Mistake: Pupils may not see that larger numbers can be composed in different ways. Correction: Use place value charts to show pupils how numbers can be composed in different ways (e.g. 1700 = 17 hundreds, 170 tens or 1700 ones). Make clear links to how we can read the number and how this helps us to describe what it is composed of.
