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!
