5 Random Tools for Teachers (Built by Developers)

As developers, we often build tools for ourselves. But when we build with educators in mind, the impact can scale quickly.

Teachers juggle dozens of tasks—often without the right digital support. That’s where simple random generators shine: fast, free, and flexible for dozens of use cases.

Here are 5 random generators (including one we made) that educators will love.

🔡 1. Random Letter Generator

We built this tool to be dead simple. Just click and get random letters. Ideal for ESL teachers, creative writing prompts, phonics games, or just breaking the ice.
• Choose how many letters you want
• Allow or disallow duplicates
• Works on all devices
• Lightweight and fast

💡 Open source on GitHub: github.com/o140445/random-letter-generator

🧮 2. Random Number Generator (by CalculatorSoup)

Generate custom number ranges for classroom games, pick-a-student moments, or math drills. Fully customizable, no login required.

📚 3. Writing Prompt Generator

Use it to spark creative writing or journal entries. Many teachers use this in “quick write” sessions — the tool generates characters, plots, or first lines.

📦 4. Random Word Generator

A classic. Set part of speech, quantity, or language level. Good for vocabulary warmups or timed writing games.

🎵 5. Random Music Generator

Music teachers, rejoice: this tool gives random notes, chords, and intervals for sight-reading, ear training, and practice drills.
