Unit 4, Lesson 11
Large Numbers on a Number Line
Grade 4
Preparation
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 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.

Teacher Reflection Questions
Reflect on times you observed students listening to one another’s ideas today in class. What norms would help each student better attend to their classmates’ ideas in future lessons?
