A classroom-friendly playground

Learning
with Prime.

Maths puzzles, coding thinking, and creative tech — all in one page. No logins. No data collection. Just practice.

Tip: This page runs entirely in your browser. It’s fine for school testing and demos.

Precision, curiosity, and calm practice.

This is a non-commercial learning page inspired by the “Douglas Prime” idea: building strong thinking through maths, coding, and creative tech.

  • ● No sign-up, no “contact us”, no tracking — suitable for classroom use.
  • ● Hints are optional — students can try first, then reveal steps.
  • ● Random problems — one “problem type” becomes many versions.

Learning Lab

Try the problem. If you get stuck, reveal hints one step at a time.

Maths

Simultaneous Equations (Elimination)

Generate a new version of the same skill. Answers stay integers.

Question

(Type your answer below. Use integers.)

Hints

Coding thinking

Quick Coding Prompt

Write pseudocode (or real code) for this:

Prompt

Given integers a, b, c, generate an equation ax + by = c that has an integer solution. How would you guarantee it?

Optional extension: what checks would you run to avoid “too easy” cases?

Privacy

Nothing is sent anywhere. If you type notes in the Teacher section, it can be saved locally on this device only.

Mini Projects (Optional)

Short ideas that connect maths, coding, robotics/electronics, and sound design — in a school-safe way.

Time & Patterns

Record a repeating pattern (claps, steps, drum hits). Model it as a sequence. Predict the 50th term. Then test it.

Robotics Route

Plan a “robot” route on squared paper: instructions like forward 3, turn right, forward 2. Translate between words, coordinates, and code.

Sound & Ratios

Explore pitch as a ratio. What happens when you double frequency? Connect it to octaves and patterns.

Teacher Notes

Optional notes area for lesson use. Save locally (on this device) or copy to clipboard.

Safeguarding / data

  • • No accounts, no emails, no submissions.
  • • If you use “Save”, it stores text only in your browser’s localStorage.
  • • For shared school devices, avoid saving and just use “Copy”.
