Multiple Spinners
Multiple Spinner Builder – Interactive Probability Tool
The Multiple Spinner Builder lets students design, build, and test custom spinners right on the screen. Starting with a draggable template spinner, students can drop as many spinners as they need onto the workspace, each one fully interactive and easy to customize.
With a single click, teachers and students can choose the number of sections (2–10), edit spinner labels, drag spinners into position, and spin the arrow to generate outcomes. The Reset button clears the board instantly, while Random creates a fresh set of spinners for quick practice or exploration.
This hands-on digital manipulative helps students understand:
- How the number of sections affects probability
- Comparing likelihood across different spinners
- Independent events and repeated trials
- Designing fair vs. unfair spinners
- Probability experiments, predictions, and data collection
The clean layout, bold colors, and smooth drag-and-spin motion make it ideal for whole-class lessons, small-group instruction, or independent probability investigations. Perfect for grades 3–8 and aligned with probability standards across curricula.
Whether modeling chance experiments, comparing results, or building custom spinners for math games, this tool gives students a visual, intuitive way to explore probability.
