Pie Chart Maker

A Pie Chart Maker for Teachers

A chart tool for the classroom has to clear a low bar that most tools miss: no accounts, no installs, no ads mid-lesson, and fast enough to use live on the projector while thirty students watch. This one clears it. Open the page, type data, the chart appears.

That makes it useful in two directions. As a teaching aid, you can build a chart with the class, tally survey answers on the board, type them in, and watch fractions turn into slices. As a prep tool, you can chart grade distributions, reading levels, or attendance patterns for your own records and parent nights.

Charts print cleanly, and the print-friendly palette keeps slices distinguishable on the staff room's black and white printer.

When to use it

  • Live demos of fractions, percentages, and angles
  • Class survey results, from favorite books to lunch choices
  • Grade distribution summaries for your records or parent evenings
  • Printable worksheet charts for reading exercises

Tips for a better chart

  • Build charts live with student data. Engagement doubles when the chart is about them.
  • Ask prediction questions before revealing labels: which slice is biggest? By how much?
  • Use the share URL to send the exact chart to students, so they can modify it as an exercise.
  • For worksheets, hide labels and have students calculate percentages from the raw values themselves.

Frequently asked questions

Do students need accounts to use it?

No. There is nothing to sign up for, which also means no student data or emails are collected. It works on school Chromebooks and tablets straight from the browser.

Can I share a chart with my class?

Yes. Every chart has a share URL that encodes the whole chart in the link. Post it in Google Classroom and every student opens the same chart, ready to explore or edit.

How can I use it to teach fractions?

Enter simple data like 1, 1, and 2. Ask what fraction each slice is, then reveal the percentage labels. The link between 1/4, 25 percent, and a 90 degree slice becomes visible instead of abstract.

Will charts print clearly in black and white?

Choose the print-friendly palette. Its colors are picked to stay distinguishable in grayscale, so photocopies keep working.
