Enter any ratio and see it as bars, dots and a pie. Scale it up, find equivalent ratios, explore part-to-whole!
A ratio compares two quantities. The ratio 2:3 means for every 2 of one thing, there are 3 of another — like 2 blue tiles for every 3 red tiles. Ratios can be scaled up or down while keeping the same relationship.
Part-to-part (2:3) compares two parts to each other. Part-to-whole compares one part to the total (2:5 or 3:5). Both ways of thinking are useful in different situations.
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.
All math tools on SmartOnlineGames are aligned with Common Core State Standards for Mathematics and are designed for students in grades K through 8. They are completely free, require no login or account creation, and work on any device including tablets, Chromebooks, and interactive whiteboards.
Interact with the visual tool above to explore the concept. Try different inputs and observe how the output changes. Teachers can use this tool for whole-class demonstrations or independent practice. Parents can use it for homework help or math enrichment at home.
