Pick the shape that fits your lesson. This tool draws the same fraction as a pie chart, a bar model, or a number line, so you can switch between visual styles without retyping anything. Enter a fraction once, try each shape, and compare two fractions side by side to see which representation makes the concept click for your students.
Different students click with different shapes: some understand pie slices instantly, others need a bar to compare sizes, and others need a number line to see where a fraction sits between whole numbers. Reach for this tool when you want the flexibility to try more than one shape for the same fraction in a single lesson.
