New! Isolating the Variable
Ninth graders investigate how to solve equations with the variable present on both sides. They practice isolating the variable and combining like terms before solving the equation for the variable.
Solving One Step Equation
Students solve one step equations. In this algebra activity, students solve linear equations using division, multiplication, subtraction and addition. They investigate the correct way to keep an equation balanced.
Systems of Linear Equations
Middle and high schoolers solve systems of equations relating to money and explore substitution and elimination strategies. In this activity, pupils review The Chicken and Pigs problem and compare their solutions with the graphing solution. They complete the worksheet on systems of equation for practice.
A Balancing Act: Solving Multi-Step Equations
Wow! Put on that thinking cap and solve multi-step equations. To solve equations, learners review the use of the distributive property and combining like terms. This three-day lesson comes with about 20 pages of worksheets, warm-ups, quizzes and answer keys.
Difference of Equations
For this difference of equations worksheet, students solve and complete 49 various types of problems. First, they obtain the solution of any linear homogeneous second order difference equation. Then, students apply the method of solution to contextual problems. In addition, they use generating functions to solve non-homogeneous equations.
Solving Systems of Equations by Graphing
In this systems of equations worksheet, students solve systems of equations by graphing. They identify the intercept of two lines. This two-page worksheet contains 12 multi-step problems. Explanations and examples are provided.
Solving Systems of Equations by Elimination
Elimination is another way to solve systems of equations besides graphing and substitution. Sal's lecture is clear and easy to understand even for struggling learners. By having a variety of options when faced with linear equations, one can truly dissect a problem and use the method that is most beneficial for him.
Linear Equations in Standard Form
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.
One Step Equations
Stating that "the fun thing about algebra is that you can always check your answer," Sal demonstrates the simplest ways to solve several algebraic equations. He specifies that viewers should focus on the steps he's taking and why he's choosing that process.
Systems of Equations: What Method Do You Prefer?
Learners explore the concept of solving systems of equations. In this solving systems of equations lesson, students watch YouTube videos about how to solve systems by graphing and by elimination. Learners use an interactive website to solve systems by substitution.
