See above ten phrases which need to be memorised. Each time the blue play button is clicked a phrase will be removed from the collection. The aim of the activity is to write down the exact the phrase after it has been removed. After the last phrase has been removed all ten phrases are then shown in the order they were removed so that accuracy can be checked. The auto play button removes phrases at thirty second intervals (the time interval can be changed  see below).

The phrases, in the order they disappeared, will be shown in the panel at the top of this page at the end of the game.
Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

For many pupils the initial task of memorising ten items is far too difficult. You can make the game easier by removing some of the items with the blue button before you present the pupils with this activity.
The auto play feature removes phrases after a certain number of seconds (30 seconds by default). You can vary that time interval if it is not suitable for your class here:
Auto Play: Remove phrases every
Note that the first phrase is removed four seconds after pressing the auto play button despite the time interval set for the rest of the phrases above.
Christmas Present Ideas
It is often very difficult choosing Christmas presents for family and friends but so here are some seasonal, mathematicsrelated gifts chosen and recommended by Transum Mathematics.
Equate board gameHere's a great board game that will give any family with schoolaged 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 Scrabblefor 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 WrongThe 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 onesyllable 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 CalculatorThis 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. TINspire 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 TINspire, 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 Alevel candidate then works their way through university. more... 
Apple iPad ProThe analytics show that more and more people are accessing Transum Mathematics via an iPad as it is so portable and responsive.

Christmas MathsThis 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 514 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...

Math with Bad DrawingsI 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 formscartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone. more...

Teacher, do your students have access to computers such as tablets, iPads or Laptops? This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments: Transum.org/go/?Start=September11 However it would be better to assign one of the student interactive activities below. 

Here is the URL which will take them to a student version of this activity.
If you are not familiar with Rudyard Kipling's story of Kim, or, to give him his full name, Kimball O'Hara, he was the son of a sergeant of an Irish regiment in India in the late 1800s. His father and mother died while he was a child, and he was left to the care of an aunt.
His playmates were all local Indian boys, so he learned to talk their language and to know their ways. He became great friends with an old wandering priest and travelled with him all over northern India. One day he chanced to meet his father's old regiment on the march, but in visiting the camp he was arrested on suspicion of being a thief. His birth certificate and other papers were found on him, and the regiment, seeing that he had belonged to them, took charge of him, and started to educate him. But whenever he could get away for holidays, Kim dressed himself in Indian clothes, and went among the locals as one of them.
After a time he became acquainted with a Mr Lurgan, a dealer in old jewellery and curiosities,who was also a member of the Government Intelligence Department. This man, finding that Kim had such special knowledge of local habits and customs, decided that he could make a useful agent for Government Intelligence work. He therefore gave Kim lessons at noticing and remembering small details, which is an important point in the training of a Scout.
Mr Lurgan began by showing Kim a tray full of precious stones of different kinds. He let him look at it for a minute, then covered it with a cloth, and asked him to state how many stones and what sorts were there. At first Kim could remember only a few, and could not describe them very accurately, but with a little practice he soon was able to remember them all quite well.
At last, after much other training, Kim was made a member of the Secret Service, and was given a secret sign, a locket to wear round his neck and a certain sentence, which, if said in a special way, meant he was one of the Service.
