Fraction Exploration

Number Line Fraction Visualization
The number line below divides 0 to 1 into fractions defined by the sliders to the left. Try to predict equivalent fractions for different denominators, then verify visually.
Bar Visualization of Fractions.
The applet below provides side by side comparisons of two fractions defined by the sliders. Set up a fraction on the left and try to determine all equivalent fractions. Verify your answers visually using the right.
