Agenda:

1. Review on "Equations and Expressions"

2. Complete Missing Quizzes

3. Complete Missing Work

REVIEW:

-Parts of an Algebraic Expressions
- Solutions of an Equation
- Solving Equations

SWBAT:
1. Understand that solving an equation means finding a value of the variable that makes the equation true. 
2. Use substitution to show whether a number in a specified set is a solution of an equation.
3. Solve one-step equations by using algebraic reasoning.

​Objectives:

6.EE.B.7
Solve real-world and mathematical problems by writing and solving one- step equations of the form x + p = q, px = q, x – p = q, and x/p = q for cases in which p, q, and x are all nonnegative rational numbers and p ≠ 0. (Complex fractions are not an expectation at this grade level.)

Standard:

​Solution of an Equation

- a value that can be substituted for a variable to make an equation TRUE.
