Title: Rewriting Equations and Formulas

Grade Level: 9th-10th grade

Objective: - Students will understand the concept of rewriting equations and formulas. - Students will be able to manipulate equations and formulas to solve for different variables. - Students will apply their knowledge of rewriting equations and formulas to solve real-world problems.

Materials: - Whiteboard or blackboard - Markers or chalk - Handouts with practice problems - Calculators (optional)


  1. Introduction (5 minutes)
    • Begin the lesson by asking students if they have ever encountered equations or formulas in their math classes.
    • Discuss the importance of equations and formulas in various fields, such as physics, chemistry, and engineering.
    • Explain that rewriting equations and formulas is a crucial skill that allows us to solve for different variables and manipulate mathematical expressions.
  2. Review of Basic Algebraic Manipulations (10 minutes)
    • Remind students of basic algebraic manipulations, such as adding, subtracting, multiplying, and dividing both sides of an equation by the same value.
    • Provide a few examples on the board and solve them together as a class.
  3. Rewriting Equations (15 minutes)
    • Introduce the concept of rewriting equations by explaining that we can rearrange the terms and variables in an equation to solve for a different variable.
    • Demonstrate the process of rewriting equations using simple examples, such as solving for x in the equation 2x + 5 = 15.
    • Guide students through the steps of isolating the variable on one side of the equation and solving for it.
  4. Rewriting Formulas (15 minutes)
    • Explain that formulas are equations that express relationships between different variables.
    • Provide examples of common formulas, such as the area of a rectangle (A = length × width) or the Pythagorean theorem (a² + b² = c²).
    • Show students how to rewrite these formulas to solve for different variables. For example, solving for the width in the area formula A = length × width.
  5. Guided Practice (15 minutes)
    • Distribute handouts with practice problems involving rewriting equations and formulas.
    • Instruct students to work individually or in pairs to solve the problems.
    • Circulate the classroom to provide assistance and answer any questions.
  6. Real-World Application (10 minutes)
    • Engage students by discussing real-world scenarios where rewriting equations and formulas are necessary.
    • Provide examples, such as calculating the speed of a moving object using the formula speed = distance/time.
    • Encourage students to think of other situations where rewriting equations and formulas are applicable.
  7. Independent Practice (10 minutes)
    • Assign additional practice problems for students to complete independently.
    • Collect the assignments for assessment purposes or review them in the next class.
  8. Conclusion (5 minutes)
    • Recap the main concepts covered in the lesson, emphasizing the importance of rewriting equations and formulas.
    • Address any remaining questions or concerns from students.
    • Encourage students to practice rewriting equations and formulas regularly to reinforce their understanding.

Note: The duration of each section can be adjusted based on the pace and needs of the students.
