An array model helps visualize a multiplication equation as a collection of objects organized in rows and columns. Array models are similar to area models; however, while array models represent objects organized in rows and columns, area models are always depicted as a grid or rectangle.
To use an array model for multiplication, follow these steps:
- Arrange objects in a column with the number of objects equal to the first number.
- Repeat this process in the amount equal to the second number.
- The total number of objects in the array represents the product of the two numbers.
For example, let's consider the multiplication equation 2 × 3:
- Arrange 2 objects in a column.
- Since the second number is 3, arrange two additional columns of 2 objects directly to the right of the first column.
- Count the number of units in the array to determine the product of 2 and 3 (6)
