1. Simplifying Expressions and Multi-Step Equations Review We are learning to…simplify expressions and solve equations by isolating a variable. Thursday, August 06, 2015

2. Simplifying Expressions Review  When you are asked to simplify an expression we are looking for you to be able to: Combine like terms…pieces of a mathematical expression which are exactly the same. And then re-write and equivalent expression in “simplest form.”

3. Simplify the expression: 2x + x 2 – 3 + 3x – 3x 2 – 1 Drawing: x x x2x2 x x x x2x2 x2x2 x2x2 1 1 1 1 Create and Remove any Zero Pairs! And then write the write the expression in simplest form. Expression in Simplest Form: 5x – 2x 2 – 4 Practice writing some expressions in simplest form. After you finish each question raise your hand so your teacher can check your solution.

4. Solving Multi-Step Equations Review  When you are asked to solve an equation we are looking for you to be able to: Combine like terms (if necessary) Then find the solution by isolating the variable:  First eliminate any units by adding or subtracting  Then multiply or divide to find the value of one variable.

5. Solve the equation below: = x x 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Record your steps: Check your work: Try practicing solving a few equations with your team!

6. Writing Multi-Step Equations Review  When you are asked to write an equation we are looking for you to be able to: Use the given in the problem situation to create an equation. Then use your equation solving skills to find the solution to the problem situation.

7. Seth’s age is 7, which is 3 more than half of Regina’s age. How old is Regina? Verbal Model: Define the variable(s): x = Regina’s age Regina = Seth+ 3 Mathematical Representation (as an equation): Solve this equation with your teammates…raise your hand when you are done.
