2. 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. 2

3. Whole Class Introduction 3 xy 030 215 40 Describe the x-intercept, y-intercept, and slope.

4. Whole Class Introduction 4 Describe the x- intercept, y-intercept, and slope in context of the problem.

5. Collaborative Activity Instructions Day 1 5 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.

6. Collaborative Activity Instructions Day 2 6 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.

7. Plenary Discussion Questions 7 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)?
