Fraction Fundamentals

45 min Grade 4 Interactive Math Lab

Learning Objectives

  • Understand fractions as parts of a whole
  • Compare fractions with different denominators
  • Add and subtract fractions

Key Concepts

Numerator

The top number - how many parts we have

Denominator

The bottom number - total equal parts

Equivalent Fractions

Different fractions that represent the same value

Theory

A fraction represents part of a whole. The denominator tells us how many equal parts, and the numerator tells us how many of those parts we have. **Visual Representation:** - ½ means 1 out of 2 equal parts - ¾ means 3 out of 4 equal parts **Finding Equivalent Fractions:** Multiply or divide both numerator and denominator by the same number: ½ = 2/4 = 3/6 = 4/8 (all equal!)

Examples

Are ²⁄₄ and ½ equivalent?

Solution: Yes! 2÷2=1 and 4÷2=2, so ²⁄₄ = ½
