HOW TO USE FRACTION DESIGNER

With Fraction Designer you can make your own fraction examples. Let's say you wish to see how the fractions 3/4 and 3/5 compare in size. With Compare with Circles just enter the two fractions, press the <OK> button and there they are:
Compare Circless
With Compare with Circles you can uncheck EXPLAIN and SHOW INPUT to ask your students to write a sentence that explains the picture. Or you might want to draw an image where students can shade in the fraction. With Compare with Circles you can uncheck SHOW COLOR and you will get an image that can be colored in:

With multiplication,you might want show what the product 2 1/2 X 2 1/2 looks like. With Multiply with Lines you can make an array of the product: Notice how the product 6 1/4 can by found by adding the 4 whole units, 4 half units, and the 1/4 unit. See more suggestions for demonstrating some important mathematics principals with the Number System Properties page.

You can uncheck EXPLAIN and ask the students to add up the rectangles in the array. Shown are four whole rectangles plus four 1/2 rectangles plus one 1/4 retangle for a total of 6 1/4 rectangles.

These Designer pages enable you to control the fraction image should you want to study for yourself or demonstrate for others.


To The Learner:

If you are beginning to learn fractions, start with the Identify Fractions programs and continue to Rename Fractions, Compare Fractions, Add Fractions, Subtract Fractions, Multiply Fractions, and Divide Fractions. Experiment with different patterns by increasing and decreasing the size of fractions.

You can use this Fraction Designer to see how naming, renaming, comparing, adding, subtracting, multiplying, and dividing are modeled.

There are helpful suggestions on the INSTRUCTION section of each page.


To The Teacher:

Demonstrate examples with a classroom projector. You can show suggested number patterns given on the INSTRUCTION section of each page. Each program will allow you to remove the answer should you wish to question students in class.

With Windows XP™ computers you can make worksheet examples by pressing the <Print Screen> button on the keyboard. This copies the screen into Windows Clipboard™. You can then paste the image into Windows Paint™ or into your favorite imaging program.

Each program will allow you to turn off the colored answer, the explanation and even the numbers you input, allowing you to ask the student how to simplify any modeled fraction example.

Windows 7 users can use the Snipping Tool™ to capture any part of the screen you wish. These images can be edited and saved in PNG, GIF(recommended) or JPEG formats.

To take a screen shot with theI PAD first press the Sleep/Wake button at the top right of the Ipad. While holding the Sleek/Wake button press and release the round Home button at the bottom of the screen. You should see a photo of the screen by going to the Home page and pressing the Photos icon.
