Exploring Area Models and the Distributive Property

The video tutorial teaches how to find the area of rectangles using the distributive property. It begins with an introduction to area and benchmark numbers, followed by an explanation of unit squares and how to calculate area by multiplying rows and units. The lesson then demonstrates decomposing rectangles to find their area, using examples with benchmark numbers. Finally, it calculates the area of posters made by Jalen and Kayden, reinforcing the concept of using the distributive property to find area.

What is the area of a shape defined by unit squares?

What benchmark numbers are mentioned for making estimates?

• 10, 20, 30, 40, 50

• 5, 10, 25, 50, 100

• 1, 2, 3, 4, 5

How do you calculate the area of a rectangle using the distributive property?

• Subtract the smaller dimension from the larger one

• Multiply the total number of rows by the number of units in each row

• Add the length and width

• Divide the rectangle into smaller sections and sum their areas

What is the area of a rectangle that is decomposed into 4 rows by 5 units and 4 rows by 2 units?

• 28 square units

• 32 square units

• 10 square units

• 16 square units
