Lesson Plan

Exploring Proportions in the Real World

Proportions are hugely important to real-world problem solving. This app flow will show your 7th graders some ways we use proportions to answer questions in real life.

1 Hook

Before you start the lesson, give students a pre-quiz to find out what they already know about proportions. You could include questions about equivalent ratios, unit rates, and ratio language to activate their prior knowledge, which will put them in a great mindset for these activities.

2 Direct Instruction

From $220

The introduction to proportions video on BrainPop shows an excellent real-world example of problem solving using proportions. Show students the video, then walk them through several more examples of how to solve proportion problems.

3 Guided Practice


The free lesson "On Your Mark" from Mathalicious asks a compelling question: Do taller runners have an advantage in Olympic track races? What if runners had to complete a distance proportional to their height, instead of all runners covering the same distance? Your students will get lots of experience practicing writing and solving proportions in this lesson.

4 Independent Practice

Free to Try, Paid

To cement and generalize their knowledge of solving proportions, students can practice on IXL.com. This website has several options for proportion problems, including story problems. Your students will receive instant feedback on their answers, and can monitor their progress with their SmartScore. Best of all, the teacher can easily see who has mastered the content and who needs more support.

5 Wrap-Up

Kahoot! is an awesome way to wrap up any math unit. Include a variety of question types and answer options for a rich, summative assessment that's way more fun than a paper-and-pencil quiz! Students will love the quick game format, and the teacher can use the data collected by the game for future planning.
