Now that bar modelling is a staple of classrooms across the UK, we thought it was time to show you how we here at Third Space Learning use this pictorial representation within our 1-to-1 intervention lessons. The aim is to give you a few ideas of how you can use it too no matter what primary school year you teach maths to. Bar models for all we say! 

For those of a certain generation (and I include myself in this) maths was taught by working out page after page of calculations until the theory behind what you were doing got hammered into your brain through constant repetition.

The idea of using pictures as part of teaching maths was a rarity, but one idea that was introduced in the 1960s is now coming back into fashion in a big way – bar models!

If you are unsure as to what they are, or perhaps need a reminder of just how effective the humble bar model can be, our excellent resources The Ultimate Guide to Bar Modelling will tell you.

History Of Bar Modelling
An extract from the Ultimate Guide to Bar Modelling on the history of this method of pictorial representation.

It also goes through in great detail:

• What bar models are

• The benefits of using them

• How to introduce them into your school

• Which types of maths problems they can help you to solve 

• Much, much more!

How We Use Bar Models 

What I want to do in this post is outline how we use bar models here at Third Space Learning and how alongside our 1-to-1 learning platform, the resources we have created could be effectively used to improve your teaching.

Here at TSL the bar model pops up not only our blog posts (read this on bar models for SATs and this for some step by step guidance on how to teach bar modelling) and classroom resources, but also in our CPD video library.

The core of the Third Space Learning offer is of course the pedagogy behind our 1-to-1 intervention lessons, because we are able to gauge immediately after every lesson, how successful it was and what we could do to improve it. In any week up to 6,000 pupils will be receiving one of our 270 lessons, and we record every lesson a child receives from their tutor so we can look back and review where and how progress was made or additional scaffolding was required. 

Since we started teaching 1-to-1 online in 2014 we’ve vastly increased the pictorial representations we use. Like many schools following a mastery approach to maths, we find that they just help children to develop deeper conceptual understanding. And far and away, the bar model is the best of the tools we use!

How We Use Bar Models In Our 1-to-1 Maths Intervention Lessons

Bar modelling can be used to help teach many topics in maths, from adding and subtracting numbers through to fractions to ratios. Their versatility is one of their strongest points in your classroom, and our online one too!

Bar models are particularly useful if lessons where greater explanation is needed.  Here are the bar model methods we use across the maths curriculum to teach key topics.

Using the Bar Model to teach fractions

From lessons on Simple equivalent fractions to Adding and Subtracting all kinds of fractions to Fraction problems, this topic is made more visual and easier to understand by simply inserting bar models into the lessons.

The nature of fractions makes the bar model the perfect way to teach them, and pupils often dividing a bar into the appropriate fraction very simple.

Our interactive learning platform means that no matter what question comes up, or what the conversation is that follows on from a question, both tutor and pupil are free to create their own bar model to help cement the point at hand.

You may not have even known you were using a bar model when teaching fractions.

Hands up all those teachers who’ve used a fraction wall?

Using the Bar Model to teach ratio and rates

Another pair of topics that lend themselves to the bar model well, ratio and rate based questions can be presented easily in a visual manner as a way to help pupils solve problems. As shown in the example below, by breaking the problem down in such a way, our tutors can explain the problem step-by-step to help ensure that the point has come across.

Using the Bar Model with word and number problems, estimating and decimals

Bar models are incredibly useful when working out SATs style word problems or calculations involving number problems, estimation or decimals. A bar model allows you to ‘unpack’ the question and set it out visually so that the child can see the difference in size of the bar models, depending on the size of the number, which can then help them to work out what the question is asking them to do.

Why We Don’t Use Bar Models For Every Topic

Crucially, we have only used bar models in a selection of lessons, as using them in every lesson would not only devalue their importance, but make pupils think that they are the only way to work out every problem.

While bar models can be used for most topics in maths, including multi-step maths word problems, they are only one weapon that a pupil should have in their arsenal.

Our Use Of Bar Models In Our Videos

If you explore the Third Space Learning Maths Hub, you will find that one of the topics is entitled Bar Models. Click on this and you will find over 30 videos on how to use bar models to teach a variety of subjects, from solving percentage problems to complex KS2 multiplicative problems, as well as videos explaining the basics of bar models and how to introduce them into Year 6.

Bar Model Videos On The Maths Hub

These videos are quick, usually being a few minutes long which means that they are great for teachers and children alike.

How you can use these bar modelling videos

As a teacher, you can use these videos whilst planning your lessons, to give you ideas about how to teach the topic or as a new way to approach the subject.

They can be used within lessons as starters, reminders or as part of a flipped learning platform, with pupils watching them at home, ready to use these skills to solve problems in class.

As mentioned, the collection of 34 videos we have on the Maths Hub on bar modelling covers a wide range of topics, and some of the subjects you will find covered include:

How We Use The Bar Model In Our Teacher Training

As part of their training to become tutors for Third Space Learning, our videos and lessons are used as materials to introduce them to the concept of bar models and how they can be effectively used to teach topics in maths.

As we at Third Space Learning consider bar modelling to be an important aid to excellent teaching, we created a tool that a tutor can use during a teaching session to create their own bar models.

Bar Modelling being used by maths tutors

The square button allows the tutor to quickly create bars to aid their teaching, which can be shaped to the size the tutor requires, whether it is being used for a part/whole or comparison bar model.

The button can even be used by the pupil with the instruction of the tutor, allowing them to try and create their own bar model to help them solve the problem they are attempting.

This continues into our post-session questions, where bar models are used as a pictorial guide to help pupils work out the problem they have been given.

Again, like with our lessons, bar models are used sparingly so that pupils can use a range of different methods. However, the lessons that use bar models will have post-session questions with bar models, so as to demonstrate their importance for that particular topic.

Why We Use Bar Models In Our Lessons

At Third Space Learning, we support the focus on helping children master the topics they are taught in maths, and our adoption of bar models across our various resources demonstrates our desire to give children every tool they need to tackle the maths problems they face.

However, as stated earlier, bar models are just one way of teaching maths topics, not the only way, and it is not up to us to tell teachers what method they should use. Some teachers may already make great use of bar models in their teaching and our resources will be useful as a reminder or handy tool to use in a particular lesson they might have been struggling with.

New teachers, or teachers new to the idea of bar models, will find our resources will explain to them how important bar models can be and start to guide them into how and where they can be used.

How To Introduce Bar Modelling Into Your School
Another snippet from the Ultimate Guide To Bar Modelling

Our goal at Third Space Learning is to not only provide world class 1-to-1 tuition via our interventions, but to make pupils confident and well-rounded learners, utilising as many methods and ideas as possible to solve any problem they are given.

Bar models allow pupils to become more involved in their learning and as Benjamin Franklin said:

“Tell me and I forget. Teach me and I remember. Involve me and I learn.”

Things To Take-Aways From This Blog

If you are in a rush, these five points summarise what we think about the bar model:

• Bar models are an excellent way of visually portraying a problem, making it easier for pupils to understand what they are being asked to do.

• Bar models should be used as one example of methods to solve problems, and are especially useful for certain topics, such as fractions, ratios or missing number problems.

• Bar models can be used with children of any age group or ability, on a variety of mediums, from videos to whiteboards to multi-link cubes.

• Bar models are especially useful when teaching pupils with learning difficulties or special needs, who might respond better to visual prompts.

• Bar models form an important part of our 1-to-1 lessons as they give us a great chance to help pupils solve their problems in a visual manner. This can be replicated easily in the classroom too.
