1 whole unit can be split into 1,000 equal parts. Each part is one thousandth.

Or we can show the same thing this way:

One (1) whole unit	Split into ten equal parts (tenths)	Each tenth split into ten equal parts (hundredths)	Each hundredth split into ten equal parts	Each part is one thousandth

Numbers with place value
