Pie Chart

Pie Chart Builder is an intuitive drag-and-drop tool that lets students construct custom pie charts and explore fractions, data displays, and percentages in a hands-on way. Students drag colored circles onto the large pie to build categories, and the chart updates instantly—no calculations required.

How It Works

1. Drag colored circles onto the pie to create wedges.
2. Click the text under each circle (labeled “Add label”) to rename categories.
3. A live legend on the right shows each category’s label along with counts and percentages.
4. Click the title above the chart (labeled “Add title”) to give your chart a custom name.
5. Press Reset to clear the chart and start over with new data.

This drag-and-drop manipulative makes abstract ideas concrete, gives teachers flexibility to model many different data sets, and helps students see math come alive through color, shape, and interaction.
