Learning Scenario: Pizza Sharing Party

The Challenge:

You have a pizza cut into 8 equal slices. If you eat 3 slices, what fraction of the pizza did you eat? What fraction is left?

Pizza Sharing Challenge

Fraction Solution:

Total slices: 8 (the whole)
Slices eaten: 3 (the part)
Fraction eaten: 3/8 (three-eighths)
Fraction left: 5/8 (five-eighths)

Fraction Basics Guide: Parts and Whole

Fraction Notation:

Numerator (top number)

How many parts you have

Denominator (bottom number)

How many equal parts the whole is divided into

Fraction bar (line)

Separates numerator and denominator

Example: 3/8

3 is the numerator

You have 3 slices

8 is the denominator

The pizza is cut into 8 equal slices

Read as "three-eighths"

3 out of 8 equal parts

Visual Fraction Models

Common Visual Models:

Pizza slices

Easy to understand and visualize

Fraction circles

Circular models divided into parts

Fraction bars

Rectangular models for comparison

Number lines

Show fractions as points on a line

Pizza Examples:

1/2: Half of a pizza (4 out of 8 slices)

1/4: Quarter of a pizza (2 out of 8 slices)

3/8: Three-eighths of a pizza (3 out of 8 slices)

5/8: Five-eighths of a pizza (5 out of 8 slices)

Practice Examples

Pizza Sharing Problems:

8 slices, eat 3: 3/8 eaten, 5/8 left

6 slices, eat 2: 2/6 eaten, 4/6 left

4 slices, eat 1: 1/4 eaten, 3/4 left

12 slices, eat 5: 5/12 eaten, 7/12 left

Reading Fractions:

1/2: one-half

1/3: one-third

2/4: two-fourths

3/8: three-eighths
