Create a worksheet for 7th grade math class to teach them about constant of proportionality

The resource explores the concept of the Constant of Proportionality, which is the specific ratio that indicates a proportional relationship between two quantities. It introduces the formula to find this constant (k = y / x) and explains how it can be represented in equations (y = kx). Key identification rules are provided, including the characteristics of proportional relationships on graphs, which must form straight lines and pass through the origin. The document includes examples and practice problems related to real-world scenarios, such as rates of pay and recipe scaling, helping learners to identify and calculate the constant of proportionality. It also emphasizes understanding its meaning in various contexts, reinforcing the connection between the constant and unit rates in real-life applications.
