*This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 6 and 7 in year 2. Specifically this quiz is aimed at the section dealing with recognising the place value of each digit in a two-digit number (tens, ones) and partitioning numbers in different ways.*

Partitioning numbers means being able to recognise the value of each digit within a number given by its place, and separate or 'split' the number into its component parts. For example, 23 could be partitioned into place values of 20 and 3 (2 tens and 3 units), and 456 could be partitioned into 400, 50 and 6 (4 hundreds, 5 tens and 6 units). Partitioning can also be done in different ways - for example, 23 could be partitioned into 13 and 10.

Try this quiz to see how well you do with partitioning numbers.
