New! Using Linear Equations to Define Geometric Solids
Making the transition from two-dimensional shapes to three-dimensional solids can be difficult for many geometry students. This comprehensive lesson starts with writing and graphing linear equations to define a bounded region and calculating the areas and perimeters of the space. Using this as a base, the lesson then has learners revolve these regions to create solid figures and calculate the resulting volume. A real-world example using a bowling ball and visualization software caps off this in-depth instruction.
Topic 4: Solving Systems of Linear Equations
Linear equations, coordinate planes, and systems of equations are covered in this extremely well-organized lesson. Composed of a series of mini-lessons, the instruction aims at explaining a different facet of solving systems of linear equations. Each mini-lesson inlcudes a printable document, procedure, and objective.
Writing Linear Equations in Different Forms
Can your class write linear equations three different ways? Here is a study guide that includes slope-intercept, standard, and point-slope forms. Learners are given the slope and a point on the line, or two points and are asked to write linear equations in all three forms. Horizontal and vertical lines are also included.
Roman Bernardo: Solving Linear Equations
Mathematicians use an inquiry method to solve linear equations. For this linear equations lesson, students practice solving equations using addition, subtraction, multiplication and division. They solve multi-step equations and equations with variables on both sides of the equal sign. Each section features a class discussion, and work sample questions. The final activity requires students to work in small groups to plan a one-day trip to France.
Graphing Linear Equations and Functions
Here is a complete chapter on graphing linear equations and functions. Learners review graphing points on a coordinate plane, graph lines and functions, and write linear equations.
Writing and Graphing Linear Equations on a Flat Surface
In this linear equations worksheet, students write the equation of a line with given characteristics. They identify the slope of a line and the y-intercept. Explanations and examples are provided at the beginning of the worksheet. This six-page worksheet contains 57 problems. Answers are provided on page six.
Algebra: Linear Equations 4
This is a lesson in solving linear equations. More specifically, students will see how to solve an equation with a variable expression in the denominator of a fraction.
Graphs of Linear Equations
Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to word problems that are more complicated.
Linear Equations Game
Students participate in a mathematics game in order to investigate the concept of linear equations. They practice using rotations of the game to solve the equations. The teacher can intervene as necessary.
Graph Dynamic Linear Equations
Students explore the concept of linear equations. For this linear equation lesson, students change parameters of an equation and notice the effect it has on its graph.
Plotting (x, y) Relationships
Delve into the relationship between x and y as it relates to graphing linear equations. Sal simplifies a trinomial expression, creates a function table, and then plots the coordinates on a graph. Because the relationship between the graph, coordinates, and equation is clearly described in this video, it would be great for extra support or independent study.
Solving Linear Equations
Ninth graders solve linear equations. In this algebra lesson, 9th graders discuss the steps for solving linear equations and work through examples with the teacher. They work in pairs to create their own linear equation and complete a worksheet on the same topic.
Students solve linear equations using the slope and y-intercept. In this algebra lesson plan, students use linear equations to solve real life problems.
Detective Work in Linear Equation Forms
Students study the standard form of linear equations and translate equations into different forms. In this linear equation forms lesson, students graph relevant information using slope intercepts. Students use clues and solve for missing information. Students then rewrite equations into different forms. Students complete a written partner test.
Graphing Linear Equations
Ninth graders develop an understanding of and the applications for linear equations and their graphical displays. They participate in a cooperative learning activity of matching a graphic display with an equation.
Exploring Linear Equations
Students explore the concept of linear equations. In this linear equations lesson, students enter life expectancy data into their graphing calculator and plot the data. Students make a scatter plot of the data and determine a linear equation to represent the data. Students predict the life expectancies of a person born in a particular year.
The Pattern of Graphing Linear Equations
Sharpen up your algebra class's graphing skills with this helpful lesson plan. Working as a class, math learners practice graphing linear equations from geometric representations. After working with a document camera and completing online research, they continue to work independently to master the skill of graphing. This lesson plan would be a great introduction to linear equations, or as remediation for struggling learners.
Supply and Demand - An Application of Linear Equations
Students create and solve a system of linear equations in a real-world setting. By solving the system, students will find the equilibrium point for supply and demand. Students should be familiar with finding linear equations from two points.
Point Slope Form of a Linear Equation
Students solve linear equations using the point slope formula. In this algebra lesson, students solve the equation of a line without the y-intercept or the slope using the formula.
In this algebra activity, students solve linear equations through graphing and the use of formulas. There are 34 questions ranging from addition and subtraction of linear equations to graphing and substitution.
