Understanding Decimal Numbers
Decimals help us show numbers that are less than 1!
Just like fractions, decimals represent parts of a whole. We use a decimal point to separate whole numbers from parts of numbers. The first digit after the decimal point shows tenths, and the second digit shows hundredths.
How to Read Illustrated Decimals
1️⃣ Look at how many full squares are colored (whole number part)
2️⃣ Count how many parts of the next square are colored (tenths)
3️⃣ For more precision, count tiny squares (hundredths)
Interactive Examples
Example 1: Tenths
What decimal does this picture show?
The answer is 3.6!
We have 3 full squares and 6 tenths of another square colored.
Example 2: Hundredths
What decimal does this picture show? (Each small square is 0.01)
The answer is 2.73!
We have 2 full squares, 7 tenths (the big colored part), and 3 extra hundredths (the small colored part).
Parent Tips 🌟
- Use real-world examples: Show decimals when measuring ingredients (0.5 cups of flour) or money ($3.25) to make it practical.
- Create decimal art: Have your child color grid paper to represent different decimal numbers.
- Play decimal games: Use dice to create decimal numbers and have your child draw what they look like.
