Addition

Pupils are taught to add numbers using the column method

Using similar methods, children will;
add several numbers with different numbers of digits
Begin to add two or more decimal numbers with a different number of digits e.g. 12.78 + 5.9
Know that decimal points should line up under each other, particularly when adding or subtracting mixed amounts, e.g. 401.2 + 26.85 + 0.71

Subtraction

As with addition, pupils are expected to use the column method for subtraction also.
With decimals:
Don’t forget to add a zero when it is needed,

Multiplication

Pupils are encouraged to multiply numbers in columns.

This then moves on to multiplying larger numbers and decimals (this is where pupils can struggle):

The most common error here is remembering to put in a zero when multiplying by the tens digit.

Division

Pupils are encouraged to use short division.

This then gets extended to dividing numbers to get a decimal answer.

When dividing by a two digit number pupils are encouraged to use short division and to have the first 9 multiples of the divisor (number to be divided by) written out to help them.
