Place value is very often one of the first units of work for maths in most year groups and is absolutely fundamental to a good understanding of number. By getting this right and giving children the opportunity for deep conceptual understanding, we can lay solid foundations for the year.
For the purpose of this blog I’m going to assume that children can count reliably and read and write numbers without error. If these things are not yet developed to the appropriate standard then targeted intervention needs to happen without the child missing out on good modelling and explanations of place value.
Children need plenty of practice constructing and deconstructing numbers, first using concrete manipulatives like base ten blocks or Numicon. This is to show that 10 ones is equivalent to 1 ten etc. While they’re making these numbers they should be supported to talk articulately about what they are doing, perhaps with speaking frames: ‘This number is 45. It has 4 tens and 5 ones. 45 is equal to 40 add 5.’
