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.
IM 8 Ch7 Closure
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.

Ryan
CL 7121. Ryan and Janelle are driving from different locations to meet at Mammoth Lakes. When they each stopped for lunch, they called each other on their cell phones. Ryan had traveled 245 miles in 3.5 hours. Janelle had driven 260 miles in 4 hours.
Janellea) How fast was each person driving?
b) If Janelle originally started 575 miles from Mammoth Lakes and continues traveling at the same rate (from part (a)), how many more hours will it take her to arrive at her destination?

WHAT TOOLS CAN I USE?You have several tools and references available to help support your learning – your teacher, your study team, your math book, and your Toolkit, to name only a few. At the end of each chapter you will have an opportunity to review your Toolkit for completeness as well as to revise or update it to better reflect your current understanding of big ideas.
The main elements of your Toolkit should be your Learning Logs, Math Notes, and the vocabulary used in this chapter. Math words that are new to this chapter appear in bold in the text. Refer to the lists provided below and follow your teacher’s instructions to revise your Toolkit, which will help make it a useful reference for you as you complete this chapter and prepare to begin the next one.Learning Log Entries
