Enter into the Geometry icon

from the MENU.

 Set up the View Window to those shown in the screen snaps below.  

Make sure that you have the Integer Grid on by tapping in the box so that a √ is entered in the box.

If you have the axes on, as illustrated below, then note where the origin (0,0) is and then turn the axes off.

Select the line segment tool.

Create a square starting at (0,0) and then progressing to (3,0) → (3,3) → (0,3) returning to (0,0).

See the screen snap to the right illustrating the square ƒXABCD.

Tap on Menu at the bottom of the screen and then split the screen by tapping

on the arrow here and selecting the geometry Icon.

In the Geometry Window tap the stylus on each of the points labelled A, B, C, D and then keeping the stylus on the geometry screen drag it to the left side of the working box in the Main window. [Note: You will see a rectangle form as you drag these points up.] Then take the stylus off the screen. A matrix illustrating these four points will appear. See the screen snap on the right.

Clear the screen in the Geometry window by selecting Edit and then Clear All.

Now change the matrix

     0   3   3   0               0   2   2   0

     0   0   3   3     to       0   2   2   0    by editing this in the Main window. See the screen snaps below.

Now, drag over the matrix to highlight it and then drag it into the Geometry window.

[Remember to:  Clear the screen after each drawing and matrix.]

Practice A:

Try to create the following and viewing their matrix.

Practice B:

Creating a matrix in the ¡¥Main¡¦Icon.

Bring up the Keyboard and select 2D tap on the double arrow at the bottom to bring up the keyboard screen illustrated in the next screen snap.

To select a matrix, these are a combination of these two tools. Have a practice with these two tools to see how you can create the required matrices.

In the example shown

6 × of 

1 × of  

Try to create the following matrices and viewing their picture.

Have fun!

Generating a sequence on the Classpad 300.

This resource was written by Derek Smith with the support of CASIO New Zealand. It may be freely distributed but remains the intellectual property of the author and CASIO.

A sequence is an ordered list of objects (or events), it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence.

A sequence may be denoted <a₁, a₂, a_3, a₄ ...>. The notation <a_n> is usually used.

In the Main icon,   tap with the stylus on the Action ¡¥drop-down¡¦ menu then List-Create and then seq.

Example: You want to create the first 10 members of the sequence <x²>.

Enter after seq( the following: x^2,x,1,10,1) When you press [EXE] the list will appear in set brackets, i.e.{}. See the screen snaps below. Use the ¡¥Right Arrow¡¦ to view terms that are ¡¥off the screen¡¦.

Examples:

1. Create the first 10 members of the sequence <x²+2>.
2. Create the first 5 members of the sequence <x-2>.
3. Create the first 5 members of the sequence <3-r>.
4. Create the 10^th to the 20^th members of the sequence <2p+4>.
5. Create the first 8 members of the sequence <3x²+2/x>.
6. Create the 100^th to the 105^th members of the sequence <(3k+1)/k>.

Using ¡¥Verify¡¦ on the Classpad 300.

This resource was written by Derek Smith with the support of CASIO New Zealand. It may be freely distributed but remains the intellectual property of the author and CASIO.

Checking to see that, your algebraic working or numerical calculations are correct using Verify.

From the MENU tap with the stylus on eActivity, then on the Action ¡¥drop-down¡¦ menu then Verify [at the bottom of this list].

To see what happens, type in 45 and then 9×5 in the next box and press [EXE]. You will view (very briefly a smiley face, J.

Make a deliberate mistake on the next line and see what happens.

Try some factorising and change the R to C.
