What fraction is shown?
How many parts are NOT shaded?
Shaded parts: 1 out of 4 = 1/4
Unshaded parts: 3 out of 4 = 3/4
Fraction: A number that shows part of a whole. It has a top number (numerator) and bottom number (denominator).
- Count how many parts are shaded (numerator)
- Count how many parts there are in total (denominator)
- Write as fraction: shaded/total
- Count unshaded parts separately if needed
The circle is divided into 4 equal parts
There is 1 part shaded
Shaded over total = 1/4
There are 3 parts not shaded
The fraction shown is 1/4. There are 3 parts NOT shaded.
• Numerator: Number of parts we have (shaded)
• Denominator: Total number of equal parts
• Equal parts: Essential for valid fractions
Are these fractions equal?
Which is bigger: 1/2 or 1/3?
Equivalent fractions: Different fractions that represent the same amount.
Both shapes show the same amount shaded, so 1/2 = 2/4
1/2 means 1 part out of 2 total, 1/3 means 1 part out of 3 total
When dividing the same whole into fewer parts (2 vs 3), each part is bigger, so 1/2 > 1/3
Yes, 1/2 and 2/4 are equal. 1/2 is bigger than 1/3.
• Equivalent fractions: Same amount, different numbers
• Comparison: Fewer total parts = bigger individual parts
• Same numerator: Smaller denominator = bigger fraction
What fraction is red?
What fraction is blue?
What fraction is red AND blue together?
Fraction addition: Adding parts of the same whole. When denominators are the same, add numerators.
1 part out of 4 total = 1/4 red
2 parts out of 4 total = 2/4 blue
1 part + 2 parts = 3 parts out of 4 total = 3/4
Red fraction: 1/4. Blue fraction: 2/4. Combined: 3/4.
• Addition: Add numerators when denominators are the same
• Same denominator: Parts are equal size
• Total: Sum of all parts cannot exceed whole
Definitions:
Fraction: A number that shows part of a whole. It has a top number (numerator) and bottom number (denominator).
Numerator: The top number showing how many parts we have.
Denominator: The bottom number showing how many equal parts there are in total.
Halves: When a shape is divided into 2 equal parts.
Thirds: When a shape is divided into 3 equal parts.
Quarters: When a shape is divided into 4 equal parts.
Equivalent fractions: Different fractions that show the same amount.
Core Rules:
1. All parts must be equal in size
2. Numerator = shaded parts
3. Denominator = total parts
4. Fraction = numerator/denominator
5. Shaded + unshaded = total parts
6. Same denominators allow addition of numerators
Step-by-Step Method:
Step 1: Count the total number of equal parts
Step 2: Count the number of shaded parts
Step 3: Write the fraction as shaded/total
Step 4: Simplify if possible (for older grades)
Step 5: Check your answer makes sense
Examples:
Simple: Circle cut in half = 1/2
Medium: Square with 2 of 4 parts shaded = 2/4
Advanced: Rectangle with 1 of 3 parts shaded = 1/3
Tips:
- Always count total parts first
- Make sure all parts are equal
- Draw lines to separate parts if needed
- Practice with real objects (pizza, cookies)
- Use different shapes to see the same fraction
Key Notes:
- The bigger the denominator, the smaller each part
- Same fraction can be shown in different shapes
- Equal parts are essential for fractions
- Equivalent fractions show same amount differently

What fraction is green?
What fraction is yellow?
What fraction is green OR yellow?
Mixed operations: Working with different parts of the same whole using addition.
2 parts out of 6 total = 2/6 green
1 part out of 6 total = 1/6 yellow
2 parts + 1 part = 3 parts out of 6 total = 3/6
3/6 = 1/2 (same amount, simpler fraction)
Green fraction: 2/6. Yellow fraction: 1/6. Combined: 3/6 or 1/2.
• Addition: Add numerators when denominators are the same
• Simplification: 3/6 = 1/2 (divide both by 3)
• Same whole: All parts come from same shape
Put them in order from smallest to largest.
Explain why 1/3 is bigger than 1/4 but smaller than 1/2.
Comparison: Determining which fraction represents a larger or smaller portion of the same whole.
1/4 = 1 part out of 4, 1/3 = 1 part out of 3. Since 3 < 4, 1/3 > 1/4
1/3 = 1 part out of 3, 1/2 = 1 part out of 2. Since 2 < 3, 1/2 > 1/3
1/4 < 1/3 < 1/2
1/3 is bigger than 1/4 because when dividing the same whole into fewer parts (3 vs 4), each part is larger. 1/3 is smaller than 1/2 because 2 parts are fewer than 3 parts, so each part is even larger.
Order: 1/4, 1/3, 1/2. 1/3 is bigger than 1/4 because 3 parts are fewer than 4 parts, making each part larger. 1/3 is smaller than 1/2 because 2 parts are fewer than 3 parts, making each part even larger.
• Same numerator: Smaller denominator = larger fraction
• Part size: Fewer total parts = larger individual parts
• Ordering: Compare using visual models or reasoning
