Ask HN: How are you teach your kids programming in 2025?

[chenxi9649]

Hi HN, my nephew is 11, and I'm planning on giving him my old laptop.

However, I don't want him to JUST play games 24/7 but for him to do something productive like learning how to code. And I'll meet with him once per week to check up onhim.

My dilemma is that AI has completely changed how I personally code(and learn things), and all of the existing courses/curriculums for kids just feel a bit archaic...

Obviously, I can't just tell my nephew to go talk to chatgpt all day long and learn, without a project plan/target, he's gonna drift off(as I would too). I'm also thinking, since my main goal here is for him to just learn, maybe we should even just start with basic math/science instead of straight into coding?

I don't have any kids myself, so I'm curious to learn how all of the parents on HN are educating their kids today! Anything is helpful :)

I run Hack Club (https://hackclub.com), a nonprofit where lots of high schoolers learn to code and build awesome projects together.

Here is how the ones who are successful do it:

1. They make small technical projects they're proud of, like this https://gabitzu3.github.io/MemeOS-v0.1/

2. They do it in a way where they make friends (ex. on the Hack Club Slack, on Discords, or by going to in-person events like https://daydream.hackclub.com which is an upcoming global game jam we're hosting)

3. They do it in a way where they go on memorable adventures (either physical - like traveling to hackathons, or intellectual - like trying to build a compiler from scratch)

I don't have direct experience yet since my son is only 0 years old, but I'm absolutely planning to introduce him to competitive programming when he's older.

I personally got hooked on AtCoder and Codeforces when I was in middle school. Back then, many contests started around 2 AM Japan time, which was tough, but it was incredibly fun. That experience is what led me to become a software engineer.

This hasn't changed even in the AI era. I now have Claude Code write most of my code, and I don't spend nearly as much time actually writing code as I used to. However, the underlying data structures and algorithms still excite me immensely. There's something deeply satisfying about understanding the fundamental concepts and problem-solving techniques that no AI tool can replace.

Competitive programming teaches you to think algorithmically and break down complex problems - skills that remain valuable whether you're writing code yourself or directing AI to do it for you.

atcoder in middle school? and having kids now? wow

I guess yeah, we are getting old...

My son is 12, and we've just started in on learning coding. To make it fun, we're making a game together. He does all the art and game design, and I do all the coding. To help him learn coding, I make him sit with me while I do the easy parts, so that he learns concepts. I explain things like variables, loops, and functions, and then talk through the design with him. He 'helps' me solve things at a high level, and then I show him what the solution looks like. At his age I think simple exposure to concepts is important, as it will make things easier if he gets into it himself when he's older. As for AI, it is still just a tool to make devs more productive, you still need to understand coding to get the most out of it. With that in mind, the basics are just as important as ever.

I started my kids at a young age on a physical mouse robot they had to instruct to navigate a maze. Scratch JR was the next step. I always found a way to keep it fun. Around age 8 I gave my daughter basic lessons in Scratch. Adding in the MakeyMakey was a lot of fun as it adds a physical component.

In sixth grade I introduced microbit to her class with the MS MakeCode block coding. I had them build their own robots from a pile of legos and mini servo motors. Each lesson taught them one small part they could use towards their final challenge to build a car they could navigate a maze with in the shortest time. They were paired up in teams of two. They learned a lot about real world engineering.

I am playing around with the idea of some LLM projects but so far I have focused on a fun project based approach.

First thing I'd say is to figure out if the kid has real interest and willingness to learn programming/computers at all. If you want to find motivation, figure out what topic/hobby the kid is interested in, and code together something useful/fun/inspiring in that domain. After all, all real world programs are used for some specific domain.

Second thing is the young age of 11 (of course depends on invividual). "Real" programming requires understanding very abstract concepts (like memory, objects, functions, variables, loops, program state/execution model etc.). I remember when I was young (maybe ~13 yo), and I struggled alone with C++ and Delphi. I could copy and paste some code, but I couldn't really understand what make them work (or didn't). Of course it was different time then (no youtube tutorials, no AI, no good quality open source stuff etc.).

