#### Point of Intersection Worksheet 2

Math wizards rewrite pairs of linear equations in the y-intercept form and graph them on a coordinate plane. They identify where the lines cross, i.e. the point of intersection. There are four questions with coordinate planes for drawing...

Lesson Planet

#### Systems on a Mission

Solve systems of equation problems using four different methods: elimination by addition or subtraction, graphing, elimination by multiplication, and substitution. Middle schoolers are then given a series of "missions" to complete.

Lesson Planet

#### Systems of Equations

This is a large unit on the study of the systems of linear equations, solving and graphing. Understanding solutions graphically, and algebraically, learners solve equations by graphing, substitution, and elimination. Real-world problems...

Lesson Planet

#### Solving Systems with Row Operations 2

Have your class solve equations using matrices by teaching them how to factor systems of equation to identify the point of intersection. They create their matrices on the Ti and perform row operations to simplify.

Lesson Planet

#### Solving Systems with Row Operations 1

Students solve systems of equations. In this algebra lesson, students use matrices to solve linear equations. They use reduced row echelon-form and scalar multiplier to simplify the matrices completely.

Lesson Planet

#### Solving Systems using Elimination

Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

Lesson Planet

#### Linear Systems and Calories

Students define and graph properties of linear equations. In this algebra lesson, students write systems of equations to represent functions. They relate linear equations to the real world.

Lesson Planet

#### Solving Systems by Graphing

Solve systems of equations with your super smart upper graders. They solve systems of equations and then graph two lines to find where they intersect. The focus on the activity is to have learners explore moving a point to illustrate...

Lesson Planet

#### Solving a Pair of Linear Equations by Graphing

Teach your math lovers how to solve linear equations by graphing. Students identify pairs of coordinates and use it to graph a line and use the TI to graph and observe the line.

Lesson Planet

#### How Many Solutions 2

Students solve systems of equations. In this algebra lesson, students graph lines and identify the point of intersection. They identify the function to see if it is a function.

Lesson Planet

#### Balanced Systems of Equations

Learners solve equations. In this algebra lesson plan, students relate solving equations to a balanced scale. They add, subtract, multiply and divide on both sides to keep the scale balanced.

Lesson Planet

#### How Many Solutions to the System?

Solve systems of equation using graphing! In this algebra lesson, high schoolers use the TI to graph two lines and identify the number of solutions. They perform interactive graphing on the navigator.

Lesson Planet

#### FCAT Real World Solving Linear Equations/Systems

Pupils relate real life situation to the equations, graphs and inequalities. They model real life scenarios using matrices and draw conclusions from their data. This lesson plan is aligned with FCAT.

Lesson Planet

#### Cramer's Rule ID: 8793

Mathematicians are introduced to Cramer’s Rule and use it to solve three systems that have one solution, no solutions, and an infinite number of solutions. Students use TI-Nspire to graph the systems to verify their answers and...

Lesson Planet

#### Graphing Systems at the Races

Learners investigate systems of equations as they use the Ti-Navigator to explore scenarios about dog races and NASCAR races. Pupils determine the winner of the race and when opponents pass each other given a speed and distance.

Lesson Planet

#### Making Predictions Using Systems of Equations

Students explore the concept of systems of equations. In this system of equations lesson, students enter data into lists on their calculators about 100 meter dash times. Students plot the points using a scatter plot and perform a linear...
