Instructions for Use
Fraction Bars helps students add 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 students 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 students to manipulate and compare the size of the sections in the bars.
