Time required

About 60 minutes.

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 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.

Very useful button!

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

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”. Mode settings control how the ClassPad Manager handles math and other settings.

Important: What are your ClassPad’s mode settings? Your status bar (along

the bottom of this window) might say: Alg Standard Real Rad This means your ClassPad is set to:

• Algebra mode

• Standard number output

• Real numbers only

• Radian Mode (not degrees)

1. Basic Format Settings

a. Open Main and clear the

window

b. Evaluate 5/6 (notice the

result is exact)

c. Open the

select Basic Format

execute everything.

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*10 (note that any # raised to the 0 power equals 1 except 0

We work in base 10, but computers often work in b ase 2 or base 16. Base 2 is called binary and base 16 is called hexadecimal. For exa mple, 5 in base

2 is 101=1*2

+0*21+20. There are also many other bases that are common.

You could really write a number in any base you want to! For now, we will experiment with base 2 (binary) only. You may someday

find this useful! It is definitely fun to think in a different base.

a. Open Main and clear the

window

b. Click the 1

toolbar and select

n on the

c. Input 101+11 and

press EXE

d. Input 2 and press EXE e. Bin mode (base 2) only

knows 0 and 1!

f. Change 2 to 2d to let

the software know you mean base 10

g. Press EXE h. Note 10b=1*2

=2 (base 10)

+0*20

Notice the status bar shows Bin (short for Binar

+3*101+4*100

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 mo de). This is a good thing!

2. A flea traveled 3.76 yards on the first day of it s 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.

4. Get a screen capture and paste it into your Lesson2 document (under a title of PART III).

5. Complex number and real number results are sometimes different. “Complex” numbers occur when there is a negative under a square root.

6. Using 2D math, try to evaluate undefined in the real mode (notice Real shows in your status bar). If square roots are new to you, be patient, you will learn about them someday. For now, just experiment with the ClassPad.

7. Click Real in the status bar to toggle to Cplx or op en the Basic Format dialog box and check the box for Complex Format. Re-evaluate

you see sense does NOT mean non-existent; it means not a real number (not on

the real number line).]

8. Get a screen capture. Please add two blank spaces following the first screen capture and then paste this one.

9. Ok, time to explore the soft keyboard. Try to find two music note symbols within the soft keyboard (they look like:

[Hint: You will find them by looking in one of the pages that appear when you click a lower button on the abc page! Remember to click the back arrow button to get back and the down arrows on the right to see more of a page.]

Reflection Exercises

You have just completed the second lesson in ClassPad 101, g reat! Learning terminology is not as much fun as entering things into the ClassPad, but learning the terminology is important so that we can talk in a technical way! Try to review pages 2 and 3 until you are comfortable with each term. Or, you can print them so that you can refer to them quickly as needed.

Please take a few moments to copy and paste the following three questions at the end of your Lesson2 document and answer them.

1. Approximately how long did it take you to complete this lesson?

2. Which activity did you enjoy the most?

3. Did you find any part of this activity difficult to follow? If so, which part? Also, how did you overcome the difficulty?
