The Distributive Property and Area Models
The Distributive Property and Area Models is a Grade 3 math skill from Eureka Math, Grade 3, covering Arithmetic Properties Using Area Models. The distributive property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. This is also known as the 'break apart and distribute' strategy. Explanation This property is visually represented when you decompose a large rectangle into two smaller ones. The total area can be found by calculating the area of each smaller rectangle and then adding them together.
Key Concepts
The distributive property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. This is also known as the 'break apart and distribute' strategy. $$(a + b) \times c = (a \times c) + (b \times c)$$.
