Free tools I built for my classroom.

When teaching in a school in the UK, I found most of the small tools I needed online wanted my email, or displayed a lot of ads (sometimes both!)

So, I started making my own resources. They're free and work in any browser.

If you have any suggestions for new tools, let me know at [email protected].

Tools

01

Exam Clock

Open

A fullscreen countdown for exam conditions. Logs extra time and rest breaks. Large, plain and readable from the back of the classroom. 

02

Tournament Manager

Open

Drop in a class list, run a league table and/or a knockout competition. Works for competitions or end-of-term quizzes.

03

Multiple Exam Clock

Open

A fullscreen board for exam halls running several papers at once. Each subject gets its own panel showing end times for normal and extra time groups.

04

Mark Scheme Calculator

Open

Enter raw marks and grade boundaries, get a full percentage table, box plot and grade distribution. Works for any exam board or in-house assessment.

05

Timetable Builder

Open

Build a colour-coded weekly timetable in minutes. Supports multiple weeks, day and week views, and exports to a print-ready layout.

06

Student Picker

Open

Paste a class list and pick a student at random. Fair mode works through everyone before repeating. Second tab splits the class into randomised groups.

07

08

Seating Plan Generator

Coming soon

Sketch a room, drop in names, get a printable plan. Editable in a couple of minutes rather than a free period.

Not available yet
09

Classroom Timer

Open

Countdown, stopwatch and live clock in one tool. Digital and analogue displays, fullscreen mode, lap tracking, and colour warnings when time is nearly up.

No account required.
Open a tool, use it, close the tab. There's nothing to sign up for.
No tracking or ads.
None of these tools track you or show ads. Most run entirely in your browser and store nothing online. The exception is the Tournament Manager, which saves names and scores to a database so the shareable link stays live. No account is needed and nothing beyond what you enter into that tournament is stored.
Works on the school laptop.
No installs. No school firewalls warnings. Plays nicely with whiteboards and projectors.
Requests welcome.
If there's a small tool you keep wishing existed, email me: [email protected]. I build what I can!
