YEAR 1, Addition and Subtraction - Calculations (1C4)

Car Park Problems

1C4: Solve one-step problems that involve addition and subtraction, using concrete objects, pictorial representations, and missing number problems such as 7= …. - 9

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

Count reliably at least 20 objects, recognising that the number of objects stays the same when rearranged; estimate a number of objects that can be checked by counting

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
