IM 8 Ch8 Closure
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 Ch8 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
While playing the game, ask your teammates the following questions:
How do we determine compound interest?How do we find simple interest?How is the interest growing?
How can we see this in the interest expression?
THE INTEREST GAMEToday you are going to play a game with your teacher. Your team’s goal is to have more
money in your account than any other team at the end of the game. You will start with an account balance of $1000. You will record your work and your balances throughout the game on the Chapter 8 Closure Resource Page A. Your team will also need an envelope containing interest rate cards.
To start the game, your teacher will select a card that gives you a time. Record the starting balance and time in the first section on your resource page. Then, as a team, pull a card from the envelope and compute the interest on your account based on the card and the time given to you by your teacher. When you have finished with a card, you will leave it on the desk. Transfer your new account balance to the starting amount in a new section on the resource page. Your teacher will then give you a new time and you will draw another card from your envelope. Your teacher will tell you how many cards to select during the course of the game.

How can we see this in the interest expression?
THE INTEREST GAME (continued)
When playing the Interest Game, you were trying to get the most amount of money in your team account.
What was your final amount?
Did you do more compoundinterest or simpleinterest problems?
What do you think made the most difference in the amount of money you made, the interest rate or the kind of interest earned (simple or compound)?

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
