Portfolios are longer assignments (They should take about an hour.) that need to be submitted in a drop box in the lesson. They may be done on paper and then a picture may be taken of the paper and the picture may be submitted (If you don't have a camera, use the Camera app on your laptop.), or may be done using a computer program such as Word, Excel, or AutoDesk Sketchbook. Look here for special instructions and help files and video recordings.
Unit 3 Transformations
This portfolio is a worksheet you print, fill out, take a picture and submit. You will find the Let's Dance worksheet in the lesson. The video below explains how to complete the questions and explores the concepts in Desmos.com.
Unit 5 Exponential Functions
You will find the worksheet for this assignment in lesson 6 of unit 5, on slide 8. Download and print the worksheet. Then complete it, take a picture of it and submit the picture in the drop box. Alternatively, you may complete the worksheet in Excel, Word or a combination, or another word processor or spreadsheet. In any case, make sure to answer each question on the worksheet. The worksheet explores the compound interest formula A = P(1+r/n)^(nt), examining closely the effect of the various parameters in the formula. The video below walks through the worksheet, explaining the various questions and the concepts behind them.
Unit 6 Conic Sections
You may find the worksheet for this portfolio in the lesson. Make sure to download and print it, and fill it out. It is possible to fill it out electronically, or to answer the questions and paste the examples in a Word document. I recommend using Desmos for fitting an equation to a picture, as I demonstrate in this Video. Do note, the last part of the portfolio asks you to double or half the focus-vertex distance. This is ambiguous in the case of a circle. So please do not use a circle for the last part.
