Understanding Decimals in Words

Learn to read and write decimal numbers using words!

What Are Decimal Words?

Decimals can be written as numbers (like 0.75) or in words (like "seventy-five hundredths").
When we write decimals in words, we say the whole number part first (if there is one), then "and", then the decimal part as if it were a fraction. The last word tells us the place value of the last digit.

How to Read Decimal Words

1️⃣ Find the "and" - it separates whole numbers from decimals

2️⃣ Read the decimal part like a fraction (tenths, hundredths, etc.)

3️⃣ Combine them to make the complete decimal number

Let's Practice Together!

Number Form:

A. 0.07

B. 2.3

C. 4.56

Parent Tips 🌟

  • Kitchen Math: When cooking, have your child read measurements like "one and a quarter cups" as "one and twenty-five hundredths" to connect words with decimals.
  • Money Talks: Use dollar amounts to practice - $3.45 is "three and forty-five hundredths dollars."
  • Decimal Scavenger Hunt: Look for decimals around the house (on rulers, measuring cups, etc.) and practice saying them in words.
