This lesson covers two different methods for determining equivalent ratios using scaling up and scaling down in order to utilize ratio tables and double number lines.
The PowerPoint is designed to be used to introduce the topic or at the end of a unit to summarize the concepts. Ideally, the teacher can display the presentation for the students and they can take notes, have a class discussion, or both. Slides can be printed for students to put into interactive notebooks as well, and the last slide is included expressly for printing and providing to students.
Additionally, this file can be uploaded to Google Classroom as a Google Slides document and viewed on "Present" mode if you would like students to use this individually or even at home for front-loading or summarizing a lesson.
The 8 slides are designed to present the information a bit at a time. They are not 8 unique slides, but rather use animation to add information a piece at a time so that teachers can present the information without overwhelming the students with too much, too quickly.
Designed to align well with Carnegie Learning Middle School Math Solution: Course 1 - Module 2, Topic 1, Lesson 4.
