Lua for Kids: Learn Lua and Luau with Real Code

Quick answer

Lua is a small, free programming language made at a university in Brazil, and Luau, the language of Roblox Studio, is built from Lua 5.1. Children aged about 8 to 14 can learn it live online with Modern Age Coders, in a batch or one to one, through our Roblox Game Coding course, whose second month teaches Luau from zero inside Roblox Studio.

What Lua is

Lua in eight facts, from the people who make it

Rather than repeat other summaries, here is what lua.org, the official site, says about the language, so a parent knows what their child is actually learning.

Lua facts from lua.org (read 17 October 2026)
Question	What lua.org says
What is it?	"a powerful, efficient, lightweight, embeddable scripting language"
Who makes it?	A team at PUC-Rio, the Pontifical Catholic University of Rio de Janeiro in Brazil
What does the name mean?	Moon, in Portuguese. It is pronounced LOO-ah, and lua.org asks people to write Lua, not LUA
How old is it?	Versions have been released and used in real applications since its creation in 1993
Latest version	Lua 5.5, released on 22 Dec 2025; the current release is Lua 5.5.1, released on 03 Aug 2026
How big is it?	The Lua 5.5.1 package takes 390K compressed, and the source is around 32000 lines of C
Where is it used?	lua.org names games such as World of Warcraft and Angry Birds, and calls Lua the leading scripting language in games
What does it cost?	Nothing: free open-source software under the MIT license, usable for any purpose

Why small matters for a child

A language small enough to describe in one reference manual is a language a ten-year-old can hold in their head. Lua has a short list of keywords and one main way to build collections of data, the table. Children reach the point of writing their own games much sooner than in larger languages.

The manual describes Lua as dynamically typed, which it explains as "variables do not have types; only values do." In practice a child can write score = 10 without first announcing that score is a number.

Two rules that trip up beginners

Lua is case-sensitive. The manual’s own example is that and is a reserved word, but And and AND are two different, valid names. So a capital letter in the wrong place is enough to stop a program, and spelling is the first thing to check.

Only two values count as false: the manual says both nil and false make a condition false, and any other value makes it true. That includes zero, which surprises children who have met other languages first.

Sources, read 17 October 2026: About Lua, Lua version history and the Lua 5.5 Reference Manual. We are not connected with Lua.org or PUC-Rio.

Type it, run it

Three Lua programs a child can run today

Three short programs we wrote for a first Lua session. We used only functions described in the Lua reference manual: print, ipairs, string.format and math.random. They run in any recent version of Lua, including the browser sites listed on lua.org.

Program 1 · variables and decisionslua

-- Program 1: a greeting robot (ours)
local name = "Maya"
local age = 10

print("Hello, " .. name .. "!")

if age >= 13 then
  print("The teen group is for you.")
elseif age >= 8 then
  print("Time for your first game script.")
else
  print("Scratch first, then Lua.")
end

With age set to 10 it prints two lines: Hello, Maya! and then Time for your first game script. Change the number and run it again to see the other branches.

Program 2 · a table and a looplua

-- Program 2: coins collected on five levels (ours)
local coins = {12, 0, 7, 25, 3}
local total = 0

for level, amount in ipairs(coins) do
  if amount ~= 0 then
    total = total + amount
  end
  print("Level " .. level .. ": " .. amount)
end

print(string.format("Total coins: %d", total))

The manual says ipairs walks a table from position 1 upward, up to the first absent index. Our arithmetic for the final line: 12 + 7 + 25 + 3 = 47, so it prints Total coins: 47. The two dots join pieces of text together, and the tilde-equals sign means not equal.

Program 3 · a function and randomnesslua

-- Program 3: a dice duel against the computer (ours)
local function roll()
  return math.random(1, 6)
end

local you = roll()
local robot = roll()
print("You rolled " .. you .. ", the robot rolled " .. robot)

if you > robot then
  print("You win!")
elseif you < robot then
  print("The robot wins this time.")
else
  print("A draw. Roll again!")
end

The manual says Lua seeds its random generator so that results differ each time the program runs. Our probability note: two dice make 36 equally likely pairs and 6 of them are draws, so a draw comes up about once in six games (6 / 36 = 1/6).

