You can change a fraction into a decimal by dividing the top number by the bottom.
Long Multiplication
Long multiplication breaks a big multiplication into steps.
Long Division
Long division splits a large number into equal groups.
Times Tables Tricks
Some times tables have patterns that make them easier to remember.
Divisibility Rules
A divisibility rule tells you quickly whether a number can be divided by another without a remainder.
Powers and Exponents

Square Roots
The square root of a number is the value that, multiplied by itself, gives that number.
Cube Numbers
A cube number is made by multiplying a number by itself three times.

The Pythagorean Theorem
In a right-angled triangle, the square of the longest side equals the sum of the squares of the other two sides.
Area of a Triangle
The area of a triangle is half of its base multiplied by its height.
Capacity and Litres
Capacity is how much a container can hold.
Unit Conversion
Converting units means changing a measurement into another unit of the same type.
Fraction of an Amount
To find a fraction of a number, divide the number by the bottom number, then multiply by the top number.
Number Bonds
Number bonds show pairs of numbers that add up to a total.
Fibonacci Numbers
The Fibonacci sequence starts with 0 and 1, and each new number is the sum of the two before it.
Pi
Pi is the number you get when you divide the circumference of any circle by its diameter.
Reflection in Maths
A reflection flips a shape over a line called the mirror line, so that each point is the same distance from the line on the opposite side.
Rotation
A rotation turns a shape around a fixed point called the centre of rotation.
Mental Maths Strategies
Mental maths means calculating in your head.
