**Instructions for Use**

Comparing
Fractions with Unlike Denominators lets your child compare the size
of fractions with unlike denominators.

To use Comparing Fractions with Unlike Denominators , click the 'Start'
button. Two fractions appear in the text boxes. Click either the 'More
Than', 'The Same As' or, the 'Less Than' buttons to make the statement
true.

Comparing
Fractions with Unlike Numerators and Denominators lets your child
compare the size of fractions with unlike numerators and denominators.

To use Comparing Fractions with Unlike Numerators and Denominators
, click the 'Start' button. Two fractions appear in the text boxes.
Click either the 'More Than', 'The Same As' or, the 'Less Than' buttons
to make the statement true.

Comparing
Fractions prompts your child to solve fraction problems using models
and a number line.

To use Comparing Fractions, find the common denominators by clicking
the up and down arrow buttons below each graphic to change the number
of sections it is divided into. When there are no black lines in the
middle of the graphic (only yellow lines), the new denominator divides
the original fraction with no remainder.

Change the number of parts that each graphic is divided into until
they are equal, and there are no black lines in the graphics.

When the common denominator is found, click in the boxes to the right
of the equals signs ( = ) and use the keyboard to enter the equivalent
fractions. Click the ' Check ' button. If the answer is correct, a number
line will be displayed. If the answer is incorrect, a message will display
the error.

After the equivalent fractions are identified, a number line appears.
Click on the number line points that represent the equivalent fractions.
If the answer is correct, a dot will be displayed on the number line.
If the answer is incorrect, a hint will be displayed.

When the equivalent fractions on the number line are identified, enter
a fraction that is between the two fractions marked. Use the up and
down arrow buttons to the right of the number line to change the number
of divisions on the number line. Then, enter the fraction in the boxes
above, and click the 'Check' button. A message will display if answer
is correct or not.

Click the 'New Fractions' button below the workspace to begin a new
problem.
