Fraction Bar Model Generator

Turn any fraction into a divided rectangle bar model instantly. Enter a numerator and denominator, and this tool draws a bar split into equal segments with the right number shaded in. It handles improper fractions by stacking extra whole bars, and it can show two bar models at matching widths so students can compare fractions directly, even with different denominators.

When teachers reach for a bar model

Bar models are the standard visual for Singapore Math and most modern fraction curricula because they line every fraction up on the same straight edge. Reach for this generator when you need a comparison between two fractions, a clean strip diagram for a worksheet, or a visual that will still make sense once you move on to fraction addition and subtraction.

Frequently Asked Questions

Common questions about the fraction bar model generator

A fraction bar model is a rectangle divided into equal-width segments, with some segments shaded to show the numerator out of the total number of segments (the denominator). It is a common method in Singapore Math and most elementary curricula for showing fractions as measurable, equal parts.

Enter a numerator and denominator, then click Visualize. The tool draws a rectangle split into equal segments and shades the ones matching your numerator. If the fraction is improper, it adds additional whole rectangles below the first.

Bar models line fractions up on a shared straight edge, which makes it easier to compare two different fractions at a glance, especially with unlike denominators. Pie charts are better for the "parts of a round whole" intuition. This tool supports both plus a number line.

Yes. Enter your first fraction, then enter a second fraction in the comparison field. The tool draws both bars at the same width so you can see which fraction covers more of the bar, even when the denominators differ.
