New Comprehensive Tool for Generating Bar Models in Singapore Math

It’s important to remember the principles of the Singapore methodology, which is based on three phases: concrete, pictorial, and abstract. Within this approach, being familiar with the pictorial phase is essential, as it involves using bar models to solve mathematical problems.

To facilitate the creation of exercises using this model, a new tool has been developed.

The first section of the tool allows you to configure the number of bars, columns, and rows, as well as to add more bars to each exercise and divide the bars into parts. It also enables proportional scaling, which can be tricky when working with zero, and offers options for using brackets. This initial setup is designed to customize the exercise worksheet.

The second section allows you to hide or show the total, making it easier to perform operations such as addition, subtraction, multiplication, or division.

The third section enables the display of equal parts, which, if activated, indicates multiplication or division; if not, it suggests addition or subtraction, depending on the previous setting to hide the total. This section also offers the option to display the number of parts, turning the exercise into a fraction of a quantity problem.

Finally, the tool includes controls for the addends and factors used in calculations.

Once the exercise is configured, you can take several actions: create new data based on the selected configuration, generate a random configuration, print or download the exercise as a PDF, and display the results.

In summary, this tool is an excellent resource for generating bar models in mathematics. We hope you find it useful.
