **CS Discoveries / CS Principles** - Courses aligned with the US AP exams.

Code.org's strength is that the curriculum is structured around US K-12 grades. American teachers can teach and assess on the standard cadence.

**Code.org AI Lab** is the flagship feature launched in 2024. Students label text data, train ML models, and apply the results inside games, all through a block interface. Kira, a chatbot, plays the guide role.

The policy footprint is huge. Code.org lobbied all fifty US states to pass computer science education legislation or adopt standards, and all fifty now include CS in their K-12 standards.

Chapter 7 - MIT App Inventor - Mobile Apps Built by Kids

**MIT App Inventor** (appinventor.mit.edu) started at Google in 2010 and moved to MIT in 2012. It is a block-based Android app builder.

- **Founder** - Professor Hal Abelson at MIT, a veteran from the LISP and Logo eras.

- **Interface** - Block coding that ships Android apps.

- **Target age** - 12 and up.

- **AI features** (2023 onward) - TensorFlow Lite integration. Image classification models can be embedded in apps.

App Inventor is unusual because it produces real .apk files installable on Android phones. The output can be a working utility, not just a toy.

Notable App Inventor projects:

- An agricultural price information app in India.

- A maternal health app in Kenya.

- School timetable apps from US high schools.

App Inventor is free and open source. An iOS beta has existed since 2022 but is not as stable as Android.

Chapter 8 - Roblox Studio - Game Creation Standard and Youth Economy

**Roblox Studio** (roblox.com/create) is the game creation platform Roblox Corporation has run since 2006.

- **Language** - Luau, a variant of Lua.

- **Target age** - 13 and up (under 13 requires parental consent).

- **Users** - Over two million cumulative creators, around 70 million monthly active users.

- **AI Code Assist** (general availability 2024) - Generates code from comments.

Roblox Studio's game economy, **Devex (Developer Exchange)**, sets it apart from every other kids coding tool. Creators 13 and up can convert in-game Robux to USD. The rate is roughly USD 0.0035 per Robux as of May 2026.

Top Roblox creator earnings in 2024-2025:

- Adopt Me! (DreamCraft) crossed USD 100 million cumulative.

- Blox Fruits earned about USD 50 million.

- Brookhaven RP earned about USD 30 million.

- Multiple solo creators report annual income above USD 1 million.

**Roblox AI Code Assist** was announced at RDC (Roblox Developer Conference) 2023 and went GA in 2024. Example usage:

-- Make players jump in the air when they touch this red part

local part = script.Parent

part.Touched:Connect(function(hit)

local humanoid = hit.Parent:FindFirstChild("Humanoid")

if humanoid then

humanoid.JumpPower = 100

humanoid.Jump = true

end

end)

Type a single comment and the AI proposes Luau code. This is not simple autocomplete; the context awareness rivals GitHub Copilot.

The risks are real too. The BBC Panorama documentary in 2023 highlighted grooming risks on Roblox, and US congressional hearings in 2024 raised more safety concerns. Roblox responded with chat restrictions for under-13 accounts, age-gated voice chat, and stronger parental controls.

Chapter 9 - Minecraft Education - Microsoft's Classroom Tool

**Minecraft Education** (education.minecraft.net) is Microsoft's school-focused variant of Minecraft launched in 2016. It originated as a separate product, MinecraftEdu, which Microsoft acquired.

- **Pricing** - Around USD 5 per student per year as of 2026.

- **Editors** - MakeCode for Minecraft, Python, JavaScript.

- **Agent** - An NPC character controlled with code.

- **Curriculum** - Hour of Code content and grade-band lessons.

Minecraft Education's strength is pulling kids who already love the game into the classroom. Teachers get half of their motivation problem solved before they start.

Representative lessons include:

- **Code Builder** - Command the Agent to build a house in Blocks, JavaScript, or Python.

- **Chemistry Resource Pack** - Combine chemical elements inside the game.

- **Climate Futures** (introduced 2024) - Climate crisis simulation.

- **Biome Adventure** - Biome and ecology learning.

Minecraft Education is hard to use at home without an EDU license. Microsoft 365 EDU or a school license is required for full features.

Chapter 10 - Blockly - Google's Block Engine

**Blockly** (developers.google.com/blockly) is a block coding library Google open-sourced in 2012.

- **Type** - JavaScript library.

- **Used by** - Code.org, MIT App Inventor, MakeCode, and most other block coding tools.

- **License** - Apache 2.0.

- **Language transpilation** - Blocks compile to JavaScript, Python, PHP, Lua, or Dart.

Blockly itself is not an end-user product but a component embedded in other tools. Google Workspace for Education offers Blockly-based features, and "Blockly Games" (blockly.games) is a free mini-game collection.

