About the activity

These activities involve both Part-Whole and Comparison Bar Models as representations of word problems involving both the sum or difference of quantities. These models aid extracting the information from the problem, representing it pictorially, and visualising the solution process.

The models are also useful for solving problems where the quantities made up of equal parts, and thus also for representing fractions, decimals and percentages.

The development of these bar model activities was inspired by William Emeny's Great Maths Teaching Ideas blog entry Bar modelling—a powerful visual approach for introducing number topics.
