Fractions: Parts of a Whole
Year 7 Mathematics Understanding Fractions and Their Parts
What is a Fraction?
A fraction represents a part of a whole It shows how many equal parts we're talking about Fractions are everywhere in daily life Examples: sharing pizza, measuring ingredients, time on a clock
Parts of a Fraction
{"left":"Numerator: The top number - tells us how many parts we have\nDenominator: The bottom number - tells us how many equal parts make up the whole","right":"Example: In 3/4, the 3 is the numerator and 4 is the denominator\nThe line between them means 'divided by'"}
Hands-On Fraction Building
Use fraction circles or bars to create fractions Build 1/2, 1/3, 2/5 with your manipulatives Draw what you create on paper Label the numerator and denominator

Fractions on a Number Line
Fractions live between whole numbers 0 is where we start, 1 is one whole 1/2 is exactly halfway between 0 and 1 Smaller denominators mean bigger pieces
Quick Check: Can You Identify These Fractions?
Look at the visual representations What fraction does each shape show? Remember: count the shaded parts (numerator) and total parts (denominator) Raise your hand when you know the answer!
What We've Learned Today
Fractions represent parts of a whole Numerator = parts we have, Denominator = total equal parts We can show fractions with pictures, manipulatives, and number lines Some different fractions represent the same amount (equivalent fractions) Homework: Find a real-life fraction example to share next lesson!
