Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 9 April 'Starter of the Day' page by Jan, South Canterbury:

"Thank you for sharing such a great resource. I was about to try and get together a bank of starters but time is always required elsewhere, so thank you."

Comment recorded on the 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary:

"I use Starter of the Day as a registration and warm-up activity for my Year 6 class. The range of questioning provided is excellent as are some of the images.
I rate this site as a 5!"

Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.

The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing.

Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.

#### Equatero

Find the mathematical expression from a series of guesses and clues. This is the numerical version of the extremely popular internet sensation Wordle and UK TV quiz show called Lingo.

There are answers to this exercise but they are available in this space to teachers, tutors and parents who have logged in to their Transum subscription on this computer.

A Transum subscription unlocks the answers to the online exercises, quizzes and puzzles. It also provides the teacher with access to quality external links on each of the Transum Topic pages and the facility to add to the collection themselves.

Subscribers can manage class lists, lesson plans and assessment data in the Class Admin application and have access to reports of the Transum Trophies earned by class members.

## Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

"ONE THOUSAND KILOS? Is an anagram of OH, SOUNDS LIKE A TON!

This seems ideal for kicking off a discussion about the difference between a metric tonne and the more confusing ton options (where a long ton is 2240lbs and a short ton is 2000lbs)."

## Imperial Units

Just when I thought I knew all of the imperial units I heard Matt Parker (Standup Maths) list them all, even the more obscure ones, in this wonderful monologue. When you hear their names and their relative sizes you cannot help but be grateful for the metric system which is more common today.

More or Less Podcast Matt Parker's Website Transum Podcast

This audio excerpt is from an excellent podcast from BBC Radio 4 called More or Less: Behind the Stats in which Tim Harford tries to make sense of the statistics which surround us. It's well worth a listen if you have an interest in mathematics and statistics and provides real world examples of the maths we learn in school.
