Some videos have a ‘PAUSE’ moment, at which point the teacher or learner can choose to pause the video and try to answer the question posed or calculate the answer to the problem under discussion. Once the video starts again, the answer to the question or the right answer to the calculation is given.
We suggests a number of ways to use the video lessons. These include:
Watch or show a lesson as an introduction to a lesson
Watch of show a lesson after a lesson, as a summary or as a way of adding in some interesting real-life applications or practical aspects
Design a worksheet or set of questions about one video lesson. Then ask learners to watch a video related to the lesson and to complete the worksheet or questions, either in groups or individually
Worksheets and questions based on video lessons can be used as short assessments or exercises
Ask learners to watch a particular video lesson for homework (in the school library or on the website, depending on how the material is available) as preparation for the next days lesson; if desired, learners can be given specific questions to answer in preparation for the next day’s lesson
1. Introducing Future Value Annuities
This video gives brief description of what future value investment or annuities are and the derivation of the future value formula from the sum of the geometric formula.
2. Working with Future Value Annuities
This video determines the equal regular investment (x). It highlights the fact that if you know the amount that you need (the future value) and the time and interest rate, you will be able to determine the equal regular payments to obtain the future value.
3. Introducing Present Value Annuities
This video starts by covering the loan options available. It explains the pitfalls of taking out loans with organizations that are not legal or trustworthy. This is followed by the derivation of the present value formula from the sum of the geometric series.
4. Working with Present Value Annuities
This video emphasises determining the equal regular payments of the loan. It highlights the fact that if you know the amount that you need and the time and interest rate, you will be able to determine the equal regular payments.
5. Determining the Investment Period
In this video, we discuss how the logarithmic function relates to the exponential function. We extensively use the reflection in the line y=x. We explore the asymptote and the x intercept.
6. Balance Outstanding on a Loan
In this lesson students are shown how to determine the Balance Outstanding on a loan after making a certain number of payments.
