Find Linear Equations educational ideas and activities
Linear equations, coordinate planes, and systems of equations are covered in this extremely well-organized activity. Composed of a series of mini-lessons, the instruction aims at explaining a different facet of solving systems of linear equations. Each mini-activity inlcudes a printable document, procedure, and objective.
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.
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.
Mathematicians use an inquiry method to solve linear equations. In this linear equations lesson, young scholars 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.
Walk the class through the steps of how to evaluate linear equations and their associated graphs to analyze patterns. Define and discuss key vocabulary terms before having the class observe you model examples of each concept. Then, have individuals independently complete a worksheet.
Sharpen up your algebra class's graphing skills with this helpful lesson. 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 would be a great introduction to linear equations, or as remediation for struggling learners.
For 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.
Illuminate the world of mathematics for your class - specifically, the process of linear equations. In this video, Sal teaches about linear equations in standard form after two videos on slope-intercept and slope-point forms. He defines standard form as "essentially putting all of the x and y terms onto the left-hand side of the equation," and goes on to demonstrate in a few examples.
In an out-of-this-world lesson, space scientists solve systems of equations using graphing, elimination, and substitution. Robots drag strings behind them to create two lines on a grid. Applying math concepts, they write the linear equations for the lines drawn and estimate the points of intersection. You will definitely not alienate anyone with this fabulous lesson! (Note: If you do not have robots, you can plan different ways to create the lines on the coordinate plane.)
Seventh graders explore battle plans using grids. In this linear equation lesson, 7th graders see how math is used in battle. Students create a grid on the floor using tape and plastic army men to serve as the points. Students discuss different scenarios of a battle. Homework will be given for practice.
If you have two bags with an unknown number of tiles, represented by x, and you add three tiles to get seven total, you can set up a linear equation to represent the problem. Use this example and a few others to demonstrate how to solve such problems and fulfill a Common Core standard at the same time. Consider using a couple of bags, some tiles, and a balance to make the concepts more visual for first-time linear equation learners!
Use tables, graphs, and substitution to solve systems of linear equations. An envelope of sample problems is passed around the classroom, and each learner has the opportunity to solve the system in the envelope. This is a great way to get the whole class involved and on their toes. It also allows classmates to hear each other's thinking and problem solving strategies.
Students study the standard form of linear equations and translate equations into different forms. In this linear equation forms instructional activity, 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.
Students explore the concept of linear equations. In this linear equations lesson plan, 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.
