New bar modelling content

We have released some new bar modelling lesson and homework activities on MyMaths.

Bar modelling is a valuable tool that helps children visualise parts of a maths problem. The step-by-step method can help children to understand and extract the information within a calculation or a word problem, and then translate this into a picture. This provides an important transition from the concrete to the abstract concepts in key stages 1 to 4.

With this in mind, we have created a suite of 8 new lessons and homework tasks in Primary MyMaths to support schools that are using, or would like to use, bar modelling. These include bar modelling for addition, subtraction, comparison, fractions, ratio and proportion, as well as a fantastic new number bonds lesson which lays the foundations for bar model work in later years. You can find this new content as follows:

Number bonds to 20 This lesson lays the foundations for later bar modelling work by using cubes, pictures and rods to represent number facts up to 20 and support the completion of number trios.

Find it in Library > Number > Addition and subtraction (English National Curriculum) or search ‘Number bonds’.

Adding and taking away This lesson builds on work using cubes and introduces bar models in the context of the ‘adding on’ structure for addition and the ‘taking away’ structure for subtraction. Modelling is used to solve one-step and multi-step problems involving these structures.

Find it in Library > Number > Addition and subtraction (English National Curriculum) or search ‘Taking away’.

Adding together This lesson introduces bar models in the context of the part-whole concept for addition and subtraction and uses modelling to support writing number sentences and solving multi-step problems.

Find it in Library > Number > Addition and subtraction (English National Curriculum) or search ‘Adding together’.

Comparing: find the difference This lesson introduces terms associated with comparison (more than, fewer than, difference) and uses them to describe sets of cubes. This knowledge assists the construction and use of bar models to solve multi-step problems according to the comparison structure for addtion and subtraction.

Find it in Library > Number > Addition and subtraction (English National Curriculum) or search ‘Difference’.

Comparing: how many times more? This lesson represents multiplication and division calculations using cubes and rods, before moving on to constructing bar models and using them to solve scaling problems where multiplication and division are involved.

Find it in Library > Number > Multiplication and division (English National Curriculum) or search ‘Times more’.

Modelling fractions of amounts This lesson explores finding fractions (half, one-quarter, one-third, three-quarters and two-thirds) of quantities and amounts by splitting a group of objects, dividing a block of cubes and using a bar model, and then applies this knowledge to solving word problems.

Find it in Library > Number > Fractions (English National Curriculum) or search ‘Modelling’.

Modelling fraction calculations This lesson models fractions using cubes and bars and then uses bar models to support adding and subtracting fractions with the same denominator (up to twelfths) and solving word problems involving these concepts.

Find it in: Library > Number > Fractions (English National Curriculum) or search ‘Modelling’.

Modelling ratio This lesson introduces using a bar model and the unitary method to find one or both quantities in a ratio, applying this knowledge to solving word problems. This is supported by first modelling ratio using groups of objects and arrays.

Find it in Library > Number > Ratio and proportion (English National Curriculum) or search ‘Modelling’.
