QUESTION # 1 If =, this is an example of the ______ Property. QUESTION # 2 Mr. Pearson DO NOW Tuesday, September 3, 2013 Selby Lane is an example of the ______ Property.

Objective - To use the distributive property to simplify numerical and variable expressions. Distributive Property or Order of Operations Distributive Property It works! Why use the distributive property? CA Standard: 7 th Grade Algebra & Functions 1.3 Simplify Numerical Operations by Applying Properties (Associative, Commutative, Distributive, Identity, etc.) of Rational Numbers and justify the process.

Simplify using the distributive property. 1) 2) 3) 4) 5) 6)

Use the distributive property to write an equivalent expression. Then simplify both to show they have the same value. 1) 2) 3) same

Geometric Model for Distributive Property Two ways to find the area of the rectangle. 4 52 As a wholeAs two parts

Geometric Model for Distributive Property Two ways to find the area of the rectangle. 4 52 As a wholeAs two parts same

Find the area of the rectangle in terms of x, y and z in two different ways. x yz As a wholeAs two parts

Find the area of the rectangle in terms of x, y and z in two different ways. x yz As a wholeAs two parts same

This means that you can multiply 1 to any number... and it keeps its identity! The number stays the same! Let's look at the number 8. Anyway we try to multiply 1 to it, the 8 just keeps coming back as the answer. This means that you can add 0 to any number... and it keeps its identity! The number stays the same! Let's look at the number 5. Anyway we try to add 0 to it, the 5 just keeps coming back as the answer.
