Practice the Distributive Property with Models.
The model below is the distributive property for 2 x (3 + 4). The entire rectangle in the applet below represents 2 x (3 x 4). The shaded region represents 2 x 3, and the unshaded region represents 2 x 4. Always note that the shaded portion will represent the first multiplication of the numbers that you choose, while the unshaded portion will represent the second multiplication.
Match Equivalent Expressions.
Draw lines to match each expression in column 1 to an equivalent expression in column 2. If you get stuck, consider drawing a diagram in the second applet below.
Apply the Distributive Property to write Equivalent Expressions.
In the following activity, you are going to use the distributive property to write equivalent expressions. The instructions on how to interact with the applet are given below.
A rectangle with dimensions 6 cm and W cm is partitioned into two smaller rectangles.
Explain why each of these expressions represents the area, in cm2, of the shaded region.
(1.) 6W – 24
(2.) 6(W – 4)
