Exploring Connections
  Introduction | Calculating Interest | A More Efficient Method | Interest Calculator | Reviewing Connections | Your Journal


You've just explored a series of problems involving compound interest, with the purpose of examining your own awareness of connections. Now we'd like you to write about your experience. Answer at least one of the questions below, focusing on the topics that mean the most to you at this point in the course. As you make your journal entry, use the material you've just seen and read as a context.

Questions to write and reflect about:
  • Give examples of ways in which mathematical connections are important in the development of understanding of compound interest and related formulas. What is the difference, in the eyes of a struggling student or mathematically inexperienced adult, between the method used here –– working through the derivation of the formula –– or simply presenting the formula V = P(1 + r/n)tn?
  • Describe your experience and discoveries as you experimented with modifying the interest rate, time period, and principal. Did you make and test conjectures? How did you use technology? What are some of the observations you made regarding the impact of various values in the formula and their connections to real-life situations?
  • As you considered specific connections, what ideas did you have for working with students whose mathematical background might not allow them to work on this problem with ease? Describe specific ways in which connections of various types could be of help to such learners.
Three ways to write and reflect:
  • Use pen and paper.
  • Use a word processor.
  • Use the form below.
Be sure to save what you have written before you navigate out of the journal section.


Your work will be displayed in a printer-friendly format to enable you to print.

Thanks for writing in your journal. Please keep your entries in whatever format you choose -- you will find them useful for reference later.
