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)

Procedure:

- 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.

- 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.

- 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.

- 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 Ã— width) or the Pythagorean theorem (aÂ² + bÂ² = cÂ²).
- Show students how to rewrite these formulas to solve for different variables. For example, solving for the width in the area formula A = length Ã— width.

- 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.

- 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.

- 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.

- 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.
