Understanding Decimal Numbers
Decimals help us represent numbers that aren't whole!
Just like fractions, decimals show parts of a whole number. We use a decimal point to separate the whole number from its parts. The first digit after the decimal point represents tenths, the next represents hundredths, and so on.
How to Read Illustrated Decimals
1️⃣ Look at the whole grid - it represents 1 whole
2️⃣ Count the shaded parts - each small square is 0.01 (1 hundredth)
3️⃣ Combine whole and parts - add them together for your decimal
Practice Examples
Example 1: How much is shaded?
Example 2: Create 0.75 by clicking squares!
Current value: 0.00
Parent Tips 🌟
- Use real-world examples: Show decimals with money (dollars and cents) or measurements (like 1.5 liters of juice) to make them more concrete.
- Play decimal games: Create a "decimal war" card game where you compare decimal numbers, or use a ruler to measure objects to the nearest tenth/hundredth.
- Connect to fractions: Help your child see that 0.5 is the same as ½ and 0.25 equals ¼ to build connections between different number forms.
