### Division

Short division – Six examples of dividing numbers using the short, or what is sometimes called the bus stop method. The examples progress in difficulty with the first two examples not requiring any remainders, the next two examples having remainders within the calculation and the last two examples having...

### Fractions: The Basics

What are fractions? The basics – This video covers the basics of fractions beginning with the definition of the numerator and the denominator. Simple examples are given to illustrate that fractions are a way of describing proportion. There follows an explanation of how a fraction also represents a...

Adding and subtracting fractions with the same denominator – This video begins by showing the common mistake of adding the numerator and adding the denominator and explaining why this cannot be correct. The correct method is used with a pictorial representation to aid understanding. The video continues with a...

### Introduction to Graph Transformations

[b]Introduction to graph transformations [/b] – The video begins by suggesting that all graphs in a family are related in some way. There follows a useful explanation of function notation linking the notation to the inputs and outputs of a function machine.

The four graph transformations; translate...

### Maths and Art

Curves of pursuit – This video demonstrates how to construct curves of pursuit. Beginning by drawing a square, students are taken through the required steps. The video ends by suggesting different shapes as starting points.

Sequence designs – Beginning with the sequence of square numbers, a new...

### Factors, Multiples and Primes

Factors – Beginning with the definition of what a factor is this video proceeds to find the factors of 12 with the aid of a factor bug. The factor bug is a visually stimulating method of finding factors and suitable for use with younger students. After finding the factors of 18, the factors of 17 are found....

### Highest Common Factors and Lowest Common Multiples

Highest common factor and lowest common multiple – The first example finds the highest common factor of 6 and 15 by listing all the factors of each number, highlighting all the common factors and indicating the highest common factor. A similar technique is used to find the lowest common multiple of 6 and 15....

### Stretches

[b]Stretch parallel to the y axis [/b] – looks at what happens to the graph of y=f(x) when it is transformed to give the graph of y=af(x). Starting with the graph of y = x[sup]2[/sup], different values of a are used to show that the graph is stretched from the x axis parallel to the y axis. The next example...

### Translations

[b]Translate parallel to the y axis [/b] – looks at what happens to the graph of y=f(x) when it is transformed to give the graph of y=f(x)±a. Starting with the graph of y = x[sup]2[/sup], different values of a are added or subtracted to the graph. The explanation continues to show that the graph is translated...
