Let’s Review Vocabulary: linear expression, rational coefficient, combine like termsĤ Properties of the Real Numbers: Commutative: 11 + 4 = 4 + 11Īssociative: (4 + 3) + 9 = 4 + (3 + 9) Distributive: 5(6 + 2) = 5(6) + 5(2) Let’s Review Review the commutative, associative, and distributive properties of the real number system.ĥ Failing to distribute negative numbers completely:
Presentation on theme: "Hook How do you expand linear expressions that involve multiplication, addition, and subtraction? For example, how do you expand 3(4 + 2x)? Coach’s Commentary."- Presentation transcript:ġ Hook How do you expand linear expressions that involve multiplication, addition, and subtraction? For example, how do you expand 3(4 + 2x)? Coach’s Commentary I chose this example because it is easy to demonstrate with an area model, which gives students a concrete way to visualize the distributive property of multiplication over addition.Ģ Objective In this lesson you will learn how to expand linear expressions with rational coefficients by using the properties of real numbers.ģ Vocabulary: Linear expression Rational coefficient Combine like terms
