VISUAL FRACTIONS

September 29, 1999

Hi, Jim

I am moving Visual Fractions to a new site. Up to this time XOOM has provided
a free site, but XOOM puts an advertising frame across the top which takes room from the applications. Visual Fractions also has a domain name which is, of course, http://www.visualfractions.com.

From: http://www.visualfractions.com (September 29, 1999)

The following series of programs use number lines to help you visualize fractions and the operations on them.

A java enabled browser is necessary to run each program.

IDENTIFY FRACTIONS

Identify Fractions will give you instruction and practice in identifying numerators and denominators.

Play a game with fractions. Grampy's favorite game is hide and seek. Check it out at Find Grampy to play hide and seek with Grampy and Grammy.

RENAME FRACTIONS

Identify Mixed Numbers will give you instruction and practice in identifying whole numbers, numerators and denominators.

Mixed Numbers to Fraction Form will give you instruction and practice in renaming fractions from mixed number to fraction form.

Rename In Higher Terms will give you instruction and practice in renaming fractions in higher terms.

Rename In Lowest Terms will give you instruction and practice in renaming fractions in lowest terms.

Play another game with Grampy and Grammy. This game of hide and seek requires a mixed number in lowest terms. Check it out at Find Grampy-Strict to play another game of hide and seek with Grampy and Grammy.

OPERATIONS ON FRACTIONS

Compare Fractions will give you instruction and practice in comparing fractions by asking you to choose the larger of two fractions. The concept of least common denominator is introduced.

Add Fractions will give you instruction and practice in adding fractions. Each addend in this introductory program has like denominators.

Add Unlike Fractions will give you instruction and practice in adding fractions with unlike denominators. Common denominators are required to add the unlike fractions.

Add Fractions-Strict will give you instruction and practice in adding fractions with unlike denominators. The sum must be entered as a mixed number and in lowest terms.

Subtract Fractions will give you instruction and practice in subtracting fractions with unlike denominators. Borrowing to find a difference is introduced.

Subtract Fractions-Strict will give you instruction and practice in subtracting fractions with unlike denominators. The difference must be entered as a mixed number and in lowest terms.

Build cookies for Grampy at Cookies For Grampy. You will use fractional pieces of cookies to build whole cookies for Grampy.

Multiply Fractions will give you instruction and practice in multiplying fractions. Each example will have a mixed number times a whole number.

Multiply Fractions-Strict will give you instruction and practice in multiplying fractions. These examples will have a mixed number times a mixed number. The product must be entered as a mixed number and in lowest terms.

Divide Fractions will give you instruction and practice in dividing fractions. Each example will show visually how the divisor will fit into the dividend a whole number of times.

Divide Fractions-Strict will give you more instruction and practice in dividing fractions. Each quotient might be a number less than one or a mixed number larger than one. The quotient must be entered as a mixed number and in lowest terms.

Stay Tuned for another Cookies for Grampy game.

RESOURCES FOR TEACHERS

Check out Math Resources for mathematics resources for parents, teachers, and students.

The purpose of this web site is to help you to visualize fractions and the operations on them. Please let me know if you find Visual Fractions useful to you as a student or teacher. I especially would like to know how you are using these fraction applications.
