Mathematics with Creative Designs on a Graphing TI - Calculator, The Beginner’

The Beginner’s Worksheet

(Linear functions in the slope-intercept form)

A design can be created on most of the TI graphing Calculators by using the following steps.

The linear function design can be created using the following steps:

·         Setting the viewing window: Press the key [ZOOM]. Select 6: Standard. Press the key [ZOOM] again and select 5; this will set the window in square settings. Be sure that your calculator is in degree mode.

·         Be sure that the axes are off: Press the key [2ND] then press [ZOOM] key and follow the screen.

·         Enter the following equations: Press the key [Y =] and enter the following equations.

·         Press the [GRAPH] key once the equations are entered.

The graphs on screen will look like: 

Sketch the graph on a paper and label the lines with their equations. Labeling the graphs helps beginners in writing the shading directions.

Labeled graphs 

To shade the area between the curves press the [2ND] key and then the [DRAW] and select 7: Shade(.

·         Write the shading directions in the order as follows:

.

·         Shading with different pattern and patres: Four different patterns can be created by entering one of the numbers, either 1 or 2 or 3 or 4. Enter 1 for vertical lines, 2 for horizontal lines, 3 for lines with negativeslope, and 4 for lines with positive slope.

·         The last parameter in the shading command, the patres, defines the spacing between the pixels. For distinct effect the spacing between the pixels can be adjusted by using 2, 3, 4, 5, 6, 7, or 8. [The number _]1[ is not recommended as number ]1[ will shade the area totally dark_].

·         Enter the following sequence of shade commands, one at a time. Press [ENTER] each time to execute the command. To be able to write, for example~,~ press [VARS], move to Y-VARS, press [ENTER] and select one of the “y” to be posted. Now try the following shadings.

         

The design, after each shading, will _] look like:

                                       

The final design on the screen will look like:

·         Writing Text: Press the [2ND] key and then the [DRAW]. Select 0: Text. Press the [2ND] key and then the [ALPHA] key to clock the Text option, position the cursor where you want your name to begin and write your name.

The Zero Key works as the space key as well as the key to erase any portion of the graph or the text while the [ALPHA] key is locked. Move the cursor to the portion of the unwanted graph and press Zero Key. Repeat this step until the unwanted portion of the graph is erased.

·         Store the design: Press the [2ND] key and then the [DRAW] key and move the cursor to STO. Select [1: StorePic *]and[ *]enter a number from 1 to 9, or 0 (zero). The picture will be stored by pressing [ENTER]

·         Recall the design: Press the [2ND] key and then the [PRGM] key and move the cursor to STO. The picture can be recalled by selecting 2: ReclPic and entering the same number where the picture was stored

One of the major challenges of the CCSS is to engage and motivate students for deeper conceptual understanding of mathematics. The natural way to achieve this challenge will be the best practice, which can be done by using technology providing visual approaches. The Designing approach provides teachers a unique tool to teach algebraic concepts by creating designs on a graphing calculator using equations of mathematical functions. The creative design helps students to enhance visual thinking. It helps students to understand and to apply Algebra, Geometry and Trigonometry concepts in creative and enjoyable way.The visual illustrations inspire and motivate students in the learning process. You can learn how to create a mathematical design on a TI-83, TI-84, TI-84 Plus, TI-Inspire, and more TI- Graphing Calculators.
