Begin to know what each digit in a two-digit number represents. Partition a 'teens' number and begin to partition large two-digit numbers into a multiple of 10 and ones (TU).
Within the range 0 to 30, say the number that is 1 or 10 more or less than any given number.
Recognise coins of different values. Find totals and change from up to 20p. Work out how to pay an exact sum using smaller coins.
Use mental strategies to solve simple problems set in 'real life' money or measurement contexts, using counting, addition, subtraction, doubling and halving, explaining methods and reasoning orally.
