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

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.

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

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

I’m unfamiliar with that thought but can see how useful it is particularly with secants. Thanks.

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
