I have built a number of online tools over the years to support teachers in both maths and general school areas.

I am not a particularly good programmer and my code has always been about being functional rather than well written. Recently I have taken advantage of the Generative AI coding tools that have become available, to build things that I wouldn’t have had the time or skill to do on my own. I try to stick to languages that I have some understanding of (html, css, PHP, JS), but mostly rely on ‘vibe coding’, although I do take time to architect the projects and ensure some care over security etc when needed. These are not one shot apps from AI and some have taken several months to build.

Here are the app projects that are up and running in some form. I will write more detail about them soon.

General Education apps and Maths apps

General Education

TeachTeach Tools

teachteach.tools/ A collection of small utilities for teachers. Mostly built because I needed something.


curriculumtracker.app

This is the biggest app I have built. It’s a fairly complex platform for teachers to track what has been taught to their classes.


vocabapp.uk

Designed to help pupils learn vocabulary, the Learn Vocabulary app is uses a spaced repetition algorithm and supports multiple quiz and learning modes.



Maths apps & Websites

mathsduck.co.uk/

My original maths website that now links to my other maths tools.


mathsduck.co.uk/ukmt/

This is one of my hand coded apps from several years ago. It organises and displays past questions from the UKMT maths challenges.


Formulae for GCSE

mathsduck.co.uk/formulae/

A simple app to help pupils learn the formulae they need for GCSE maths.


BoostMaths.uk

A focused tool to help pupils practice the basic skills and facts that they need to achieve at least grade 4 at GCSE. Intentionally not comprehensive curriculum coverage. More of a scalpel than a swiss army knife.


MathsIndex.uk

Curated tools and resources for secondary maths teachers that help build conceptual understanding. My attempt at gathering things from around the internet and cataloguing them so that they can be found easily.


SenseMake.uk

My small collection of interactive maths tools for the classroom. Designed to help build pupils’ understanding of mathematical concepts.


NumberLine

numline.com/

A number line app where the line can be scrolled perpetually in both positive and negative directions. Single and double number lines and various tools to support using it for teaching. This is in beta and is not fully finished. There are bugs and missing features.
