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

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.

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)?
