CPM Materials modified by Mr. Deyo

The activities here offer you a chance to reflect about what you have learned during this chapter.  

As you work, look for concepts that you feel very comfortable with, ideas that you would like to learn more about, and topics you need more help with.

By the end of the period, I will apply different problem‑solving strategies and relect on what I have learned in this chapter.

I will demonstrate this by completing Four‑Square notes and by solving problems in a pair/group activity.

SUMMARIZING MY UNDERSTANDING

Part 1: Answer the question provided in each section of the Slope GO.  On the next page, work with your team to write six “Who, What, When, Where, Why, How?” questions about slope. 

Part 2: Follow your teacher’s directions to pair up with students in another team and trade GO questions to answer. 

Part 3: Be ready to contribute your team’s ideas to a class discussion.  On your own paper, make note of new ideas about slope.

This section gives you an opportunity to show what you know about certain math topics or ideas.  In this case, you will be solidifying some of your ideas about slope.Follow the directions below to demonstrate your understanding of slope.
