Advanced Topics

Fractions: Parts of a Whole

Understanding Fractions

Fractions show parts of a whole, like slices of a pizza.

What is a Fraction?

A fraction has two numbers: the top number (numerator) tells how many parts you have, and the bottom number (denominator) tells how many parts make a whole.

Real-Life Fractions

When you cut a sandwich in half and eat one piece, you’ve eaten \( \frac{1}{2} \)! Fractions help with recipes, sharing, and measuring.

Comparing Fractions

The bigger the denominator, the smaller each piece. Practice comparing and recognizing common fractions like halves, thirds, and quarters.

Examples

  • 1/4 of a chocolate bar means 1 piece out of 4.

  • 3/8 of a pizza means 3 pieces out of 8.

In a Nutshell

Fractions help us talk about parts of things.
