Partitioning numbers means being able to recognize 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.
