In this engaging 7th grade math activity, students analyze graphs of proportional relationships in real-world scenarios such as lemonade stands, taxi fares, music downloads, and printing costs. Using clearly labeled interactive graphs, students determine what each point means and identify the unit rate—with special attention to the points (0, 0) and (1, r), where r is the unit rate.
Students:
Students will analyze and interpret proportional relationships represented on graphs. They will identify the meaning of key points—including (0, 0) and (1, r)—in real-world contexts, and determine the unit rate by examining patterns in the data. Through multiple scenarios, students will develop a deeper understanding of how proportional relationships are visualized and explained using coordinate graphs.
If randomization is enabled, each student will receive different unit rates in each graph. This means that the slopes of the lines and total values at each point will differ.
💡 Tip: When assigning this activity to your classroom, you can optionally enable randomization to give each student a unique version of the problems. When you re-assign the same worksheet, each student will get a new set of questions, helping them master the content through repeated practice.
