Pre-Assessment Task Directions• Spend 15 minutes working individually on this

task. • Read through the task and try to answer it as

carefully as you can. • Show all your work so that I can understand

your reasoning. • Don’t worry if you can’t complete everything.

There will be a lesson that should help you understand these concepts better.

• Your goal is to be able to confidently answer questions similar to these by the end of the next lesson.

Whole Class Introduction

Describe the x-intercept, y-intercept, and slope in context of the problem.

Collaborative Activity Instructions Day 1

• Each group gets 2 card sets. Each situation has six cards. Your group will work to match descriptors to the equation and graph.

• Each group presents the situations to the teacher or to another group.

• Glue both completed situations to construction paper – one on each side.

*Extended Activity: After completing the above activity you will be provided a blank master. Develop another set of cards.

Collaborative Activity Instructions Day 2

• You will receive four samples of student work. • Make necessary corrections to each sample. • Be ready to explain why the correction was necessary

in plenary discussion.

Plenary Discussion Questions

• For this problem, what does the x-axis represent? What does the y-axis represent?

• In context of this situation, what does the y-intercept mean? What does the x-intercept mean?

• In context of this situation, what does the slope represent? How is slope calculated? Can you read it from the graph?

• Explain what a specific point on the graph means in context of the problem.

• Why are the points on the graph connected (continuous)?
