**Instructions for Use**

Fraction
Bars helps your child compare fractions within a whole using fraction
bars.

A fraction bar appears when the applet opens. To use Fraction Bars,
determine the size of the denominator by clicking on the up or down
arrows beside the fraction bar. Click the 'fdrp' button. This button
allows your child to see the sections on the fraction bar as fractions,
decimals, ratios or percentage - click the 'f' for fraction display.
Determine the size of the numerator by clicking on the sections inside
the fraction bar - they change colour from green to yellow. Click on
the bar button to make up to 5 new fractions bars. Click the 'Reset'
button to start again.

Using several bars together at one time allows your child to manipulate
and compare the size of the sections in the bars.

Play
the Fraction Track gives your child as a visual model for comparing
fractions.

Play the Fraction Track is a game for two players. To use Play the
Fraction Track, the first player begins by moving one or more blue markers
along the tracks, either forward or backward, so that the positive and
negative distances moved by all markers add to the amount shown in the
fraction box. When a piece is moved, an outline is shown in its starting
position for that turn. Click on 'Finish Move' to let the next player
take a turn. If the markers are incorrectly added to the fraction shown
on the box, an error message is displayed if the move was not correct.
When a correct move is entered, the second player then similarly moves
one or more red markers. If a player cannot complete a move, click on
the 'Pass' button. The first player to move all the markers to the right
side of the Fraction Track board wins!
