Graphing Concepts and Ratios

In this video, students are introduced to Go Math Module 7.1, focusing on ratios, rates, tables, and graphs. The lesson is divided into two days, with this video covering day one. The teacher explains a focus problem involving a chart of salt water and regular water, demonstrating how to calculate rates and write ratios. Students learn to create equivalent ratios in fraction form and graph ordered pairs on a coordinate plane. The lesson emphasizes using multiplication and division to find unit rates and equivalent ratios, and concludes with instructions to continue practice in the textbook.

What is the ratio of salt water to regular water for the first set of values?

• 3 to 150

• 4 to 200

• 5 to 250

• 2 to 100

How can you express the ratio 2 to 100 in fraction form?
