Do Now

Start the class session by presenting students with a real-world problem scenario. For this exercise, you can provide a problem related to shopping, such as this one:

"If a bottle of shampoo that costs $5 can last for 15 days. What is the amount spent on the shampoo for a year if you buy it every month?"

Ask students to take a few minutes to think about a way to approach the problem and come up with a possible solution.

Practice

After discussing the do now problem, move on to the practice exercises. Provide a few real-world problems that involve proportional reasoning, and explain the key concepts and formulas involved in solving them.

Here are some sample problems that you can use:

1. "If it takes 3 hours for 5 painters to paint a house, how many hours will it take for 7 painters to paint the same house?"
2. "If a brick wall of 20 feet requires 12 bricks to build, how many bricks are required to build a wall of 50 feet?"
3. "A recipe for cupcakes requires 3 cups of flour for 12 cupcakes. How many cups of flour are required to make 45 cupcakes?"

Once you have presented the problems, walk students through the step-by-step process of solving them, using proportional reasoning. Encourage students to work in pairs or small groups to solve the problems.

Exit Ticket

As a way to wrap up the lesson, provide students with an exit ticket that allows them to demonstrate their understanding of the concept. Here's an example of an exit ticket question:

"Suppose a car goes 80 miles per hour. How many miles would the car travel in 5 hours?"

Ask students to write their answer on a piece of paper, and then collect the papers as they leave the classroom. You can grade the exit tickets and provide individual feedback to each student.

Conclusion

In conclusion, this lesson on proportional reasoning is designed to help students solve real-world problems related to shopping, painting, and cooking. By providing do now exercises, practice problems, and an exit ticket, students will have ample opportunity to explore and master the underlying concepts.
