Watch the bar fill as you type. Understand what percentages really mean — visually!
Percent means "out of 100." So 25% = 25/100 = 0.25. The grid above shows exactly how many squares out of 100 are shaded — making it easy to see what a percentage really is.
Use the buttons to switch between the three most common types: find what amount a percent equals, find what percent one number is of another, or find the original whole if you know a part and a percent.
This free interactive math tool helps students visualize and understand mathematical concepts. Instead of memorizing procedures, students can see how numbers work through visual models, manipulatives, and step-by-step animations. Research shows that visual learning in math leads to deeper conceptual understanding.
