__Topic/ Title__: Solving multiple - steps equations

__Description__: Students will solve multi - steps equations by modeling the equation.


 * __Objectives__****:** **Understand how to solve multi -step equations by doing the same operation on the both sides.**
 * __Duration__****:** **one period block 45min.**


 * __Materials__****:** **smart board, data projector, laptops, notebooks**


 * __Procedure__****:**


 * Do now:** How can we find the solution for multiple step equation?


 * Minilesson:** **Review how to solve the multi - step linear equation. Watch instructional video.**

• Students will create three linear equation • (Make surethat the equations are in the form Ax + B =Cx + D and make sure that A+C is more than 10 and B + D is less than 10) example: 3x + 3= x + 7 • Then share them with a classmates • Solve the equation in your notebook • Model friends equation in the algebra balance scale
 * Activity:**

- Students will present step by step solution - Students will do the check in their notebook
 * Share:**
 * -** Write your own procedure for solving multi-step equation


 * __Differentiation__****:**


 * __Assessment__****: Solve the following equations**
 * a) 5x – 6 = 2x +3**
 * b) 7x -2 = 2x + 13**
 * c) 8x – 4 = 3x + 16**
 * d) 3x - 11 = x – 5**

__Grade Level(s):__ 8th