A practice set to try after the three programs (ours)
Task	Hint	You know it works when
Greet three different names	Copy the print line and change the name	Three greetings appear, each on its own line
Add a sixth level to Program 2	Put another number at the end of the table	The total grows by exactly that number
Count the empty levels	Make a second variable that adds 1 when amount is 0	With the table above it prints 1
Make the dice fairer to you	Roll two dice for yourself and keep the higher	You win clearly more often over twenty games
Play three rounds	Wrap the duel in a loop that runs three times	A final line announces who won more rounds

Lua and Roblox

Lua and Luau: what stays the same, what Roblox added

Roblox does not run plain Lua. It runs Luau, and Roblox’s documentation describes Luau as a fast, small, safe, gradually typed embeddable scripting language derived from Lua 5.1. The Luau project’s own history says that around 2006, Roblox started using Lua 5.1 as a scripting language for games, and later reshaped it.

Lua 5.5 and Luau side by side, from lua.org and luau.org (read 17 October 2026)
Feature	Lua 5.5	Luau
Starting point	The current official Lua	Built on the Lua 5.1 syntax, with additions
Comments, tables, if and for	The core of the language	The same, so Lua lessons carry straight over
Adding to a variable	Written out: `total = total + amount`	Also allows compound assignment: `+=`, `-=`, `*=` and others
Skipping a loop step	No continue statement in the manual	Has continue, which must be the last statement in the block
Putting values into text	Joining with two dots, or string.format	Backtick strings with braces, such as Total: {total}
Types	Values carry types; variables do not	Optional type annotations, checked by a gradual type system
Numbers	Integers and floats since Lua 5.3	A single number type, a 64-bit IEEE754 double
New in the latest release	Declarations for global variables, among other changes	Separate releases on luau.org

Program 2 in Luau · for Roblox Studioluau

-- Program 2 again, rewritten in Luau (ours)
local coins: {number} = {12, 0, 7, 25, 3}
local total = 0

for _, amount in coins do  -- Luau loops over a table directly
  if amount == 0 then
    continue                -- skip empty levels
  end
  total += amount
end

print(`Total: {total}`)

Same coins, same answer: it prints Total: 47. Every new piece here, the type annotation, looping over a table without ipairs, continue, += and the backtick string, is documented on luau.org. It will not run in plain Lua, which is exactly the lesson.

Learn Lua first, or go straight to Luau?

Our Roblox course works inside Roblox Studio from the first week, because that is where the excitement is, and its second month teaches Luau from zero: variables, values, then loops and functions. Those four ideas are identical in both, and a child who owns them reads any Roblox script with confidence.

The extras Luau adds are conveniences. A good way to meet them is one at a time, with the long Lua way shown first, as in the two versions of Program 2 above.

What Roblox adds on top of the language

Separate from Luau itself, Roblox gives scripts a huge library of game objects: players, parts, sounds, events. That library is Roblox-only. Lua and Luau are the grammar; the Roblox engine is the world the grammar talks about.

Our guide to making a Roblox game shows three Roblox scripts that use that library, including a leaderboard and a coin that counts.

Sources, read 17 October 2026: Why Luau?, Luau syntax by example, the Roblox Creator documentation page on Luau, and lua.org. Roblox Corporation has no connection with Modern Age Coders.

Where to write it

Where a child can write and run Lua, including on a Chromebook

This is the practical question in many American homes, where the school laptop is a Chromebook. The answer depends on whether your child is writing plain Lua, plain Luau, or a Roblox game.

Where each kind of Lua code runs (from lua.org, luau.org and the Roblox Creator docs, read 17 October 2026)
What your child is writing	Where it runs	Works on a Chromebook?
Plain Lua, like Programs 1 to 3	Lua installed on a computer, or a browser site from the list on lua.org’s demo page	Yes, through a browser site
Plain Luau, like the rewrite above	The Try Luau online playground on luau.org	Yes, in the browser
A Roblox game	Roblox Studio on Windows or Mac	No: Roblox says Studio cannot run on Chromebooks

A note for parents on browser sites

The sites on lua.org’s demo page are run by other companies, not by the Lua team. Check each site’s terms and sign-up rules with your child before using one, and prefer sites that run code without an account.

The Luau playground is run by the Luau project itself, which makes it the simplest place to try the Luau version of Program 2 above.

If Roblox Studio is the goal

Roblox Studio needs a Windows or Mac computer, and Roblox’s education team suggests Studio for children of about 10 and older. Children younger than that, or without such a computer yet, lose nothing by starting with plain Lua in a browser.

When the computer arrives, the move is short: the same loops and tables, now moving parts and counting coins.

A first course

Ten classes from first print to first Roblox script

A path we suggest for a child starting Lua one to one, ages about 9 to 13. Younger children take it more slowly and older ones skip ahead.

