Original Prompt

Use variables to represent two quantities in a proportional relationship in a real-world problem; write an equation to express one quantity, the dependent variable, in terms of the other quantity, the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. (E)

This learning resource is focused on teaching students about proportional relationships in various real-world contexts. It covers the identification of independent and dependent variables, and introduces the concept of the constant of proportionality. Students will engage in hands-on activities such as creating tables, plotting graphs, and writing equations of the form y = kx. The resource includes worked examples using scenarios like the cost of apples per pound, car travel distance, baking loaves of bread, and earnings from mowing lawns. Additionally, students will practice identifying variables, creating tables, and writing equations through practice problems. The final section encourages students to reflect on their understanding of the constant of proportionality and how graphical representations enhance their learning.
