Lesson Excerpt:

I. Introduction

- "Today we are going to begin working on ratios. When we talk about ratios, we are talking about comparing. We can compare objects, shapes, numbers, money, lots of different things can be compared. When working with ratios, know that we will be comparing different things."
- Note: You may want to change this example to match with something in the classroom. That will make it a real life example for the students.
- "Let's start this lesson by comparing two things. Let's compare the number of windows in this room to the number of blackboards. There are six windows in this room and two blackboards. Now, if I am comparing windows to blackboards, then the number of windows will come first when I am writing the ratio."
