Place Value Tool

Summary

The Place Value Tool breaks any number — whole or decimal — into its individual digits and labels each one with its correct place name. Students can see at a glance that the "3" in 4,321 sits in the hundreds place, or that the "7" in 0.07 is in the hundredths place. The expanded form is shown alongside, reinforcing how place values combine to make the full number.

How it works

1. Type any number (whole or decimal) into the input field.
2. The tool parses each digit and maps it to its place name — ones, tens, hundreds, thousands, and so on.
3. Decimal digits are labeled tenths, hundredths, thousandths, and beyond.
4. Each digit appears in a color-coded card showing its place name and its value contribution.
5. The expanded form of the number is displayed below the chart.

Use cases

• Verify digit positions when reading large numbers aloud.
• Classroom demonstrations on a projector or smartboard.
• Self-study for students preparing for standardized math tests.
• Quickly produce expanded-form notation for homework problems.
