Activities, worksheets and generators for children aged 3–14
Thousands of printable coloring pages, preschool worksheets, mazes and dot-to-dot sheets, plus generators that build a fresh A4 PDF in seconds.
Materials arranged by age and curriculum
Everything starts from one skill
The online activity, the worksheet generator and the printable PDF all point to the same curriculum skill. You pick the age, and the site walks you through the topics in curriculum order.
Practise online
Every topic has activities with instant feedback and a hint after a mistake. No timer.
Generator and PDF for the same skill
The printable and the generator use the same curriculum as the online activity. Nothing is bolted on.
Solver and error reports
A solver recalculates every answer, and two error reports put a task on hold until it is checked. Not all content is read by a person.
Worksheets, tracing lines and coloring pages as PDF
Print them and practise at the table. Every worksheet comes with an answer key where it makes sense.

How to Improve a Child’s Concentration While StudyingHow can you improve a child’s concentration? Start with short study blocks suited to their age, one task at a time, and movement breaks. A consistent workspace without a phone, enough sleep, and brief daily attention games such as mazes or picture sudoku can also help.

English for Kids: From Words to Sentences at Age 6For a 6-year-old learning English as an additional language, it is possible to move beyond single words without turning grammar into desk work. The easiest route is to reuse a few sentence patterns in play—“I like…”, “I can…”, “This is…” and “Where is…?”. Short role-play, songs and movement help children use them naturally.

Maths Puzzles for Kids: Build Logical ThinkingMaths puzzles build logical thinking when children have to spot a rule, eliminate possibilities, test an idea, and explain why it works. From Grade 1–8 / Year 2–9, useful formats include sudoku, sequences, balance puzzles, shapes, matchsticks, and logic problems. The key is choosing a level where your child can make the first move independently.

Labugen launches September 14, 2026: What's ready now and what's coming soon
Labugen is an educational portal featuring online activities, printable worksheets, and custom generators for kids from Pre-K to Grade 8. Our public launch is set for September 14, 2026. Here is a clear breakdown of what's currently available and what we're building next.
Read more
We are creating a single platform where interactive screen activities, worksheet generators, and printable pages all focus on the same core curriculum skill. Parents simply select their child's age, and the portal guides them step-by-step through curriculum-aligned topics in math and language arts, for ages 4–6 through Grade 8.
What's available today
- 12 age levels, 53 units, and 73 topics organized by standard learning goals.
- 168 ready-to-use activities in six formats: multiple choice, fill-in-the-blank, matching, ordering, true/false, and visual counting.
- 54 printable materials: tracing patterns, worksheets, mazes, and connect-the-dots.
- 6 worksheet generators that create a brand-new printable page every single time.
- 8827 coloring pages across 111 categories.
- 4 learning games, including "Keyboarding Master" with language-specific keyboard layouts.
- 3 parent guides.
Everything listed above is available completely free, no account required.
What we're working on until September 14
We are fine-tuning what's currently visible: unit descriptions, topic additions for older grades, and new articles for our parent guide. The next major step is the learning hub—featuring parent accounts, child profiles, review schedules, and progress reports. Today, the learning hub and payments are DISABLED and cannot be used; once active, we will announce it here and in our newsletter. Early supporter pricing for full access will be 199 zł per year, while public pages, generators, and account-free activities will remain free forever.
Who runs Labugen
The portal is run by an independent solo founder. Content is created with AI assistance: math problems are recalculated by a solver upon every save, but not all content is read by a person, which is why every activity has a “Report a problem” button. If you teach early childhood or elementary education and would like to help review materials, please drop us a line.

Labugen is currently in beta: Found an error? Let us know
Labugen is currently operating in beta mode and evolving daily. Errors can happen—and we want to know about them, because just two user reports will automatically pause an activity for review.

What "beta" means here
- We are constantly adding new content, so lists and totals update from day to day.
- Page layouts and web addresses may still change.
- Certain features—such as parent accounts, the learning hub, and payments—are currently turned off and will launch in the next phase.
Our learning activities are built using AI models, and each carries a designated risk level. Numerical exercises are verified by an automated solver that recalculates results on every save, preventing flawed templates from being published. Language rules, reading passages, and parent guides are also created with AI, and not all of them have been read by a person. Illustrations are checked with automated quality measures, and some of them have been assessed by a model that compares the drawing with its description. Despite our efforts, a typo in an instruction, a mismatched graphic, or a worksheet generation error may occasionally slip through.
How to report a bug
Every activity features a "Report an Issue" button, and we also have a dedicated page at /zglos-blad. Simply let us know what's wrong—the task ID and URL are added automatically. Your submission enters our moderation queue, and any item receiving two reports is automatically paused until reviewed. Providing your email address is optional; include it if you'd like a response.
Non-bug inquiries
For general questions, partnership ideas, data privacy concerns, or legal notices, use the contact form at /kontakt or email contact@labugen.com. This single inbox serves all regions; feel free to write in your language, and we will reply in the same.

Labugen mobile app: Planned release on October 1, 2026
We are developing our mobile and tablet app, with a planned launch date of October 1, 2026. Join the waitlist with your email, and we'll notify you on launch day.
Read more
The app will offer everything available on the website, optimized for touchscreens: the same interactive activities with instant feedback, the same printables and coloring pages, and the same age-based, curriculum-aligned structure. No countdown timers, auto-play features, or artificial rewards just for logging in—learning sessions have a clear finish line so kids know when to stop and step away.
Why launch after the website?
Because the app shares the exact same content database and quality control pipeline, our web platform needs to be fully in place first. That dictates our roadmap: the website launch on September 14, followed by the learning hub, and then the app release on October 1.
Please treat this target date as our internal goal rather than a guaranteed app store promise. If timelines adjust, we will post an update here under News and notify everyone on the waitlist. We would far rather delay a launch than release an app with inaccurate learning math.
How the waitlist works
Signing up requires just one email address and one consent checkbox. We send a confirmation email with a link—nothing is saved until you click to confirm—followed by a single notification on launch day. Unsubscribing takes a single click from that same email, and leaving the waitlist will not affect your main newsletter subscription or vice versa. We never share your email address with third parties.
App waiting list
Leave your email address and we will write on the day the app launches. One message, no ads.
