•
• 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.]
• Colette Timble, Brewster Ny
•
• How do I know if I’m correct.

[Transum: This version of Small Satisfaction is intended to be projected in front of a class. It will hopefully encourage discussion and when complete, beg the questions 'is that correct?' and 'is there any other way of doing it?'. The pupil version of this activity is self checking so that the pupil will know if they are correct. You can find that version here. Alternatively the answers to this version are available below for Transum Subscribers]

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...

## A Compendium Of Mathematical Methods

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...
