What Are Decimal Place Values?
Decimal numbers help us represent amounts less than one or between whole numbers.
Just like whole numbers have place values (ones, tens, hundreds), decimal numbers have place values too! After the decimal point, we have tenths, hundredths, thousandths, and more. Each place is 10 times smaller than the one before it.

How Decimal Places Work
1️⃣ The decimal point separates whole numbers from parts of numbers
2️⃣ The first digit after the decimal is tenths (1/10)
3️⃣ The second digit is hundredths (1/100)
4️⃣ The third digit is thousandths (1/1000)

Parent Tips 🌟
- Money makes sense: Use coins to teach decimals - dollars are ones, dimes are tenths, pennies are hundredths.
- Kitchen math: When baking, have your child measure ingredients like 0.75 cups of flour and identify each digit's place value.
- Place value hopscotch: Draw a place value chart on the ground and have your child hop to the correct place when you call out a digit.