A ten-class Lua and Luau plan (ours)
Class	What the child writes	The idea underneath
1	Program 1, then a robot that greets the family	Variables and text
2	Choose-your-path stories with if and elseif	Decisions
3	Program 2 and the practice set	Tables and loops
4	A times-table quiz that keeps score	Loops with a counter
5	Program 3, then a rock-paper-scissors game	Functions and randomness
6	The Luau rewrite and the four Luau extras	One idea, two dialects
7	First Roblox Studio script: a part that changes color	Objects and properties
8	A coin that counts points	Events
9	A small obstacle course with checkpoints	Putting it together
10	Explaining every line of their own game to the class	Reading code aloud

Ages 8 and 9

Shorter programs, lots of changing numbers to see what happens. Some start in Scratch, which shares the same ideas.

Ages 10 to 12

The full ten classes, then on to the rest of our Roblox course.

Ages 13 and 14

Faster through the core, then Luau types and modules, and a step towards Python or C#.

After Lua

What Lua prepares a child for

When Lua is the first language a child types rather than drags, what comes next matters as much as the first program.

Next steps after a first Lua course (ours)
If your child enjoyed	Try next	Why it follows
Scripting games in Roblox	More Luau, in our Roblox course	Bigger games, the same language
Writing the programs themselves	Python	Tables become lists and dictionaries; loops and functions look familiar
Making games outside Roblox	Godot or Unity, later	Full game engines for teenagers
Puzzles and logic	Coding challenges	The same loops and conditions, under a clock

Signs of progress

How a child’s Lua grows

Four steps we watch for, from copying to inventing.

Stages in learning Lua (ours)
Stage	You will notice
1. Copier	Types programs exactly and fixes typos when they break
2. Changer	Edits numbers and words to make the program do something new
3. Combiner	Puts a loop inside an if, or a function inside a loop, without being told
4. Inventor	Starts a blank file with a plan of their own

For parents

The jump from copier to changer can come quickly. Ask your child to show you what one number in their program does.

Combiner is the big one. It is where a teacher earns their keep, by setting puzzles that need two ideas at once.

For kids

When something breaks, read the error message slowly, from start to end, before changing anything.

Say what each line does out loud. If you cannot, that is the line to ask about.

Parents ask

Lua for kids: questions parents ask

Is Lua a good language for kids?

For a child who reads and types comfortably, yes. Lua is small, free and readable, and lua.org describes it as lightweight. It is also the base of Luau, the Roblox language, so a child who wants to make Roblox games has a strong reason to learn it.

What is the difference between Lua and Luau?

Luau is the language of Roblox Studio. Roblox describes it as derived from Lua 5.1. It keeps the Lua core and adds extras such as +=, continue, backtick string interpolation and optional type annotations.

What age can a child start learning Lua?

Around 9 or 10 is a sensible start, once a child reads and types comfortably. Roblox says its education team typically recommends Roblox Studio for ages 10 and up. Younger children often begin in Scratch, which teaches the same ideas in blocks.

Is Lua free?

Yes. lua.org says Lua is free open-source software under the MIT license and may be used for any purpose at no cost. Roblox Studio, where Luau runs, is also free to install on Windows or Mac.

Can my child learn Lua on a Chromebook?

Plain Lua and plain Luau, yes, in a browser: lua.org lists sites that run Lua online and luau.org has its own playground. Roblox games are different, because Roblox says Studio cannot run on Chromebooks.

Is Lua hard to learn?

It is one of the gentler typed languages. The main surprises for children are that capital letters matter and that only nil and false count as false. The three programs on this page are each about a dozen lines.

Does my child need Roblox to learn Lua?

No. Plain Lua runs anywhere Lua is installed or in a browser. Roblox becomes useful when your child wants to turn Lua skills into games friends can play.

Which version of Lua is the latest?

lua.org says Lua 5.5 was released on 22 December 2025, and the current release is Lua 5.5.1, released on 3 August 2026. Roblox uses Luau, which follows its own releases.

What can kids make with Lua?

Text games, quizzes and dice games in plain Lua; in Roblox Studio, full games with coins, leaderboards and obstacle courses. lua.org also lists professional games that use Lua, such as World of Warcraft and Angry Birds.

When are the Lua classes held?

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.

How much do Lua classes cost?

The first class is free. After it, teaching is paid monthly, and the exact US dollar figure sits in the Fees section of this page.
