I teach Maths to 10 - 13 year old children and these resources are aimed at them! I have also written a book called, "The Aliens have landed and 174 other problems" which is available from either Amazon or The Mathematical Association. It is full of mathematical puzzles. http://members.m-a.org.uk/Shop

A cut out Pascal's Triangle for a display board

(4)
Pascal's Triangle is a wonderful starting point for introducing or discovering lots of number patterns including the triangle numbers, the Fibonacci sequence, the doubling sequence and many more. There are 20 pieces which need assembling to make 16 rows of the triangle with spare pieces for extra rows. Each piece needs cutting out and ideally laminating. It would make a fun activity to just piece it together! It can be printed out on A3 paper to fill a display board or on A4 paper for a smaller version. The title and questions are also included.

Cubic numbers and Triangular numbers

For display in the classroom - the cubic numbers and triangular numbers. You can print them out twice and stick them back to back, laminate them and either create a mobile or hang them on a string across the classroom.
The rope around the earth problem explained!

The rope around the earth problem explained!

(0)
This is a brief power point presentation to demonstrate the solution to the well know rope around the earth problem: if a rope goes all the way around the equator, how much more rope is needed to lift the rope exactly one metre above the surface of the earth? The answer is an extraordinary and completely counter-intuitive one! It is in fact just 6.28 metres and it is exactly the same answer, whether the question is talking about a football or the earth!
How to calculate the number of Enigma machine settings explaining combinations and permutations.

How to calculate the number of Enigma machine settings explaining combinations and permutations.

(0)
This is an 8 page booklet which takes the pupils through the maths of calculating the number of ways an Enigma machine can be set up, using both permutations (the order of the rotors does matter) and combinations, where the order in which the plug board is set up doesn't matter. The first two pages lead the pupils through the various calculations leading to the answer of approximately 158 million billion ways or 158,962,555,217,826,360,000 ways to be precise! The remaining six pages explain the difference between permutations and combinations.
The Fibonacci Sequence in Pascal's Triange and other patterns

The Fibonacci Sequence in Pascal's Triange and other patterns

(0)
This is a poster of six images of Pascal's Triangle with a number pattern highlighted in each image: The Fibonacci Sequence, The Doubling Sequence, The Odds and Evens and Multiples of 3, 5 and 7. It would make a very good poster for the wall or for students to have in their books - the six sheets can be printed out onto one sheet of A4 paper for a mini version.

Top Trumps for 2D Maths shapes

(0)
This is a Top Trumps card game with 16 different shapes, which each have various properties. For example, the isosceles triangle has 3 sides, 2 equal sides, 2 equal angles, 0 right angles, 0 pairs of parallel lines, 1 line of symmetry and order of rotational symmetry of 1. It also has a special feature: it is hard to spell correctly! It also has a rating of 2 out of 10.

A presentation to explain the well known birthday problem!

(0)
How many people do you need to have in the same room before it is more likely than not that two people share the same birthday? The answer is surprisingly counter intuitive and in fact it is only 23! This 21 slide power point presentation explains the mathematics behind this answer. Pupils only really need to know how to calculate basic probabilities to appreciate this presentation.
