Weekly Agenda Monday: MobyMax – (Math) Tuesday: Intro to Vocabulary / Intro to Solving One-Step Equations Wednesday: Distributive Property Quiz Thursday: Practice with Solving One-Step Equations. Friday: - MobyMax – (Fact Fluency)/ Homework is Due

Monday Log in to MobyMax Click on Math Bell-to-bell

Tuesday New Vocabulary Intro to Solving One-Step Equations

TERM – a number, a variable, or a product of numbers and variables ALGEBRAIC EXPRESSION – a mathematical phrase involving at least one variable and sometimes numbers and operation symbols. No = sign! COEFFICIENT – a number multiplied by a variable in an algebraic expression or equation.

Vocabulary VARIABLE – A letter symbol used to represent a number. CONSTANT – a quantity or term that does not change its value. It does not have a variable. EVALUATE – to find the value of an expression by replacing each variable in the expression with numbers. (ie find the answer)

Addition A + 5 5 + A B + 5 = 12 5 + B = 12 Use the Subtraction Rule of Equality

Subtraction H – 7 7 - H H – 7 = 2 7 – H = 2 Use the Addition Rule of Equality

Multiplication 5G G5 (very rarely used) 5G = 30 Use the Division Rule of Equality

Division P/6 6/P P/6 = 3 6/P = 3 Use the Multiplication Rule of Equality

One-step equations Y + 7 = 10 L – 6 = 2 4F = 20 M/5 = 4 24/N = 3 Remember your Rules of Equality

Wednesday Distributive Property Quiz

Warm-up September 13, 2016 Use the Distributive Property to simplify:

Distributive Property Quiz You will need a sheet of nice, clean, not torn notebook paper. CIRCLE your answer and show your work! When you finish the quiz stay in your seat and work silently on page 167, problems 1 – 6 and problem 11 and page 185, problems 1 – 5. Read and look over the examples!!!!!!!!!

Distributive Property 5 ( 6 + M ) -5 ( 6 + M ) 3 ( 5 + T ) 8 ( 4 – Y ) CIRCLE YOUR ANSWERS -8 (4 – B )

Answers 30 + 5M -30 + (-5M) 15 + 3T 32 – 8Y -32 – (-8B) or -32 + 8B
