🔢 Model Decimals and Fractions

📖 What the Section Is About

In this lesson, students use models such as grids, number lines, and base-ten blocks to show the relationship between decimals and fractions. These visual tools help learners understand that decimals and fractions can represent the same value. Modeling also makes it easier to compare and convert between the two forms.

🎯 Learning Objectives

✅ Represent fractions using decimal grids and number lines
✅ Model decimals as parts of a whole
✅ Show how a fraction and a decimal can be equivalent
✅ Compare decimals and fractions using visual models
✅ Build confidence in switching between fractions and decimals

🧪 Examples

  • A 10-square grid shaded 4 parts = ⁴/₁₀ = 0.4

  • A 100-square grid shaded 25 parts = ²⁵/₁₀₀ = 0.25

  • On a number line, halfway between 0 and 1 = ⁵/₁₀ = 0.5

📘 Key Vocabulary and Definitions

  • Model: A picture or object that represents a math idea

  • Grid: A set of squares used to show parts of a whole

  • Number Line: A straight line showing numbers in order

  • Equivalent: Different forms (fraction or decimal) showing the same value
