•
• I thought that this was a great starter for us all to use trying to see if they will slot into place nicely.our teacher got this answer wrong before he was corrected.
• Ava Godsy, North Glendale
•
• I really liked this game because it was fun and easy to understand. I like making charts and graphs and thinking about numbers in different ways.
• Mrs Martin's Class, 7abM4
•
• Once you have some of the numbers in the grid it is really easy to put the others in place.
• Bob, Medway
•
• This doesn't work. 2 belongs in two places as does 6. 2 is prime, a factor of 168 and even. 6 is a multiple of 3, it's a factor of 168 and it's even. Unless you actually want to start a discussion about the validity of graphs, I really wouldn't use this.
• Anne Carlill, Leeds City College
•
• This has been my most successful starter yet! I can't understand why anyone would be negative about it. It really gets students to retrieve what they know about square nos and primes. Thank you!
• Gina, Derbyshire
•
• Of course it works! Not only that, there is only one solution; let's not forget that logic is a vital part of maths too. This is one of my favourite starters and can lead to all sorts of valuble discussions.
• Y6 Dream Team, Tickhill St. Mary's
•
• We'd like to see more of these.
• Dean Westbourne, Midlands
•
• Bob look at the big picture, yes some can fit in more than one place but pupils have to realise that all have to be used once as it states in the instructions! so I disagree with your comment it 'does work!'.
• Josh Hand, King's Worcester
•
• Dear Bob
My Class of Year 9s managed to complete this starter. It is possible. Take a logic class!

•
• We found this really easy. We would love more of a challenge!
[Transum: Well Charnwood, if you would like more of a challenge try Satisfaction].
• The Kiefer Kids, Cottage Hill
•
• Congratulations to Bailey, Cade, Katelin, and Jessica for solving this brain buster!
• 5F JPs, Mr.C
•
• It was a good challenge for the children, not too hard not too easy. It also made us revise our understanding of 6 different mathematical terms.
• Mr C, East Tuddenham
•
• We are confused, 1 is not a square number so we can not find a place for it, please send us the correct solution for our perusal.

[Transum: Sorry Mr C, the answers are only available to subscribers. Have you considered subscribing? By the way one is a square number.]

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 Christmas gift for anyone.

You have to hold iPad Air to believe it. It’s just 7.5 millimeters thin and weighs just one pound. The stunning Retina display sits inside thinner bezels, so all you see is your content. And an incredible amount of power lies inside the sleek enclosure. So you can do so much more. With so much less. 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.

Keep the Maths in Christmaths with this reasonably priced stocking filler. more...

## The Story Of Maths [DVD]

The films in this ambitious series offer clear, accessible explanations of important mathematical ideas but are also packed with engaging anecdotes, fascinating biographical details, and pivotal episodes in the lives of the great mathematicians. Engaging, enlightening and entertaining, the series gives viewers new and often surprising insights into the central importance of mathematics, establishing this discipline to be one of humanity s greatest cultural achievements. This DVD contains all four programmes from the BBC series.

Marcus du Sautoy's wonderful programmes make a perfect Christmas gift more...
