By the end of the lesson, students will be able to:
As students enter the room, they should be given a worksheet with several problems related to proportional reasoning. Provide them with 5 to 10 minutes to complete the problems.
Begin the lesson by discussing what proportional reasoning means. Explain that it is the process of determining whether two or more quantities are related in a particular way, and if so, how they are related.
Next, describe the concept of unit rate. Explain that it is the rate of change of one quantity with respect to another, expressed as a ratio in which the second quantity is one unit. Give examples of unit rates using measurements such as distance, speed, and time.
After reviewing unit rates, introduce the concept of scaling factors. Explain that a scaling factor is a number that multiplies or divides another number to change its size. Provide examples of how to use scaling factors to convert measurements from one unit to another.
Finally, discuss inverse proportionality. Explain that two quantities are inversely proportional if their product is a constant. Provide examples of how to solve inverse proportionality problems.
Provide students with a worksheet that includes multiple problems related to unit rate, scaling factors, and inverse proportionality. Give students 15 to 20 minutes to work on the problems independently. Encourage them to use the techniques and concepts reviewed in the mini-lesson.
Before the end of the class, ask students to complete an exit ticket that includes several problems related to proportional reasoning. The problems should be similar to the ones given in the do now and practice sections of the lesson. Collect the exit tickets and use them to assess student understanding of the lesson.
In conclusion, this lesson teaches students how to solve problems using proportional reasoning, including unit rate, scaling factors, and inverse proportionality. The lesson plan includes a do now, mini-lesson, practice, and an exit ticket to help students solidify their understanding of the concepts. By the end of the lesson, students should be able to demonstrate competency in solving problems using proportional reasoning.
