** Match Descriptions with Equations.**

**Cards have proportional relationships represented 2 different ways: as descriptions and equations. Match a description with an equation.**

**Explain how you know it’s a match.**

——————————————————————————————————————————————

** Match Diagrams with Equations.**

**Match each diagram. There may be more than 1 unmatched equations.**

Draw a diagram below for one of the unmatched equations.

** Complete a Table of Relationships.**

Complete the table to show the total distance walked in each case.

- Jada’s pet turtle walked 10 feet, and then half that length again.
- Jada’s baby brother walked 3 feet, and then half that length again.
- Jada’s hamster walked 4.5 feet, and then half that length again.
- Jada’s robot walked 1 foot, and then half that length again.
- A person walked feet and then half that length again.

(1). Explain how you computed the total distance in each case.

(2). Two students each wrote an equation to represent the relationship between the initial distance walked () and the total distance walked ().

Mai wrote =+ ·

Kiran wrote = ·

(3). Do you agree with either of them? Explain your reasoning.
