Course Objectives


 * Primary Objectives- By the next class period students will be able to:
 * Find the future value of an annuity;
 * Determine the payments needed to meet future obligations.


 * Sub Objectives- The objectives will require that students be able to:
 * Find the rate per period and the number of payment periods;
 * Find simple and compound interest.


 * Difficulties- Students may have difficulty:
 * Determining the rate per period as opposed to the annual interest rate.
 * Determining the number of payments as opposed to the number of years.
 * Using the graphing calculator for the exponents.
 * Using the graphing calculator with parenthesis in the correct place.


 * Real-World Contexts- There are many ways that students can use this material in the real-world, such as:
 * Solve real life application problems using the future value of an ordinary annuity and sinking fund payment formulas.

THE CHALLENGE

You have had your first child and are concerned about paying for his/her college education. How much money do you need to invest each month to be able to pay for his/her college education 18 years from now?

GENERATE IDEAS

How much does it cost now for a college education and how much will it cost in 18 years? What is the current rate of investment? What if you have another child in 3 years? What if the family has financial problems?

MULTIPLE PERSPECTIVES

Lecture over formulas needed. Work in groups of 3-4. Bring in an investment person (guest speaker).

RESEARCH & REVISE

Go online to research current rates. Check tuition changes over the past several years. Research risks of various investments.

TEST YOUR METTLE

Assign problems on investments.

GO PUBLIC
