#### Here Fishy, Fishy!

Yolanda and Zachary each have some fish. Zachary gives Yolanda some of his fish, and now he has twice as many fish as she does. Students must utilize given information and apply proportional reasoning skills in order to figure out how many fish Zach gave Yolanda.

#### Steeper, Faster, Division, and Slope

What does "steeper" mean? What does "faster" mean? And how do these ideas connect to the idea of linear functions? This 3-part series explores these questions and helps students to understand why we divide when computing slope and what proportional correspondence has to do with it all!

#### Sharing Pencils

Sarah and Michelle are working on a class project using colored pencils. Given some information about the number of pencils that Sarah and Michelle had when they started, and how some sharing of pencils has taken place, students must employ proportional reasoning skills to determine how many colored pencils the girls now possess.

#### How Big or How Little?

This activity is designed to have students think about what it means to “keep it in proportion” – a very common phrase, but what does it mean?

#### Preheating the Oven

Students use rate of change ideas to predict how long it will take for an oven to preheat to 400 degrees. The youtube video may be used to bring drama to the lesson! A link to the video is here and also in the documents. https://www.youtube.com/watch?v=I2ooIWFAcII&list=UUiPlxONW80Z8rGpu3lSLwjg

#### Sugar Packets - Dan Meyer Three Act Task

The question is simple: How many sugar packets are in a soda bottle? The lesson hooks students immediately with the initial video clip of a man sitting in a restaurant downing packets of sugar one-after-another! The mathematics involved is proportional reasoning.

#### Capture-Recapture

Imagine that a city employee is given the task of counting the number of fish in a city pond in a park. The “capture-recapture” method may be used to approximate the number of fish in the pond. The employee could capture a number of fish, say 20, and tag them and release them back into the pond. Waiting until the fish have a chance to become mixed with the other fish in the pond, the employee can capture more fish. If the number of fish captured is 25 and 4 of them are tagged, we can use proportional reasoning to estimate the number of fish in the pond.
