# Lesson 11

Large Numbers on a Number Line

### Lesson Purpose

The purpose of this lesson is for students to use place value understanding to locate large numbers on a number line and describe number relationships in which one multi-digit number is ten times as much as another.

### Lesson Narrative

In this lesson, students both estimate and precisely locate numbers through the hundred-thousands place on a number line. This lesson is designed to deepen students’ understanding of the relative position of multi-digit numbers to multiples of 100, 1,000, 10,000, and 100,000. They learn that when numbers are related by ten times as much, they are located in a position on a number line with the same relationship to surrounding benchmark numbers. Students will use the number line in the next section to round large numbers.
