Recognise the place value of each digit in three-digit numbers, and compose and decompose three-digit numbers (2)

Description

Pupils should be able to identify the place value of each digit in a three-digit number. They must be able to combine units of ones, tens and hundreds to compose three-digit numbers, and partition three-digit numbers into these units. Pupils need to experience variation in the order of presentation of the units, so that they understand that 40 + 300 + 2  is equal to 342, not 432.
