Using Formulas, Distributive Property
Distributive Property is a key Grade 7 math skill in Saxon Math, Course 2. The Distributive Property lets you multiply a sum by 'spreading' the multiplication over the terms being added or subtracted within parentheses. The Distributive Property is often Think of the Distributive Property like handing out party favors.
Key Concepts
New Concept The Distributive Property lets you multiply a sum by 'spreading' the multiplication over the terms being added or subtracted within parentheses.
The Distributive Property is often expressed in equation form using variables: $$a(b + c) = ab + ac$$ The Distributive Property also applies over subtraction: $$a(b c) = ab ac$$ What’s next Next, you'll see worked examples that use the Distributive Property to simplify expressions and connect two different formulas for a rectangle's perimeter.
Common Questions
What is Distributive Property in Grade 7 math?
The Distributive Property lets you multiply a sum by 'spreading' the multiplication over the terms being added or subtracted within parentheses.
How do you solve Distributive Property problems?
rule looks like this: `a(b + c) = ab + ac` - It works for subtraction too: `a(b - c) = ab - ac` Test-style question: Use the distributive property to write an equivalent expression for `5(2x - 3)`.
What is a common mistake when learning Distributive Property?
Common mistake tip: The most common mistake is only multiplying the outside number by the *first* term.
Why is Distributive Property important for 7th graders?
use the Distributive Property to simplify expressions and connect two different formulas for a rectangle's perimeter.
Can you show an example of a Distributive Property problem?
Use the distributive property to write an equivalent expression for `5(2x - 3)`. Solution: - Step 1: Identify the number outside the parentheses (`5`) and the two terms inside (`2x` and `-3`).
What grade level covers Distributive Property?
Distributive Property is taught in Grade 7 as part of Saxon Math, Course 2. It builds procedural fluency and prepares students for pre-algebra and geometry.
