Instructions For Investors

Dear Investors,

Thank you for taking time from your busy schedules to help us with our math project.


I am a math teacher at at Oakland High. I am currently working on my National Boards Certification via a support group at Stanford. For one of the portfolio entries, I needed to create project involving the community.

The project I created is for my Precalculus class. The students in this class are the best and brightest Oakland has to offer. Most of the students are 11th graders, but there are a few 10th graders and one senior.


We currently working on exponential and logistic functions. This project focuses on a section called The Mathematics of Finance. In the past, students haven't fully understood how powerful mathematics can be when applied to the world of finance. Also my students come from poor backgrounds and don't have access to people in the finance industry.


My students will create presentations on formulas and concepts commonly used in finance.

Each presentation will include:
  • The derivation of the formula
  • A numerical example
  • A graphical example
  • An algebraic example
  • A real world example

The presentations will be on one of the following 6 topics:

1. Interest Compounded Annually
A = P(1 + r)n

2. Interest Compounded k Times per Year
A = P( 1 +( r/k) )kt

3. Interest Compounded Continuously
A = Pen

4. Annual Percentage Yield
The percentage rate that, compounded annually would yield the same returns at the given interest rate with the given compounding interest.

5. Annuities - Future Value
FV = R  (1+ i)n  - 1

6. Annuities - Present Value (Loans and Mortgages)

PV = R  1 – (1 + i ) –n

How we would like you to help:

1. There will be six presentations in total. We would like each volunteer to choose one of the six topics listed above.
2. The students will need one example of how these formulas or concepts are used in investing. We are looking for a general example, not specifics of course : ).
3. The students will also be asking you background questions.
For example: Where did you go to school? How did you become involved in finance? Do you have any advice? etc.

You can respond in one of the following 3 ways.

1. Respond directly on the Voice Thread presentation via webcab, audio or by typing.
Please see for instructions.
2. Respond in the comment section of the blog entry.
3. Email a response to

The presentations will be available online on Friday March 23rd, and we would like you comment by Tuesday, March 27th.

Thank you very much for your time and consideration. It is greatly appreciated!
