Lesson Overview
Identifying, Ordering, and Comparing Rational Numbers
A rational number is any number that can be written as a fraction where the denominator is not zero. This includes fractions, decimals, mixed numbers, and whole numbers. The lesson introduces this definition and shows how to place rational numbers on a number line and compare them using <, >, and =.
The six-page lesson walks through rational number identification and ordering strategies. Students complete 20 practice problems and check their work using the answer key on page 6.
How to Use This Lesson
1. Introduce rational numbers and their definition (pages 1–2). Show that fractions, decimals, and whole numbers are all rational.
2. Practice ordering and comparing rational numbers together (pages 3–4). Use the number line and common denominators as comparison tools.
3. Assign the 20 practice problems (page 5) independently. Review answers using the key on page 6.
