Fraction Bars is a software manipulative environment to support students in understanding fractional pieces, operations with fractions, and notions of fair share. Fraction Bars works with an area model using rectangles. Students are able to create rectangles of any size, and split them into smaller pieces to compare the resulting fractional pieces against each other.
Fraction Bars requires a browser with good HTML5 compatibility. The latest version of a major browser is strongly recommended. Although Fraction Bars works in a number of browsers, most testing has taken place in Firefox 22 and Chrome 28. If you have trouble, you might try using those.
