Free fraction games that make the whole and the parts visible.
Move fractions away from memorized rules and back into manipulable models: equal parts, fraction bars, number lines, equivalence, comparison, unlike denominators, decimals, and percents.

Model first
Fractions are not separate rules; they are different ways to represent the same whole.
Use these fun-math manipulatives before topic missions for projection, dragging, and parent explanations.
Fraction Partition Lab
Partition one whole into equal pieces, then change how many pieces are shaded. The bar makes numerator and denominator roles visible.
Equivalent Fraction Bars
Stacked bars all show the same proportional amount. Change the denominator and slide the numerator β green dots mark exact equivalents, pink bars show close-but-not-equal approximations.
Percent Grid Lab
Slide across a hundred-grid and watch percent, fraction, and decimal names stay connected.
Number Line Hopper
Hop along a number line and leave a visible trail. This standalone playground makes direction, distance, and operation signs visible.
Ratio Tape Diagram
Scale a tape diagram and watch both bars grow together. The bars compare by multiplication, not subtraction.
