Partitioning in Year 4 Partitioning numbers is an important part of the new maths curriculum. In Year 4 children will be expected to partition numbers in the thousands into thousands, hundreds, tens and ones. For example: 4 560 can be written as 456 tens; 45 hundreds and 6 tens; 4 thousands and 56 tens and so on. Our latest sets of worksheets take a close look at partitioning and provide plenty of excellent practice. Go to Year 4 Number and Place Value
