Topic

Ratios

Description

This example demonstrates the use of double number lines to solve a ratio problem involving orange and lemon juice. The juice mixture uses a ratio of 2 parts orange juice to 1 part lemon juice. Given 6 cups of orange juice, students are asked to determine the amount of lemon juice needed. The solution involves aligning the double number lines at the amount of orange juice and reading the corresponding amount of lemon juice, which is 3 cups.

Double number lines are an effective tool for visualizing and solving ratio problems. They provide a clear representation of the relationship between two quantities, making it easier for students to understand and manipulate ratios. In this collection of examples, students are exposed to various scenarios involving juice mixtures, allowing them to practice applying the concept of ratios in different contexts.

Presenting multiple worked-out examples is crucial for students to fully grasp the concept of ratios and double number lines. Each example builds upon the previous one, gradually increasing in complexity and introducing new variations. This approach helps students develop a deeper understanding of the topic and enhances their problem-solving skills.

Teacher Script: "Let's look at this juice mixture problem. We have a ratio of 2 parts orange juice to 1 part lemon juice. If we have 6 cups of orange juice, how can we use the double number line to figure out how much lemon juice we need? Notice how the lines are aligned and how we can easily read the corresponding values. This visual tool helps us see the relationship between the two quantities and solve ratio problems more easily."
