Lesson Plan: Direct Variations

In this lesson, students will explore direct variation, a special type of proportional relationship where one variable is a constant multiple of another. They will learn how to identify direct variation in tables, graphs, and equations, determine the constant of variation ($k$), and understand how direct variation relates to linear functions.

Key concepts covered in this lesson include:

• Understanding direct variation and its equation $y = kx$.
• Identifying direct variation in tables by checking for a constant ratio.
• Graphing direct variation and recognizing that all such graphs pass through the origin.
• Determining the constant of variation ($k$) from equations, tables, and graphs.
• Applying direct variation to real-world scenarios, such as speed-time and wage-hour relationships.

Through guided practice and problem-solving activities, students will strengthen their algebraic reasoning and develop a deeper understanding of proportional relationships. This lesson provides a strong foundation for exploring linear equations and functional relationships in future math concepts.
