Lesson 2

Introduction to Main and the Soft Keyboard

Welcome

In this lesson, we will eventually explore the ClassPad’s Main

application and the soft keyboard. To begin, though, we need to cover

some terminology that is common to all PC applications and some

specific to the ClassPad.

Lesson Goals

• To learn basic window terminology

• To become comfortable using the Main Application

• To learn how to use the soft keyboard

• To learn how to change number format

In Lesson 2, you will learn how to:

• Identify specific parts of a window

• Use the ClassPad’s soft keyboard

• Store a number in a variable and clear variables

• Use the Main application’s buttons and menus

• Change number format

• Change from base 10 to other bases

Upon completion of this lesson, you will be able to

answer the following questions:

1. What is an application?

2. What are two ways to open the soft keyboard?

3. How do I change from the abc keyboard to the 2D keyboard?

4. What does the

button do?

5. What does the

button do?

6. What are mode settings and how do we change them?

7. What information shows in the status bar?

8. What is a single variable?

9. What is the imaginary unit?

Time required

About 60 minutes.

for Version 3 Basic Edition Lesson 2 Introduction to Main and the Soft Keyboard Welcome In this lesson, we will eventually explore the ClassPad’s Main application and the soft keyboard. To begin, though, we need to cover some terminology that is common to all PC applications and some specific to the ClassPad.
PAGE 2
Getting Started What is an application? In the computer world, we define application as a computer program with a user interface. You can think of an application as any program that you can open on your computer and do work in. The ClassPad Manager is an application with other applications inside. Most of its components (or parts) are the same as other PC applications; only a few are unique. PART I [Important] Become familiar with basic window terminology.

System Menu Button ( ) Opens a menu that looks similar in all ClassPad applications. The System menu provides you with many dialogs to set ClassPad modes and other window options. Menu Bar Provides a row of menus that you can open and select commands from. The ClassPad’s “Menu bar” will change for each different application.
PAGE 4
Window Border A box or edge defining an application’s work area. When more than one window is open, the active window (window with focus) will have a bolder border. You will learn a lot more about window borders and focus in the next lesson. For now, please just notice the difference. This window is active (has focus). Notice the toolbar and bolder window border. Notice the toolbar and window border changed. This window is active (has focus). Scrollbar Provides a way to “pan” your window.

PART I Practice Exercises Before beginning the practice exercises, open a word document, type in the following information and then save it as Lesson2 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 2 1. Open your ClassPad Manager, if you have not already. 2. Click 3. Open the Main application. 4. Evaluate 32.7 – 18.9 (type it in and press EXE or Enter). 5.

PART II In this part, you will begin exploring the ClassPad’s soft keyboard. As you will see, the soft keyboard is not just an everyday keyboard. It does contain a regular keyboard, but also many other very useful keys. 1. 2D Math Page Sometimes in the instructions you will see a “/” between words. The “/” is a shorthand notation commonly used when writing instructions for working with menus. For example, Edit/Clear All indicates that you should open the Edit menu and select Clear All. a.
PAGE 7
3. Single Variables In Algebra we learn that no symbol between variables (letters) means multiplication. The ClassPad also thinks this way when we use its single variables (bolder letters). Sometimes, however, we want to define a variable with more than one letter. For example, let width = length – 12. To do this, we can use letters from the regular keyboard. a. Clear your window (select Edit/Clear All) b. Click the 9 or tab ) c. Click the VAR button (along the bottom). d.

PART II Practice Exercises 1. Open the Main application, clear your window and then open the system ) and select Keyboard. This is another way to open and close menu ( the keyboard. 2. Using 2D math, input and evaluate [Hint: After inputting , press the right arrow key to get out from under the square root. Notice the blinking cursor becomes larger.] 3. Change your answer to a decimal. 4. Get a screen capture and paste it into your Lesson2 document (under a title of PART II). 5.

PART III In this part, you will learn another way to store values, how to use the one finger toolbar button, change base and change the form in which your numbers display. For example, always show results as a decimal. Or, you may want to work with angles in degrees instead of radians. To change most settings we can use the Basic Format dialog box or just click the status bar. We usually call these format settings “mode settings”.

2. Status Bar and One Line at a Time a. Notice your status bar b. Click Decimal to toggle it back to Standard c. Click on your first math line and then the button d. Notice only the 1st output changed *One line at a time please! **Or, press EXE to reexecute everything. Just tap it! 3. Changing Base What does “base” mean? It has to do with place value. Well, as you know, 234=2*100+3*10+4. This can also be written as 234=2*102+3*101+4*100 (note that any # raised to the 0 power equals 1 except 00).

PART III Practice Exercises 1. Open the Main application and select Edit/Clear All. Notice the status bar changed to show all modes again (no longer in Bin mode). This is a good thing! 2. A flea traveled 3.76 yards on the first day of its journey, 2.57 yards on the second and 1.99 yards on the last day. Using the Main application, calculate the total distance traveled. 3. To the nearest tenth, how far did the flea travel? Hint: Change your mode setting to Fix 1 and re-execute line one to display a decimal.

PART IV Written Exercises Please copy and paste the following questions into your Lesson2 document and answer them. 1. What information shows in the status bar? 2. What are two ways to open the soft keyboard? 3. What does the button do? 4.
