# Use Appropriate Tools

Today you will explore and compare glide ratios of things that fly.

In this unit, you have used tape diagrams, double number lines, ratio tables, and graphs to represent ratios, make comparisons, and solve ratio problems.

Whenever you work with ratios, you should think about the tools that are available to you and choose the one(s) that you think will be the most useful.

- How do you think your work in previous lessons might help you represent and compare ratios?
- Watch this video as Jan, Carlos, and Mia use appropriate tools to explore wingspan and glide ratios.
