What are Decimals?
Decimals represent parts of a whole number using a decimal point (.). The decimal point separates whole numbers from fractional parts.
Key Concepts:
Decimal Point (.) - The dot separating whole numbers from parts
Tenths Place - First position after the decimal (one part out of 10)
Hundredths Place - Second position after the decimal (one part out of 100)
Example: In the decimal 4.7, the number 4 represents whole units and 7 represents seven-tenths (0.7).
Solved Example: Understanding Decimals Visually
Problem: Represent 2.3 using a visual model and explain what it means.
Solution:
2.3 means "2 whole units and 3 tenths"
Visual: Two complete squares + three out of ten parts of another square shaded
Written form: 2 + 0.3 = 2.3
Read as: "Two point three"
Answer: 2.3 represents two complete wholes plus three-tenths of another whole.

Common Mistakes & Tips
Common Mistakes to Avoid:
Ignoring Place Value: Students often think 0.8 equals 8 because they focus only on the digit. Always emphasize that 0.8 means "eight-tenths," which is less than 1.
Comparing Without Alignment: When comparing 3.7 and 3.25, students may think 3.25 is larger because "25 is bigger than 7." Teach them to compare digit by digit from left to right.
Addition Alignment Errors: When adding 2.3 + 1.5, ensure decimal points are aligned vertically to avoid mistakes.
Zero Confusion: Students forget that 4.7 and 4.70 represent the same value. Trailing zeros after the decimal don't change the number.
Top 5 Pro-Tips:
Visualize with Grids: Use 10-square grids to represent tenths. Shading parts makes abstract decimals concrete and understandable.
Align Decimal Points: When adding or subtracting, always line up the decimal points vertically before calculating.
Compare Left to Right: To compare decimals, start from the leftmost digit and move right, just like whole numbers.
Use Money for Practice: Rupees and paise provide excellent real-world decimal practice (₹5.50 = 5 rupees and 50 paise).
Read Aloud Correctly: Practice saying "point" instead of "and" (read 6.4 as "six point four," not "six and four").
