Math Solving Equations by Multiplying or Dividing 8th Grade
 * Subject **
 * Topic **
 * Grade Level **

Focus attention/motivation: 5 minutes Instructional input and modeling: 15 minutes Student engagement/practice: 20 minutes Closure: 5 minutes
 * Time Frame **

The overall goal of this lesson is for the students to solve equations using multiplication and division.
 * Overall Goal/ Purpose **

IL.8.A.3b Solve problems using linear expressions, equations and inequalities. IL.8.D.3a Solve problems using numeric, graphic or symbolic representations of variables, expressions, equations and inequalities. The students will be able to solve equations using multiplication and division.
 * State Standards **
 * Instructional Objectives **

· copies of puzzle · smart board · copies of practice game · glue · construction paper
 * Materials **

Focus Attention/Motivation: · I will have some students share their math poems they wrote for homework to review the vocab from the day before. · I will show the students an egg carton for a dozen eggs. · I will tell them: -“I spent $1.20 for this carton of eggs. I wonder how much one egg cost.” · I will then write on the board: 12c = 1.20 · I will tell them: -“If I solve this equation to find the value of C, I will now the cost of one egg.” · I will then ask the students how they think I should go about finding the value of C. · I will write their suggestions on the smart board.
 * Procedures **

Instructional Input & Modeling: · I will explain to the students that the main point of this lesson is very similar to what we learned the day before. · I will point out that multiplication and division are also inverse operations, so one “undoes” the other. · I will put a few examples on the over head along with the egg example and solve them to the students using a “think aloud” method. -7X = 35 · I will inform students that to solve two-step equations that the students need to undo the addition and subtraction first. -It is in a reverse order of the steps.

Student Engagement/Practice: · The students will then partner up and complete a practice guide completing the equations from the exploration book. · The students will then take turns going up to the smart board and writing the problem and how they got the problem on the board. · Explaining HOW and WHY that is the answer. -It is important for the students to understand the how and why of the equation. · The students will then receive a puzzle equation sheet (attached). · The students have to solve the equations on each puzzle piece, which are addition, subtraction, multiplication, and division. · They cut out the puzzle pieces and then match them with the correct solution and paste them onto a piece of construction paper. · Students can work with their shoulder partner if necessary.

Closure: · I will ask students to explain each of the four properties of equality. · I will show the class some one-step equations and ask them to identify which property should be used to solve each equation. · I will then show them some 2 step equations and ask them which property they should apply first.

The students will be assessed from the beginning of the class when I have them brainstorming how we could solve the equation. I will use a formative assessment when the students work in groups and take turns going to the board to show the class the answer and how they got to that answer. I will use their finished puzzle as their summative assessment because in order to complete the puzzle they have to correctly solve the equations.
 * Assessment **

I will have the __struggling students__ meet with me in the back of the classroom. We would work on easier problems and I would show the students using a manipulative.
 * Accommodations **

I will give the __gifted students__ copies of newspaper ads. I will have them find examples of prices, such as 88 cents or 6 for $1.50 for each example the students will write and solve an equation to find the cost of a single item.
