➗ Decompose Fractions into Unit Fractions Using Models
📖 What the Section Is About
In this unit, students learn how to break down fractions into smaller unit fractions. A unit fraction has a numerator of ¹ and shows one part of the whole. By using models, students see how larger fractions can be represented as a sum of unit fractions.
🎯 Learning Objectives
✅ Understand the meaning of a unit fraction (¹/ₙ).
✅ Break down fractions like ³/₄ into unit fractions.
✅ Use visual models to show decomposition.
✅ Write fractions as sums of unit fractions in different ways.
✅ Build a strong foundation for fraction addition.
🧪 Examples
-
³/₄ = ¹/₄ + ¹/₄ + ¹/₄
-
⁵/₆ = ¹/₆ + ¹/₆ + ¹/₆ + ¹/₆ + ¹/₆
-
⁴/₈ = ¹/₈ + ¹/₈ + ¹/₈ + ¹/₈
