Mixed to Fraction with Circle Models uses circles 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 then 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.

On the left is a <SHOW COLOR> button. Uncheck the button to turn off the red color on the circle. 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 circle should be shaded.


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.


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.
