This is our first lesson from the unit, Proportional Reasoning. Here, we begin with ratios and discuss how to build up a ratio in order to create a proportion.
Let's go over the assignment for lesson 1.
This is our second lesson from the unit, Proportional Reasoning. Here, we begin with ratios and discuss how to build down a ratio in order to create a proportions. We also discus comparing ratios
Let's go over the assignment for lesson 2.
A quick introduction to variables and a discussion about Cross-Product. We'll use what we learned from the previous two lessons and apply multiplication and division to finding missing values to proportions.
Let's go over the assignment for lesson 3.
Let's apply what we've learned to some real-world examples of proportions. They are everywhere!
Let's go over the assignment for lesson 4.
We begin the second section of our first unit by discussing the concept of unit ratios.
Let's go over the assignment for Lesson 5.
In this lesson, we talk about multiplicative comparisons and dividing fractions. We discuss these topics in order to make sense out of unit rates. All of this will be applied to how we represent proportions within tables, graphs, and equations.
Let's go over the worksheet for Lesson 6.
In this lesson, we begin to discuss table representations for proportional reasoning. Our goal is to apply our thinking about ratios and proportional with the organization of tables.
Let's go over the worksheet for Lesson 7.
In this lesson, we continue our work depicting proportional relationships with representations by discuss graphs. We try to understanding how the slope connects with the constant of proportionality.
Let's go over the worksheet for Lesson 8.
In this lesson, we finalize our work on representations by discussing equations and how they relate to proportional reasoning. By using tables and graphs, we can see how variables play a role in modeling proportions with equations.
Let's go over the worksheet for Lesson 9.
In this lesson, we take reflective approach on what we've covered in this unit and try to make connections between ratios, proportional reasoning, and the representations we covered. This unit is a great first step in developing mature mathematical thinking about how we can model the real world with mathematics.
Let's go over our final worksheet for the Proportional Reasoning Unit!