Third thing, if the kid is interested to learn, is good environment/language to start with. I'd start with plain vanilla HTML5 (HTML + CSS + JS). It's relatively easy to get feedback and interactivity with it, and it runs on every computer and mobile device. And the whole program - content (HTML), layout (CSS) and interactivity (JS) - can be in a single file and "recompiled" just by clicking refresh button. I wouldn't use any JS frameworks, because then it becomes learning something else than real basics. With couple of lines JS, you can draw graphics, play sounds based on keyboard/mouse/touch interactivity etc. But of course, even if its just handful of HTML5 APIs, to teach someone why/how they work is a big task.

Fourth thing, now with AI, for many, learning seems to have become a process of collecting random factoids here and there, and then trying to make some sense of the whole mess. I'd say a great book that presents an overview of a topic from start to end is overly underrated at this point of time. When book(s) stops giving lessons, use LLM(s)/professional(s). When LLM(s)/professional(s) stops giving you lessons, you are at the frontier of knowledge, and you have to figure it out yourself by teaching yourself :)

This is not a junior dev you can have a weekly one-on-one with, budget a whole lot of time and find a dirt-simple tutorial to go through.

I'm partial to PhaserJS because it's browser-based, not too much required to get started, lots of simple game tutorials and lots of instant-feedback making characters move and stuff.

Be prepared to cover a lot of basic computer usage and math.

[gus_massa]

I'd start with Python and drawing with the turtle package.

On the other hand, I remember a few nice posts about Scratch, but my daughter preferred to use a text based language.

Coding is meant to solve problems. And AI doesn’t know Jack about humans, only the breadcrumbs they leave on the internet. (Opinion)

One idea is to pose problems at a high level and ask how one would solve them.

A reference is Strategies forCreative Problem Solving, by Fogler and LeBlanc

I recall an early day at work when I called the boss that I would be in late, running some numbers on the home computer (in Basic). They were tradeoffs using various ranges of variables. The alternative was the IBM 360, fat chance. He looked a bit angry when I sauntered in, but when I showed him the printout, he realized that I had done about a week’s worth of work. Basic is out the window now, but the point is to go from a problem to proposed solutions (TMTOWTDI) [0] and there may be more than one way. In fact, that might lead to a globally better solution than some local peak and certainly more instructive, as in proofs of Pythagoras’ Theorem.

Through successive narrowing down, one finally gets to what AI does “best”, boilerplate, and by isolating its output, one can actually test the result with a smaller range of inputs.

Okay, I am not, nor was I a professional coder. More a scripter and admin, tasked with solving problems in the quickest way. Perl did most of the heavy lifting. So, I am not griping on pro’s.

The main thing I liked about perl, and groovy and python, which I didn’t need to use, was the existence of tested libraries. So, with groovy, I could access all the java libraries. No doubt the same for others. I have no idea how to impress this on others, since I think it’s way more trustworthy than black-box code, but I do recommend it. To what extent AI is going to reinvent the wheel on every coding request from it’s giant parts bin, I don’t know.

I believe that the value is in translating problems and needs into potential solutions and finding or choosing a “best” one. Code blocks are a dime a dozen, or perhaps better put, 45+ cents a kilowatt. (In CA). It’s how you string them together that makes all the difference. A wheel for climbing stairs may be three-lobed or even legged [1].

A beginner is going to get no insight from black box output, IMO. More from documented examples and libraries. I learned a ton about perl from the rdb relational database by Hobbs, [2], reading through it and learning what was going on and how. It was open source, and has moved to github.

Of course, you might suggest something newer than all of the above, but start simple, of course.

I liked things like map() and such, as an alternative to looping, but that may be on the advanced side.
