Dividing 54 into Groups

The video tutorial demonstrates how to use the bar model for solving multiplication and division problems. It starts with a multiplication example of six times nine, illustrating how to represent it using a bar model. The tutorial then transitions to a division example, where a total of 54 is divided into six groups, showing how to determine the value of each group. Finally, it covers a scenario where the total and group value are known, but the number of groups is unknown, and explains how to calculate it using the bar model.
