Exploring Equivalent Ratios through Graphing

The video tutorial covers graphing and plotting equivalent ratios on a coordinate plane. It begins with an introduction to the concept and the learning target. The first example uses a field trip scenario to demonstrate how to create a table and graph equivalent ratios. The second example involves a Rainbow Loom, showing how to simplify ratios and plot them. The tutorial emphasizes the importance of linearity in graphs of equivalent ratios and concludes with a recap of key points, including ensuring graphs start at the origin.

What is the main goal for students in this lesson?

• To learn about different types of graphs

• To memorize the multiplication table of 12

• To plot and graph points related to equivalent ratios on a coordinate plane

• To understand the history of ratios

Why is it important for the line in a graph of equivalent ratios to start at zero?

• It's not important

• To make the graph look better

• To confirm the ratios are equivalent

• To ensure accuracy

How should you space out your graph?

• Plot points close together

• Use the entire graph space

• Space is not important

• Only use the center of the graph
