Important Note: The PowerPoint animations in this lesson don't work with Google Slides. You must use PowerPoint!
Ratios and proportions are a rockin in this lesson. Students will start off the lesson watching a PowerPoint presentation to help them get a grasp on the vocabulary pertaining to the upcoming problems. While watching, students will copy down the definitions and examples into their packet! Students then will progress from simple proportions to more complicated ones. They will learn two methods for solving proportions as well. First they will watch the power points showing them how to solve a proportions like any other equation, i.e. using inverse operations. (This is my preferred method.) They will also be shown how to check their solutions. They will then watch the power points showing them how to cross-multiply to solve a proportion. Again, while watching they will copy down the steps into their packet. Then students will collect data and use proportions to figure out the most popular summer sport in the school. After this activity students will continue to watch the power point showing them how to solve two real world problems involving gross a pay and commissions. They will then work together on more real world problems!
Nifty Note: The integration of the step by step power points has really helped me in this lesson, because I don’t have to spend all my time explaining concepts on the white board. Instead I have students watch the power point and if they get stuck on a step I simply stop the presentation and explain what is going on. Furthermore, the students have space in their packets to write down the steps as we go! I have received incredibly positive responses from my students. They say that the animations of the power point make it so much easier to understand and they want me to teach all of my lesson this way for now on! I They also say that learning math this way is just more fun in general. I hope you have this success with your students when using this product as well!
Note, for students who are absent, I simply transfer the PowerPoint presentation onto a computer and have them watch it individually!

Page 2: (Partner, Group, or Independent Practice)
Students will work with a partner, group, or independently on exercises #1–6. (15 minutes)
Show slide 5 of the PowerPoint so students can check their answers to these six exercises. Have class discussions as needed. (10 minutes)
Page 3: (Whole Class) Problems A and B
The whole class will watch slides 6 and 7 of the PowerPoint. These slides show students how to do these problems. They will copy down the information into their packet. (15 minutes)
Page 4: (Partner, Group, or Independent Practice)
Students will work with a partner, group, or independently on exercises #7–10. (15 minutes)
Show slide 8 of the PowerPoint so students can check their answers to these four exercises. Have class discussions as needed. (10 minutes)
Page 5 and 6: (Whole Class Activity)
Please refer to the packet and PowerPoint (slides 9 through 12) for guidance on this activity. Note: The data for this will be different for each school and as a result, answers for all bulleted items will vary. (40 minutes)
Page 7 (Whole Class) Problems C and D
The whole class will watch slides 13 and 14 of the PowerPoint. This presentation shows students how to do these problems. They will copy down the information into their packet.
Page 8: (Partner, Group, or Independent Practice)
Students will work with a partner, group, or independently on exercises #12–14. (25 minutes)
Show slides 15 of the PowerPoint so students can check their answers to these five exercises. Have class discussions as needed. (15 minutes)
Note: The zipped file contains the 2- page “instructions for use please read” file, the 8-page lesson, the 8-page key, and 15 animated slides. The instructions, lesson, and key are PDF files. The slides are done in PowerPoint.
