MIXED FRACTIONS INSTRUCTIONS

Mixed to Fraction with Number Line Models uses number lines to demonstrate renaming fractions from mixed form to fraction form.

Any whole number or mixed number can be written in fraction(a over b form) form such as seven fourths. Some textbooks call such a number where the numerator is equal to or greater than the denominator improper or top-heavy.

The very definition of a rational number uses the idea of fraction form. A rational number is any number that can be expressed as the quotient a/b of two integers, with the denominator b not equal to zero(0).

So a rational number is any number that can be written in fraction form as long as the denominator is not zero.

You can input any fraction with a value less than 7. The denominator must be less than 100. Press the <OK> button and the chosen fraction will appear in fraction form.

On the left is a <SHOW COLOR> check box. Uncheck the box to turn off the arrow and the red color on the number line. This will allow the learner to demonstrate the size of the fraction.

Uncheck the <EXPLAIN> check box to turn off the answer and the explanation. You can ask your students to complete the number sentence.

With <SHOW INPUT> unchecked, the fraction input boxes will act the same as password input boxes so students will not see the numbers you input.

With <EXPLAIN> and <SHOW INPUT> unchecked you can ask your students to write a number sentence that explains the picture.

With <EXPLAIN> and <SHOW COLOR> unchecked you can ask your students how the number line should be shaded.

Suggestions:

Demonstrate the numerator by counting each of the equal colored parts. So 1 3/4 will have 7 colored parts.

If you wish to see the fraction form of a whole number, type in a numerator that is a multiple of the denominator.

With <EXPLAIN OFF> and <HIDE INPUT> you have the opportunity to ask the student to write a math statement that shows the mixed form and the fraction form of the numeral from the fraction model.

WINDOWS COMPUTERS

You may copy the screen by pressing <Print Screen> on the keyboard. This copies the screen into Windows Clipboard™. The screen can then be pasted into Windows Paint™ or your favorite imaging program. Windows Paint™ will allow you to crop, print, or save the image.

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.
