KS4 Maths – Foundation

Please click on the links below to find out more about each unit.

Year Long Term Objective: To Build upon the foundation laid in KS3 to prepare students for the rigours of the GCSE. Students should be stretched with challenging GCSE style questions routinely.
Year Autumn 1 Autumn 2 Spring 1  Spring 2 Summer 1 Summer 2
Medium Term Objective: Autumn: Recap and extend students on fundamental number and algebra work. Spring: Work on geometry, while stretching students by interleaving with number and algebra exam problems. Summer: Enhance students proportional reasoning skills and develop ability at harder exam questions.

Example Key Words


A change in the position, size or shape of a figure


This changes the position of a shape


This flips the shape over – it is the mirror image


Turning a shape around a fixed point.


This changes the size of the shape – it can make it smaller.

Scale factor

This defines how many times bigger or smaller an enlagement makes a shape.

Right Angled Triangles


– Pythagoras’ theorem

– Trigonometry: the sine ratio
– Trigonometry: the cosine ratio

– Trigonometry: the tangent ratio

Example Key Words


The longest side of a triangle. It is also the side opposite the right angle.

Pythagoras' Theorem

A theorem stating that in a right triangle the area of the square on the hypotenuse is equal to the sum of the areas of the squares drawn on the other two sides.

Opposite and adjacent side Side

The side opposite (opposite) and next to (adjacent) the angle you are dealing with in a triangle (not the right angle)

The Sine ratio

The sine of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to that of the hypotenuse.

The Cosine ratio

The cosine of an angle in a right triangle is defined as the ratio of the length of the side adjacent to the angle to that of the hypotenuse.

The Tangent ratio

The tangent of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to that of the adjacent side.
