Unit 8: Solving Simultaneous Linear Equations

Lesson 2 of 15

Lesson 2 of 15

## Objective: SWBAT develop a system of equations to solve a hands on problem solving based activity.

## Big Idea: Introduce systems of equations with a lab that keeps them guessing and engaged with a real world challenge.

Subject(s):

Math, Systems of Equations and Inequalities, Algebra, Linear and Nonlinear Equations, 8th grade, linear equations in two variables, linear equations (graphs), Real world problems, problem solving, hands on learning, master teacher

#### Bellringer - Warm up

*5 min*

The activity today will take most of the class period to complete so I would keep the bellringer work short but important. I would ask students a simple question such as graph the equation y = 2x - 6. Move about the room assessing students and select one student to present under the document camera. After the presentation, ask students how many solutions the equation y = 2x - 6 has and discuss fully why infinite solutions is a logical answer. Let students know that the new unit is also centered around linear equations in two variables but these equations sometimes have only one solution to fit the situation. The lab today is an introduction to the unit.
