Title: F‐LE & A‐SSE Linear & Exponenal Models Date:
Learning Target (Day 1 of 2)
By the end of the period, I will interpret linear and exponential functions for simple and compound interest problems.
I will demonstrate this by completing Four‐Square Notes and by solving problems in a pair/group activity.
Today we will investigate two ways to invest money:
Simple Interest and Compound Interest.
What is the difference between simple & compound interest?
Simple interest calculates a percentage of the original investment amount and adds it on each year.
Compound interest calculates a percentage of the amount in the account.
Storm Check (Think, Write, Discuss, Report)Questions on which to ponder and answer:• How are the two images similar?• How are they different?• How can these two images be related to math?

Group Poster InstructionsOrganize your cards into six groups:
P Investment CardsF Formula CardsG Graph CardsT Table CardsS Statement Cards
These 6 groups will be your columns for organizing your poster:Investment Formula Graph Table Statement
We will start matching the Investment (P) cards and the Formula (F) cards.
You have two sets of cards, one with descriptions of investment plans and one with the formulas. Some of the investment plans use simple interest and some use compound interest. Using what you have learned from our discussion, take it in turns to match a formula with a corresponding investment plan. There are two spare investment plan cards. Write on the blank cards the formula for these two plans.
Group Poster InstructionsThe 6 groups should be your columns for your poster:
Investment Formula Graph Table Statement
Review your poster to make sure ALL the elements in EACH ROW reflect the same investment.
How does the graph of simple interest differ from the graph of compound interest?
The graph of simple interest differs from the graph
of compound interest in that __________________