Blockly's influence is large. Code.org, MakeCode, and App Inventor all use Blockly under the hood. Scratch maintains its own engine (Scratch Blocks then Scratch GUI), but the two ecosystems exchange ideas regularly.

Chapter 11 - EduBlocks - The Bridge from Blocks to Python

**EduBlocks** (edublocks.org) is a block-to-Python conversion tool developed in the UK. It is famously associated with Joshua Lowe, who started building it at age 13.

- **Target** - Ages 9-14, especially Python beginners.

- **Interface** - Scratch-style blocks alongside live Python code.

- **Pricing** - Free with no ads.

EduBlocks' core value is that drag-and-drop blocks generate Python code in a side pane simultaneously. Students watch blocks and text in parallel, easing the transition to plain text code.

It is widely used in the Raspberry Pi Foundation's free Code Club and CoderDojo networks, and the BBC micro:bit plus EduBlocks combination is also popular.

Chapter 12 - Entry - Korea's Standard Coding Tool

**Entry** (playentry.org) is a Korean kids coding platform run by the Naver Connect Foundation. It started in 2013 as a project at the KAIST School of Computing.

- **Operator** - Naver Connect Foundation (acquired in 2015).

- **Target age** - 8-15 years.

- **Languages** - Korean-optimized, partial English and Chinese support.

- **AI blocks** (2020 onward) - Speech recognition, image recognition, translation, text analysis.

Entry resembles Scratch closely but is specialized for the Korean school environment.

- **Korean textbook tie-in** - Examples appear directly in elementary 5-6 practical arts textbooks and middle school informatics textbooks.

- **AI blocks** - Naver Clova speech recognition and Clova OCR exposed as blocks.

- **Math blocks** - Elementary and middle school math concepts like fractions and coordinates as simulations.

- **Community** - Around 10 million registered users as of 2025.

Entry is free, optimized for Korean, and the most widely used coding tool in Korean schools. It is not data-compatible with Scratch, but the interface is similar enough that students can switch comfortably.

Chapter 13 - CodeMonkey - An Israeli Company That Settled in Korea

**CodeMonkey** (codemonkey.com) is an Israeli platform that launched in 2014. Its Korean subsidiary was set up in 2017.

- **Language** - A CoffeeScript-like simple text language transitioning to Python.

- **Game format** - Puzzles where a monkey is guided to a banana.

- **Korean presence** - Korea CodeMonkey (codemonkey.kr).

- **School adoption** - Around 1,500 Korean schools as of 2026.

CodeMonkey is distinctive because it starts with text from day one. There is no block phase; learners begin with simple function calls like `step 5` and `turn left`, then build complexity.

Pricing in Korea:

- Family plan around KRW 15,000 per month.

- School site licenses negotiated separately.

Chapter 14 - WiseShip, RoboRobo, and Hello Ruby - Korea's Coding Ecosystem

Beyond Entry and CodeMonkey, Korea's kids coding market includes a range of tools.

- **WiseShip** - Korean company offering blocks plus robot kits.

- **RoboRobo** - Founded in 1999, an elder of the Korean robotics and coding education market with its own RokIT robot kits.

- **Hello Ruby** - Linda Liukas's Finnish picture book series. Korean translations are published by Wisdom House. The series teaches computational thinking without code.

- **CodeyRocky** - A Makeblock (China) kids coding robot programmed with mBlock, a Scratch variant.

RoboRobo holds a significant share of the Korean cram school and after-school market. It packages physical computing curriculum with its robot kits and partners with several education offices.

Chapter 15 - Programming Zemi - DeNA's Japanese Standard

**Programming Zemi** (programmingzemi.com) is a kids coding app DeNA launched in 2017.

- **Target age** - 5-12 years.

- **Platforms** - iOS, Android, Windows.

- **Languages** - Japanese, English, Chinese, Korean.

Programming Zemi is a corporate social responsibility project from DeNA. The company distributes it free to schools in cooperation with municipalities like Saitama and Yokohama.

Features:

- **Tap-only operation** - Usable even without literacy.

- **Three modes** - Free creation, challenge, mini games.

- **Offline mode** - Fully usable without internet.

After Japan's MEXT mandated programming in elementary schools in 2020, Programming Zemi spread quickly thanks to its free pricing.

Chapter 16 - Viscuit, Springin', and Toio - Japan's Unique Tools

Japan has cultivated several distinctive kids coding tools.

- **Viscuit** - Developed in the late 1990s by Dr. Yasunari Wada at NTT Communication Science Laboratories. Children draw a picture and connect images with "megane" (glasses) to define behavior.

- **Springin'** - From Japanese company Shikinote. Kids draw, then attach sounds and motions to create interactive works. iOS and Android.

- **Toio** - A kids coding cube launched by Sony in 2019. The cube pairs with paper cards for a tactile interface.

