Multiplying Decimals Using Visual Models

This lesson teaches how to multiply decimals using a visual model with a 10x10 array. By representing one decimal as rows and the other as columns, students learn to find the product by identifying the area shaded twice. The example of multiplying 3/10 by 7/10 is used, resulting in a product of 21/100. The lesson emphasizes understanding the concept of area in relation to decimal multiplication.
