Dividing a Number into Groups (Example)

The video tutorial demonstrates how to divide 28 marbles into four equal groups. It begins by drawing rectangles to represent each group and then distributes the marbles equally among them. The process is repeated until all marbles are distributed, resulting in each group having 7 marbles. This is expressed as 28 divided by 4 equals 7.
