57p=0.57

3 lots of milk

3 x 0.57 = 1.71

Angles around a point add up to 360⁰.

In geometry, a right angle is shown by a small square.

A right angle equal to 90⁰.

This fact can be used to calculate unknown angles.

360 - (120+90) = y

360 - 210 = y

150 = y

Number sequences are sets of numbers that follow a pattern or a rule.

If the rule is to add or subtract a number each time, it is called an arithmetic sequence.

If the rule is to multiply or divide by a number each time, it is called a geometric sequence.

Each number in a sequence is called a term.

A sequence which increases or decreases by the same amount each time is called a linear sequence.

Harry : 9 x 7 = £63

Carly : 11 x 6 = £66

Carly earns £3 more.

The diameter of a circle is the distance from one side of a circle to the other through the centre.

The radius is the distance from the edge of the circle to the centre.

The diameter is twice as long as the radius.

A portion of chips cost 80p.

80 $$\div$$ 5 = 16.

16 pieces

A pie chart is a chart represented by a circle. It shows the proportion of each group at a glance.

In a pie chart it is important to understand that the angle of each sector represents the fraction, out of 360, assigned to that data value.

Remember that a small square represents 90° or a quarter .

$$\frac{1}{4}\times60\ =15$$ or $$\frac{90}{360}\times60\ =15$$

3-dimensional (3D) shapes are solid shapes. They have 3 dimensions - length, width and height.

Some 3D shapes have faces, edges and vertices.

Some 3D solids, such as the cone and the cylinder, have faces and curved surfaces.

Some 3D solids, like the sphere, just have a curved surface.

Fractions are one way of showing numbers that are parts of a whole. Other ways are decimals and percentages.

Equivalent fractions are fractions that are worth exactly the same even though they are written differently.

$$\frac{20}{30}=\frac{2}{3}$$
