Fraction identification: Counting shaded parts over total equal parts
- Count the total number of equal parts
- Count the number of shaded parts
- Write the fraction as shaded/total
- Simplify if possible
The circle is divided into 4 equal parts
3 parts are shaded blue
Shaded parts over total parts = 3/4
3/4 cannot be simplified further
The fraction of the circle that is shaded is 3/4
• Equal parts: All parts must be the same size
• Numerator: Number of parts we have
• Denominator: Total number of equal parts
Fraction comparison: Determining which fraction represents a larger amount
We have 1/2 and 1/4
LCM of 2 and 4 is 4
1/2 = 2/4 (multiply both by 2)
2/4 > 1/4, so 1/2 > 1/4
1/2 is greater than 1/4 because 2/4 > 1/4
• Common denominator: Convert to same denominator for comparison
• Comparison: Compare numerators when denominators are equal
• Visual verification: 1/2 covers more area than 1/4
Remainder fraction: The fraction that remains after some parts are taken
Pizza is cut into 8 equal slices
5 slices are eaten
8 - 5 = 3 slices remain
Remaining slices over total slices = 3/8
3/8 of the pizza remains after eating 5 slices
• Subtraction: Remaining = Total - Eaten
• Fraction calculation: Remaining parts over total parts
• Equal parts: All slices must be the same size
Counting shaded parts over total parts
Using common denominators to compare
Applying fractions to daily situations
Finding what's left after parts are taken
Fraction: A number representing part of a whole
Equal parts: Parts that are the same size and shape
Numerator: Top number showing how many parts are taken
Denominator: Bottom number showing total equal parts
Remainder: What's left after some parts are used
Common denominator: Same bottom number allowing direct comparison
- Read carefully: Understand what the problem asks
- Identify parts: Count total and specific parts
- Write fraction: Shaded over total
- Compare if needed: Use common denominators
- Simplify: Reduce to lowest terms
- Verify: Check if answer makes sense
Equivalent fractions: Different fractions that represent the same amount
Circle divided into 2 parts, 1 shaded = 1/2
Circle divided into 4 parts, 2 shaded = 2/4
Both circles have the same amount shaded
1/2 = (1×2)/(2×2) = 2/4
1/2 and 2/4 are equivalent because they represent the same amount
• Equivalence: Same amount, different divisions
• Visual comparison: Shaded areas are equal
• Mathematical verification: Multiply numerator and denominator by same number
Multi-step fraction problem: Finding remainder after multiple actions
Cookie is divided into 6 equal parts
2 parts eaten + 1 part given away = 3 parts taken
6 - 3 = 3 parts remain
Remaining parts over total parts = 3/6
3/6 = 1/2 (divide both by 3)
3/6 (or 1/2) of the cookie remains after eating 2 parts and giving 1 part away
• Multi-step calculation: Add all parts taken first
• Subtraction: Remaining = Total - Taken
• Simplification: 3/6 reduces to 1/2
Fraction practice problems: Exercises designed to reinforce fraction concepts through repeated application

• Denominator is the total number of equal parts
• Compare fractions using common denominators
• Simplify fractions when possible
Identifying fractions from visual models
- Circle with 2 of 4 parts shaded
- Rectangle with 3 of 6 parts shaded
- Square with 1 of 4 parts shaded
Comparing fractions
- Which is larger: 1/3 or 1/4?
- Which is larger: 2/5 or 3/5?
- Which is larger: 1/2 or 2/4?
Real-life applications
