Place Value Chart
Type any number and see it split into place value columns from billions to thousandths, with the digit and its value in each, plus the expanded form. Blank charts print too.
| Millions 106 | Hundred thousands 105 | Ten thousands 104 | Thousands 103 | Hundreds 102 | Tens 101 | Ones 10 | Tenths 0.1 | Hundredths 0.01 |
|---|---|---|---|---|---|---|---|---|
| 4 | 5 | 6 | 2 | 3 | 1 | 8 | 7 | 5 |
| 4000000 | 500000 | 60000 | 2000 | 300 | 10 | 8 | 0.7 | 0.05 |
The top row is the place, the middle row is the digit sitting there, and the bottom row is what that digit is actually worth. Add the bottom row together and you get your number back.
What a place value chart shows
A digit on its own tells you almost nothing. The 5 in 500 and the 5 in 0.05 are the same symbol doing two completely different jobs, and the only thing separating them is where they sit. A place value chart makes that position visible by giving every column a name and a size. Read left to right and each column is worth ten times less than the one before it, all the way past the decimal point without interruption.
Place and value are not the same thing
This is the distinction that trips people up. The place is the name of the column, such as hundreds or tenths. The value is what the digit is worth once it sits there. In 4,562,318 the digit 5 has a place of hundred thousands and a value of 500,000. Writing every digit as its value and adding them up gives you the expanded form, which is the clearest way to see why a number means what it means.
What happens after the decimal point
Nothing special, which is the point. The pattern of dividing by ten simply keeps going: ones, then tenths, then hundredths, then thousandths. There is no "oneths" column, because the ones column already sits immediately to the left of the point and the decimal point itself is not a place, only a marker showing where the whole numbers stop. That is also why 0.5 and 0.50 are equal: adding a zero on the far right adds a column worth nothing.
Worth knowing
- Every column is worth ten of the column to its right. That single rule generates the entire chart in both directions.
- Zeros are not filler. The 0 in 502 is what keeps the 5 in the hundreds column instead of the tens.
- Print the blank chart and write a number in by hand. Placing the digits yourself is what makes the idea stick.
- Reading the expanded form out loud is the fastest way to hear whether a number has been misread.
- Nothing you type is stored. The chart is built on our server and discarded immediately.
