Understand subtraction as 'take away' and find a 'difference' by counting up; use practical and informal written methods to support the subtraction of a one-digit number from a one-digit or two-digit number and a multiple of ten from a two-digit number

Relate addition to counting on; recognise that
addition can be done in any order; use practical
and informal written methods to support the
addition of a one-digit number or a multiple of
ten to a one-digit or two-digit number

Use the symbols +, – and = to record and
interpret number sentences involving all four
operations; calculate the value of an unknown in a number sentence (e.g. ?? + 2 = 6, 30 – ?? = 24)
