16. Building conceptual understanding through CPA .
Emphasise that the bar model is one representation that helps to structure children’s thinking in problem solving
The example from the White Rose calculation document shows this as part of a concrete- pictorial – abstract ‘journey .

17. As a primary maths coordinator, it's been difficult to escape the lure of bar modelling: it's in every new publication, on all the maths blogs and at every coordinator's meeting. And so, when the time was right for my school, I succumbed.
Bar modelling, for the uninitiated, is not a method of calculation. Instead, it is a way of representing problems pictorially: from simple addition, through to finding percentages of amounts, all the way to complex multi-step problems involving ratio and proportion. Bar models can be used to pictorially represent arithmetic problems, as well as reasoning problems written with a context.
The reading comprehension involved in problem-solving hampers our children, and while bar modelling doesn't remove the necessity to read and comprehend maths problems, it certainly provides a structured way of working through a written problem.

18. As a school we have invested in specialist staff training from Nathan Crook for all teaching staff.
We are running a bar modelling week within school.
We have a display on ‘Barvember’ which features work done by children.
