#### Solving Systems of Linear Equations by Graphing - Part 1

Determine a solution through accurate graphs. Using 2 examples, the narrator walks viewers through the steps to graph a system of linear equations to find the solution.

Lesson Planet: Curated OER

#### Solving Systems of Equations Graphically

Confirm the types of solutions by graphing. The video begins with a discussion on the number of solutions and the types of systems by looking at their graphs. Using several examples, the narrator shows the class how to find the solution...

Lesson Planet: Curated OER

#### Solving Systems of Linear Equations by Graphing - Part 2

Not all systems have a single solution. To begin the video, the narrator reviews the different number of solutions possible with a system of linear equations. He continues with examples of solving systems of equations by graphing. Unlike...

Lesson Planet: Curated OER

#### Stacking Cups

What do disposable cups and engineering design have in common? That's up to your pupils to discover! Using tables and equations, learners model the pattern of the height of a stack of cups compared to the number of cups. They use what...

Lesson Planet: Curated OER

#### Solving Simultaneous Equations Graphically

The solution resides at the intersection. Pupils use a short instructional activity to review the process of solving a system of linear equations using graphing. The instructional activity provides completed graphs for most of the items,...

Lesson Planet: Curated OER

#### Smarter Balanced Sample Items: High School Math – Claim 2

Problem solve across the content standards. The presentation slides provide 19 sample items from the Smarter Balanced high school assessment. Items illustrate Claim 2, problem solving, of the test and are drawn from all the high school...

Lesson Planet: Curated OER

#### Systematic Solution I

Writing a general rule to model a specific pattern is a high-level skill. Your classes practice the important skill as they write rules describing the solutions to a system of equations with variable coefficients. As an added challenge,...

Lesson Planet: Curated OER

#### Three Circles

Round and round and round we go. Given a diagram of three circles, two of which share a point with the third circle, learners identify the radius of each circle. Doing so requires setting up and solving a system of equations based on the...

Lesson Planet: Curated OER

#### Go with the Flow

Round and round they go ... where they stop, only scholars will know. By writing systems of equations, classes determine the number of cars a roundabout can handle given specific constraints. Systems use up to six variables and become...

Lesson Planet: Curated OER

#### Module 5: Systems of Equations and Inequalities

Systems of equations and inequalities model contextual situations. A set of 12 lessons build a solid understanding of writing and solving systems of equations and inequalities using a variety of methods. The module is the fifth in a...

Lesson Planet: Curated OER

#### Sandwich Shop

Eat up the task on systems of equations. Given information on the total number of sandwiches and the total income, learners write and solve a linear system of equations to find the number of each type of sandwich sold at a shop. They...

Lesson Planet: Curated OER

#### A Linear System

Young mathematicians have the hang of graphing with integer coefficients now. Can they generalize what they've learned to equations with variable coefficients? The task asks individuals to verify the solution to the system is (x,y) and...

Lesson Planet: Curated OER

#### Betweenness I

Just between us, this is a pretty cool lesson! Given two functions with the same slope, learners write three new functions whose outputs are all between the given functions. The question is open-ended, allowing pupils to explore the...

Lesson Planet: Curated OER

#### Writing Expressions to Solve a Linear Equation App: Coins

Your classes will be cashing in on this lesson! A well-designed lesson describes the steps of solving for the number of two different coin types given specific information. Although some may write equations using two variables, the...
