Unit 7, Lesson 3
Ordering Rational Numbers
Accelerated 6
Preparation
Lesson Narrative
In this lesson, students practice ordering rational numbers and using precise language to describe the relationships between numbers plotted on a number line (MP6).
Students begin by using the symbol <, >, or = to compare pairs of numbers. Next, they work with a partner to put sets of cards in order from least to greatest. The cards include both positive and negative rational numbers. Students then compare the locations of points on a horizontal number line using phrases, such as “greater than,” “less than,” “opposite,” and “negative.”
- Compare rational numbers without a context, and express (orally and in writing) the comparisons using the phrases “greater than,” “less than,” and “opposite.”
- Comprehend that all negative numbers are less than all positive numbers.
- Order rational numbers from least to greatest, and explain (orally and through other representations) the reasoning.
Let’s order rational numbers.
Required Preparation
Copy each set of cards on a different color of paper so they can easily be sorted for the next class.
