Understanding Illustrated Decimals
Decimals help us represent numbers between whole numbers!
When we see illustrations of decimals, they often show parts of a whole. A grid of 100 squares can represent 1 whole, where each square is 0.01 (one hundredth). Similarly, a grid of 10 squares can represent 1 whole, where each square is 0.1 (one tenth).
How to Read Illustrated Decimals
1️⃣ Identify the whole - What does the complete illustration represent? (Usually 1.0)
2️⃣ Count the filled parts - How many squares or sections are colored in?
3️⃣ Determine the decimal - Divide the filled parts by the total parts to get your decimal number
Let's Practice with Examples!
Example 1: Tenths Grid
This grid represents 1 whole divided into 10 equal parts. What decimal is shown?
Shaded parts: 4/10
Example 2: Hundredths Grid
This grid represents 1 whole divided into 100 equal parts. What decimal is shown?
Shaded parts: 35/100
Parent Tips 🌟
- Use real-world objects - Help your child visualize decimals by using measuring cups, rulers, or money to show tenths and hundredths.
- Play decimal matching games - Create cards with decimal numbers and matching illustrations for a fun memory game.
- Connect to percentages - Show how decimals relate to percentages (0.25 = 25%) to help build multiple math connections.
