•
• Great - a little too easy, but interesting for all!
Need some more like this!
• D.Wanasingha, PGCE (UOH)
•
• The answer 14 is if we arrange them as a line. Otherwise it reduces to 10 when we consider it as a circle. If it is a line it would be a quite tricky puzzle even for secondary students.
• Pearl Oberon,
•
• Why are there only 2 solutions?
• Nancy, NY
•
• I found only 2 solutions. How is it 10? only 1, 3, and 5 can go on the outside of the circle. And only 1 and 5 could be placed in the outsides of the 4 linked numbers, that leaves us with 1, 4, 2, 5 and 3 or 5, 2, 4, 1 and 3. How is that it has 10 combinations?
• Mr Cansdale, Wintringham Grimsby
•
• 10Y3 think this is the most amazing thing they have ever attempted!
• Steve Eastop, Kent, UK
•
• Please note there is another solution: (reading down the page and left to right):
2
1 - 4 - 5
3.
• Matt, Burton On Trent
•
• I only found 2 also, cannot see how you can get anymore.
• M Trainor, Edinburgh
•
• My class absolutlely loved this!!!! They said it was too easy for them.
• Jimbobaloola, NKS6
•
• S.E, Can you please check your answers before entering incorrect info. There are Year 6 pupils here in Fulham who have proved that there are only 2 answers. Many thanks.
• Mr Cansdale, Oasis Wintringham Academy
•
• 7A4, the majority think that there are more than 2 ways of doing this!
• 9C1, Titus Salt School
•
• Emily said it's obvious. 1 3 and 5 have to go on the outside. So there can only be 2 solutions.
• Miss Clarke, Holton - Le - Clay Juniors
•
• We thought this activity was fun because it was challenging.
Chloe said she learnt a new word doing this activity - 'consecutive'.
Some of us found it a little confusing when arranging the numbers but we found the right answers in the end!
Shaun wants us to try and make our own up now.
• Kartik, India
•
• Hey Kids,
There are 12 ways in total.
In outer ring 1,3 and 5 can be arrange in 3! ways that is 6 different ways and 2 and 4 can be arrange in 2 ways there for 6 * 2 = 12 different ways.
• Kartik, India
•
• Its 2 ways sorry about previous answers as I forgot abt consecutive thing.
• Mr Pierce, 10R1 - Liverpool
•
• Absolutely AMAZING!!!!!!!!!!!! Found all 8 solutions.
• Mike M, Swansea
•
• Really great. Two solutions possible: Either (from top round clockwise) 1 , 3, 5, 2, 4 or 5, 3, 1, 4, 2. Class loved it.

Christmas Present Ideas

It is often very difficult choosing Christmas presents for family and friends but so here are some seasonal, mathematics-related gifts chosen and recommended by Transum Mathematics.

## Equate board game

Here's a great board game that will give any family with school-aged kids hours of worthwhile fun. Christmas is a time for board games but this one will still be useful at any time of year. Games can be adapted to suit many levels of Mathematical ability.

For Maths tutors working with just one or small groups of pupils this game has proved to be an excellent activity for a tutorial. Deciding on the best moves can spark pertinent discussions about mathematical concepts.

Equate looks a bit like Scrabble--for aspiring mathematicians, that is. Designed by a real mathematician, it works like this: You put down tiles on a board and make points by correctly completing simple equations. Your nine tiles include both numbers and mathematical symbols; you can add on to previous plays both vertically and horizontally. more...

## How Not To Be Wrong

The maths we learn in school can seem like an abstract set of rules, laid down by the ancients and not to be questioned. In fact, Jordan Ellenberg shows us, maths touches on everything we do, and a little mathematical knowledge reveals the hidden structures that lie beneath the world's messy and chaotic surface. In How Not to be Wrong, Ellenberg explores the mathematician's method of analyzing life, from the everyday to the cosmic, showing us which numbers to defend, which ones to ignore, and when to change the equation entirely. Along the way, he explains calculus in a single page, describes Gödel's theorem using only one-syllable words, and reveals how early you actually need to get to the airport.

What more could the inquisitive adult want for Christmas? This book makes a cosy, interesting read in front of the fire on those cold winter evenings. more...

## Graphic Display Calculator

This handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TI-Nspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TI-Nspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others.

For the young people in your life it is a great investment. Bought as a Christmas present but useful for many years to come as the young person turns into an A-level candidate then works their way through university. more...

The analytics show that more and more people are accessing Transum Mathematics via an iPad as it is so portable and responsive. The iPad has so many other uses in addition to solving Transum's puzzles and challenges and it would make an excellent gift for anyone.

The redesigned Retina display is as stunning to look at as it is to touch. It all comes with iOS, the world's most advanced mobile operating system. iPad Pro. Everything you want modern computing to be. more...

## Aristotle's Number Puzzle

It’s a bit of a tradition to give puzzles as Christmas Gifts to nieces and nephews. This puzzle is ideal for the keen puzzle solver who would like a challenge that will continue over the festive period (at least!).

This number puzzle involves nineteen numbers arranged into a hexagon. The goal of the puzzle is to rearrange the numbers so each of the fifteen rows add up to 38. It comes in a wooden style with an antique, aged look.

## Christmas Maths

This book provides a wealth of fun activities with a Christmas theme. Each photocopiable worksheet is matched to the Numeracy Strategy and compatible with the Scottish 5-14 Guidelines. This series is designed for busy teachers in the late Autumn term who are desperate for materials that are relevant and interesting and that can be completed with minimun supervision.

All the activities are suitable for use by class teachers, supply teachers, SEN teachers and classroom assistants and cover topics such as 'How many partridges did the true love give all together?' and 'Filling a sleigh with presents by rolling a dice!'. Children will have lots of fun working through the Christmas Maths themes but also gain valuable skills along the way.

A great source of ideas and another reasonably priced stocking filler. more...

If you teach mathematics to any age group in any country, you are guaranteed to learn lots of new things from this delightful book. It will deepen your subject knowledge and enhance your teaching, whatever your existing level of expertise. It will inspire you to explore new approaches with your pupils and provide valuable guidance on explanations and misconceptions. more...

I had been tutoring the wonderful Betsy for five years. When the day came for our last ever session together before the end of her Year 13, I received this beautiful book as a gift of appreciation.

This a very readable book by Ben Orlin. I'm really enjoying the humour in the writing and the drawings are great.

Ben Orlin answers maths' three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone. more...
