Thousandths are three places after the point.

The word and marks the point.

Two and twenty-five thousandths is 2.025.

Read it: Read a decimal by its places

4.372 is 4 ones, 3 tenths, 7 hundredths and 2 thousandths. Each digit is worth its count of the place it stands under.

  1. Read the place names across the top of the chart.
  2. Say each digit with its place: 7 hundredths is 0.07.
  3. The point sits between the ones and the tenths, and thousandths are the third place after it.

Each place is a tenth of the place to its left, so ten thousandths make one hundredth.

4.372 is 4 + 0.3 + 0.07 + 0.002: one part for each digit.

In words it is four and three hundred seventy-two thousandths, and the word "and" marks the point.

A digit's worth is its count of the place it stands in.

Writing four and twenty-five thousandths as 4.25, which is twenty-five hundredths.

Thousandths take three places after the point, so twenty-five thousandths is 0.025, and the number is 4.025.

Write eight and sixteen thousandths as a decimal. — 8.016. Thousandths take three places after the point, so it is 8.016: 16 is written 016.

Grade 5 · Reading decimals using place value

Each digit lives in a place. To the left of the dot is ones; to the right we have tenths, hundredths, and thousandths.

Start with the whole number part. The three is in the ones place, so we say 'three'.

The decimal point is read as the word 'and'. It's the only time we say 'and' when reading numbers.

Now look at the digits after the dot: four, eight, two.

We read all three digits together as one whole number — four hundred eighty-two.

The last digit, the two, sits in the thousandths place — so we name the whole group 'thousandths'.

Put it together: four hundred eighty-two thousandths.

All together now: three and four hundred eighty-two thousandths.

That's how we read a decimal to the thousandths! Whole part, 'and', then the decimal digits with their place name.
