Thousandths are very small numbers. During the next lesson, you'll apply your understanding of decimals and decimal place value to comparing decimals to the thousandths.

### Questions to Discuss

- Ask your child to write the following numbers in decimal form as you read them aloud:

Four hundred sixty-nine thousandths (0.469)

One and eighty-seven hundredths (1.87) - Now, ask her to write each of the numbers in expanded notation using fractions.

(4 × 1/10) + (6 × 1/100) + (9 × 1/1,000)

(1 × 1) + (8 × 1/10) + (7 × 1/100)
