A classic logic puzzle has been given a Transum home: buff.ly/abnFh58 I've called it "Only One Each". Place the tents so that each tree has one tent next to it and no two tents are next to each other. #mathsresources #mathschat #mathstoday #puzzle #tents

The Sieve of Eratosthenes: still in its prime after more than 2,000 years! buff.ly/YkMWphG I've updated the interactive version on Transum. Students colour in multiples to reveal the prime numbers up to 100. A colourful lesson in elimination! #mathschat #maths #mathstoday #mathsresources

I recommend bookmarking the Refreshing Revision page for quick access. It is designed to be projected as a starter or lesson ending. Scroll down the page to see how you can customise the questions to suit your class. There's a pro version for subscribers too. buff.ly/fbeZGqI #mathstoday #Maths

What a pity that International Talk Like a Pirate Day falls on a Saturday (today, the 19th of September), when most classrooms are empty. The maths lesson starter for today is one in which pupils have to say numbers in a pirate voice and the numbers keep doubling.

Exercises on the Transum website, such as Quadratic Gaps, are tools for teachers to use as and when appropriate, alongside other resources and approaches. Mix and match to suit your pupils. Variety is valuable, and each activity is just part of the bigger picture. www.transum.org/Intro/?ID=1193

A gentle introduction to parallel and perpendicular lines for younger learners. This new exercise has four self-marking levels to help pupils get a feel for the terms before using them in geometry or graphs. No preparation needed, just send the link. www.transum.org/Intro/?ID=229 #mathstoday

Like many well-known films, Transum’s angle exercises now have a prequel! It’s called Angle Names, and all you have to do is identify each angle as acute, obtuse, reflex and so on. www.transum.org/Intro/?ID=1192 #mathsresources #mathschat #mathstoday #mathchat #lessonstarter

Do you miss those days when you could type a number on your calculator, turn it upside down, and then be amused by the word it produces? They don't make calculators like they used to but there is an exercise here with a rotating calculator! www.transum.org/Intro/?ID=217 #mathstoday #mathschat

I had the thought that when a student completes a multiple-choice survey, data is collected, but their thinking may also be influenced as they read through the possible answers. So here is a little experiment: teaching through a survey about calculator use! www.transum.org/Maths/Activi...

Mixed media learning (sounds good). Students complete construction exercises using a pencil, ruler and compasses, then measure a length on their construction. They type it online, which awards the mark if within a given tolerance. www.transum.org/Intro/?ID=403 #mathsresources #mathstoday

I really do believe that the final Maths lesson of the academic year should be something special: a puzzle, quiz, game or craft activity all with a mathematical essence. I’ve collected lots of great ideas over the years and brought them together here: www.transum.org/Software/Fun... #MathsToday

transum.bsky.social @transum.bsky.social · 15/06/2026

GCSE Maths questions on comparing data often ask pupils to write comparisons in sentences. That’s tricky for self-marking, so I thought to do it differently: decide whether each statement is True, False or Cannot be determined. www.transum.org/Intro/?ID=1179 #mathsresources #mathstoday

transum.bsky.social @transum.bsky.social · 11/06/2026

I can’t remember the last time the intersecting chords theorem appeared in a syllabus I was teaching, but it is still very much around. So, of course, it deserves its own Transum exercise. www.transum.org/Intro/?ID=1178 #mathsresources #mathschat #mathstoday #mathchat
