Lesson 7
Getting Started (View, Edit and Email eActivities, continued)
Most of this lesson will be hands on. Before beginning, please follow the steps below to download Lesson_07.vcp to your computer. Note that when you open Lesson_07.vcp, it becomes your current active file.
1. Download the Virtual ClassPad file (vcp file)
- Click Lesson_07.vcp
- Choose the Save or Save As… option
- Open the Save in dropdown box (near top)
- Browse to your My Documents folder and select it
- Select the CASIO folder and then the ClassPad Manager folder
- Click Save
- Click Open Folder
- Double click on Lesson_07.vcp to open it
2. Alternative way to open a Virtual ClassPad File
- Right click on your ClassPad (a "context menu" will appear)
- Select File and then Open...
- Browse to your Lesson_07.vcp file (It should be in My Documents/CASIO/ClassPad Manager folder)
- Select Lesson_07.vcp
- Click Open
3. Check to see that Lesson_07.vcp is Active
- Right Click on your ClassPad Manager
- Select Exchange Window
- Check that Lesson_07 is in the Active Document folder
- Close the Exchange Window to return to the ClassPad emulator
Part I
In this part, we will practice using the Notes application and also review a few topics from earlier lessons. Notes is a very simple text editor. As its name indicates, it is used to write notes, questions or answers.
1. Inserting a Notes Application
2. To Delete an Inserted Application
3. Working with Notes
4. Exploring what happens to y=Ax^2 as A increases
5. Having fun with the graph of y=Ax^2 as A changes
6. Continuing our exploration of y=Ax^2 as A increases
So, what does happen to a parabola when we increase the leading coefficient? But, first…
[Important] How do you get back to eActivity?
- ANY window opened inside another can be closed by giving it focus and clicking on the
button in the upper right corner. You can also select Close from within the system menu (
).
What are parent and children windows in the programming world?
- Parent Window Since we opened eActivity first, eActivity is the parent window. This means that it is always in the background, or until you select
or 
from the icon panel. Notice the upper right x is grayed out when eActivity has focus. - Child Window When we insert another application within eActivity, you can think of it as a child of eActivity. Child windows can be closed.
7. Answering our exploration of y=Ax^2 as A increases

Practice Exercises
Before beginning the practice exercises, open a word document, type in the following information and then save it as Lesson7 in your CASIO folder within My Documents:
- Date: (enter today's date)
- To: (put your instructor's name here)
- From: (put your name here)
- Re: Lesson 7
- Please open the eActivity application and clear the window.
- Open the eActivity titled L7_PartI_a in the Lesson 7 folder. Don’t open L7_PartII_a by mistake! In this eActivity, you will learn another way of exploring parabolas with the ClassPad.
- Expand the Geometry strip and then change the leading 2 to a -2. Press EXE.
- With the Geometry window expanded, get a screen capture. Paste the screen capture in your Lesson7 document (under a title of PART I).
- Experiment with the leading coefficient by putting in different values (positive, negative, large and small values). You can reopen L7_PartI_a if you need to start fresh at any time.
- Expand the first Notes strip (labeled Question 1 Click). Type in an answer to the question using a complete sentence.
- With your Notes strip expanded and your answer showing, get a screen capture. Add two blank spaces following the first screen capture and then paste this one.
- Expand the second Notes strip (labeled Question 2 Click). Read the question and then re-open the Geometry window.
- Experiment with the constant at the end (the c value). Remember that the + and – keys will zoom your graph window in and out quickly.
- Expand the second Notes strip again (labeled Question 2 Click). Type in an answer to the question using a complete sentence.
- With your Notes strip expanded and your answer showing, get a screen capture. Add two blank spaces following the second screen capture and then paste this one.
- Save your work as an eActivity named L7_PartI_a_your initials here. For example, L7_PartI_b_dw.
- Open the next eActivity, L7_PartI_b. In this eActivity, you will work with another form for a parabola.
- Expand the Geometry strip and then change the 2 to a -1 and the ending 1 to 2. Press EXE. Your link should look similar to: y=3(x+1)^2+2 or y=3(x--1)^2+2.
- With the Geometry window expanded, get a screen capture. Paste the screen capture on the next line following the first three.
- Experiment with the numbers in the h position and k position by putting in different values (not too large, but try both positive and negative).
- Expand the Notes strip (labeled Question Click). Type in an answer to the question using a complete sentence.
- With your Notes strip expanded and your answer showing, get a screen capture. Add two blank spaces following the last screen capture and then paste this one.
- Save your work as an eActivity named L7_PartI_b_your initials here.
