📊 Results
Design your spinner, spin it, and watch real results build up. Compare what actually happens vs what the math says should happen!
Theoretical probability is what the math predicts — with 4 equal sections, each should come up 25% of the time. Experimental probability is what actually happened in your spins. The more you spin, the closer they get — this is called the Law of Large Numbers!
The bar chart shows how many times each color was landed on. The table shows the experimental % vs the theoretical %. Try spinning 100 times and see how close they get!
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.