- **embot** - A cardboard robot kit by NTT Docomo and Daiwa Securities. Build the chassis from cardboard, then control motors and LEDs with code.

- **UNCLE** - NHK Educational Channel's coding character for Japanese broadcasts.

Toio is especially interesting. Each cube contains motors and sensors and recognizes its position on a paper mat. Roll a cube through a maze or coordinate two cubes to paint a picture. The kit retails for around JPY 22,000.

Viscuit is recognized as an official education tool by MEXT and is reportedly used in about 30 percent of Japanese elementary schools.

Chapter 17 - Hardware Coding Kits - From micro:bit to LEGO

Physical computing kits push past screen-only coding into real-world interaction.

- **BBC micro:bit** - Started in 2016 by the BBC. Distributed free to every UK Year 7 student. School standard.

- **Raspberry Pi** - From the UK Cambridge foundation. A full Linux computer that boots from an SD card. Python and Scratch are the standards.

- **Arduino** - Italian origin. Microcontroller. Codable with mBlock, a Scratch variant.

- **LEGO MINDSTORMS Education / SPIKE Prime** - The LEGO education robotics line launched in 1998. EV3 was discontinued in 2024 and replaced by SPIKE Prime.

micro:bit hits the sweet spot of price (around USD 18) and capability for schools. It includes 25 LEDs, accelerometer, gyroscope, compass, thermometer, and BLE, and works with MakeCode, Python, and Scratch.

LEGO SPIKE Prime is simpler and more portable than EV3. Python support (via Pybricks or the official LEGO IDE) has strengthened, making it well suited for middle school.

Chapter 18 - Swift Playgrounds - Apple's iPad Coding School

**Swift Playgrounds** (apple.com/swift/playgrounds) is Apple's free iPad and Mac coding app, launched in 2016.

- **Language** - Swift, Apple's official language.

- **Platforms** - iPad and Mac.

- **No AI integration** - Deliberately simple.

- **App development** - From version 4 onward, you can ship to the App Store from iPad alone.

Swift Playgrounds 4 (2021) onward lets a kid build a SwiftUI app on iPad and publish it to the App Store. The entry barrier to releasing a first app dropped dramatically.

Features:

- **Learn to Code** - Beginner courses where commands move a 3D character.

- **Sandbox** - Free-form writing.

- **Augmented Reality** - ARKit integration samples.

- **Robot Programming** - Direct control of Sphero, LEGO MINDSTORMS, Dash, and Parrot drones.

Swift Playgrounds is free, ad-free, and collects minimal data. The downside is hardware cost: it requires an iPad or a Mac.

Chapter 19 - codeSpark Academy, Hopscotch, and Lightbot - Tablet-First Tools

Coding apps built for iPad and Android tablets come in many flavors.

- **codeSpark Academy plus The Foos** - US. Ages 5-9. Picture blocks with no text. Subscription around USD 10 per month.

Chapter 22 - AI Literacy - From MIT AI4K12 to National Standards

In 2024-2026, AI literacy for children moved from grassroots to government policy.

- **AI4K12** - MIT Media Lab and AAAI. Started in 2018 to define K-12 AI standards in five Big Ideas: perception, representation, learning, natural interaction, and societal impact.

- **Common Sense AI Literacy** - Common Sense Media (US nonprofit). Released in 2023, the guide targets teachers and parents.

- **Korea AI Education Standard** (2025) - Korea Ministry of Education official standard. Twelve-year K-12 alignment.

- **Japan MEXT AI Education Guideline** (March 2024) - Guidance for AI use and understanding across elementary, middle, and high school.

- **UNESCO AI Competency Framework** (2024) - Global standard.

The heart of AI literacy is not just using AI but understanding how it learns and decides. The hardest part is translating statistical foundations, bias, and hallucinations into language children can grasp.

Major kid-focused AI learning tools:

- **Teachable Machine** (Google) - Train image, audio, or pose classifiers in the browser with no code.

- **Machine Learning for Kids** - A free site by Dale Lane (UK) combining Scratch with IBM Watson.

- **Cognimates** - MIT Media Lab. ML plus robots.

- **PIC4Kids** - Korea. Image-recognition ML education.

- **Code.org AI Lab** - Code.org's integrated ML environment.

Chapter 23 - Risks and Safety - A Family Checklist

Kids coding tools come with real risks.

- **Roblox grooming** - The 2023 BBC Panorama documentary reported grooming of minors on Roblox. Roblox responded with under-13 chat restrictions and age-verified voice chat.

- **Minecraft server safety** - School-grade Minecraft Education is controlled, but Bedrock and Java public servers are not. Parental supervision is required.

- **Discord coding communities** - Many kids coding communities operate on Discord, but it is technically off-limits under 13, and Discord itself has safety concerns.

