Teaching with Bar Models: The Fundamentals


Bar models are a powerful model to have at your disposal in the mathematics classroom. They offer a conceptual approach to communicating some key 'big ideas' in mathematics.

In this course we will venture through arithmetic, percentages, fractions and equations and culminate in using bar modelling to make better sense of what would typically be, tricky worded problems.

Course Content

In this section of the course, we will explore what bar models are and look at some simple examples of how they can be used in your classroom.
In this section, we look at how bar models can be used to communicate some key ideas within the topic of place value. 
Fractions are a challenging idea to communicate, but with bar models, we can do this in a far more impactful way. We will look at identifying fractions, comparing fractions, equivalence, and operations with fractions.
Bar models are a clear and intuitive way in which to communicate to pupils what percentages are and relating them to decimals and fractions. We will look at identifying percentages, percentages of amounts, increasing/decreasing percentages, compound interest, and reversing percentages.
