Transum Mathematics

Transum Mathematics is a long-running library of lesson starters, puzzles, games, investigations, topic practice, and classroom tools. Teachers can grab a five-minute opener; learners can wander from times tables to logic, vectors, or exam questions. The catalog is generous and gloriously sprawling, so a topic in mind helps.

What is Transum Mathematics?

The obvious front door is Starter of the Day, a calendar of quick problems built for the opening minutes of a lesson. Keep walking and Transum turns into a whole mathematics workshop: number games, interactive puzzles, investigations, revision routes, times-table practice, exam questions, classroom-display ideas, and teacher utilities. Topic pages range from arithmetic and fractions through algebra, statistics, vectors, and calculus. Some games support two players or teams, while other activities are solo challenges. The site has been growing since 1997 under retired mathematics teacher John Tranter, and its homemade breadth is the point: this is less a sleek course than an enormous cabinet of useful provocations.

What you can do there

• Choose a daily lesson starter
• Solve mathematics puzzles and exercises
• Play topic-based mathematics games
• Browse resources by topic or audience

Why we picked it

Transum is unusually good at supplying a concrete thing to do right now. A teacher can find a warm-up before the register is finished, while an independent learner can trade routine drills for number puzzles, strategy games, and open-ended investigations. Independent educator material also confirms that the starters and games have found real classroom use.

How to get the most from it

If you are teaching, begin with Starter of the Day, then use the Topics index when the random choice misses your lesson. Learners should try Maths Map for a structured route or head straight to Games and Puzzles for a looser challenge. Set a topic and difficulty goal before browsing; otherwise the sheer number of mathematical rabbit holes can consume the period.

Good to know

Most resources are free, while optional subscriptions help support the site and some pages carry advertising. Sign-in, subscription, Class Admin, and student-tracking tools sit alongside material that can be opened directly. The site's privacy guidance asks schools to use only first names or nicknames in class tools. Expect a dense, long-grown catalog rather than one uniform interface.

Who made it, and when?

John Tranter is the credited creator or organization. The earliest supported launch date we found is 1997. A documented update was recorded August 2026.