- **AI chatbot hallucinations** - Code.org Kira, Replit AI, and others can confidently produce wrong answers. Teach students not to treat AI output as the final answer.

- **Devex (Roblox) labor debate** - Creators 13 and up can earn money, but several reports flag patterns of children working unpaid or underpaid.

A parent and teacher checklist:

[Kids Coding Tool Safety Checklist]

1. Does signup require parental consent for under-13 users?

2. Are chat and messaging appropriately restricted?

3. Are ads displayed? If so, what kind?

4. Is personal data (name, school, location) collected? COPPA / Korean PIPA / GDPR-K compliant?

5. Is there a screen-time management tool?

6. Is there a parent dashboard?

7. Can the AI chatbot say "I am not sure"?

8. Can in-app purchases happen without parental approval?

Item 4 deserves attention. Korean law requires guardian consent for under-14 users, COPPA covers under-13 in the US, and GDPR-K applies to children under 13 to 16 depending on EU member state rules.

Chapter 24 - Teacher Resources - Free Curriculum

Tools alone are not enough; lesson plans matter.

- **Code.org K-12 Curriculum** - Free, K-12, standards-aligned.

- **Tynker Coding Teacher Curriculum** - Paid, with AI Lesson Plans auto-generation.

- **MakeCode Curriculum** - Official Microsoft material for micro:bit, Arcade, and Minecraft.

- **Scratch Teacher Resources** - Scratch Foundation official, including Scratch in Practice.

- **Raspberry Pi Foundation Teach Computing** - Free UK NCCE (National Centre for Computing Education) material.

- **CS50 for High School** (Harvard) - Professor David Malan's free high school course.

- **Hour of Code Activities** - Updated every December with 1,000+ one-hour activities.

- **Korea K-12 SW Education Resources** - Run by the Korea Education and Research Information Service (KERIS). Free.

- **Japan MEXT Programming Education Case Studies** - Free PDFs.

NCCE in the UK (operated by the Raspberry Pi Foundation) is especially strong. Funded by the UK government, it provides free certification courses (CS Accelerator) for Computing teachers.

Chapter 25 - National Policy - Why Coding Became Mandatory

The policy timelines for countries that mandated coding.

- **UK (2014)** - Computing curriculum, mandatory from age 5 to 14. Decided by Education Secretary Michael Gove.

- **Australia (2015)** - Digital Technologies, mandatory ages 5-15.

- **Korea (2018-2019)** - Software Education. Middle school 34 hours, elementary 5-6 17 hours mandatory.

- **Japan (2020-2022)** - Elementary 2020, middle 2021, high school 2022. The Common Test for University Admissions added the "Information" subject in 2025.

- **Estonia (2012)** - ProgeTiiger. Coding introduced from age five.

- **Singapore (2014)** - Code for Fun and Code@SG subsidies for academies.

- **United States** - No federal mandate. All 50 states include CS in standards, with around 20 making it mandatory.

Japan's shift is especially striking. The first appearance of the "Information" subject in the 2025 Common Test was historic, and the impact on motivation among high school students is significant.

Chapter 26 - Future Outlook - Kids Coding from 2026 to 2030

Closing thoughts on the post-2026 trajectory.

- **AI code assistants become universal** - Replit AI, Roblox AI Code Assist, Code.org Kira and others will appear in every coding environment. Teachers must redesign lessons so students think, not lean on the AI.

- **AR/VR coding** - Apple Vision Pro, Meta Quest, and Nintendo next-gen devices could host spatial coding tools. codeSpark already ships limited AR.

- **Robotics integration** - LEGO SPIKE Prime, micro:bit V2, Toio, and Sphero merge with on-screen tools. The line between digital and physical blurs.

- **Creator economy expansion** - The Roblox Devex model spreads to Minecraft Marketplace and Fortnite Creative, expanding income opportunities for teen creators.

- **Tightening ethics and safety regulation** - The EU AI Act (effective 2024, in force 2026) places dedicated requirements on kids AI. The US KOSA (Kids Online Safety Act) is close to passing, and Korea is reviewing tougher rules for under-14 users.

By 2030, a child building a first game in ScratchJr at five, collaborating on Roblox at ten, shipping an AI-powered app at thirteen, and contributing to GitHub open source at sixteen will be ordinary. The job of the 2026 tools and teachers is to lay the foundation for that trajectory.

The most universal starting point is Scratch 3.0: free, ad-free, Korean and Japanese language support, and a community of 100 million projects. The next step diverges to micro:bit plus MakeCode or to Roblox Studio.

For Korean schools, Entry is effectively the standard; in Japan it is Programming Zemi plus Scratch; in the UK and US it is Scratch plus micro:bit plus Code.org. Starting at home? Scratch on an iPad is the safest opening move.
