• We found this quite easy but the class enjoyed it.
• 7O, Lord Lawson
•
• We found this very hard!
• Mrs O'Hagan's Firs yr class, Holyrood Sec School Glasgow
•
• We found this starter quite hard..and as we were given it for homework we were disappointed that as it was still the same day, the numbers were changed
• Mr Shaw, Beaulieu Convent Jersey Year 9
•
• We found this easier if we worked in teams. It took us 10 minutes to find our first answer.
• KGo, AHHC
•
• My Year 10s enjoyed this and thought more of these would be great.
• 7f1, John Port School
•
• We enjoyed this task very much. It was challenging sorting out the problem but fun!
• Mr. G, Beacon Community College, Crowborough
•
• A very good activity to encourage creative thinking. The first student to find a sum (Brandon Lawrence) did it after 5 trials and within 10 minutes on his own. Most of the students were happy to do this activity.
• Lizzie Lucas, Holcombe Brook Y5
•
• I think that there should be more of this on the website because it is good fun,me and my mum found it very easy with a little help from dad.
• Miss Hope, Castle Rushen High School
•
• We found this a bit of a challenge after starting off with different numbers making one of the totals. We got there in the end, after we took Robert's recommendation (We are in y13, age 17 :) ).
• Jack And Mrs Williams, 9PJH
•
• Very difficult but we cracked it! fun challenge.
• Jay, Ramsden Hall School
•
• Its okay but we found it confusing.
• Senan, Barnes Primary Year 6
•
• I really liked this problem. it took me about 3 minutes and I found it quite fun. I would like more of this sort of thing.
• P6/7s, Craiglockhart Primary, Edinburgh
•
• Our P6/7's (10/11 year olds) did this as a warm up to our Maths lesson. First solution found in 5 minutes.We found it fairly challenging but really got us thinking! We all enjoyed it.
• St Mark's School,
•
• Challenging but fun. My Year 5 class managed to complete this in 8 minutes. Team work helps!

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...

## Apple iPad Pro

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...

Before giving an iPad as a Christmas gift you could add a link to iPad Maths to the home screen.

## 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.

## 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...

## 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...
